The role of allergic and nonallergic rhinitis on success of type 1 cartilage tympanoplasty / El papel de la rinitis alérgica y no alérgica en el éxito de la timpanoplastia de cartílago tipo 1

Objective: To investigate the role of allergic rhinitis (AR) and non-allergic rhinitis (NAR) on success of type 1 cartilage tympanoplasty. Methods: This prospective study was conducted on 60 patients who had type 1 cartilage tympanoplasty. The patients were divided into three groups as no-rhinitis (n = 28), NAR (n = 18) and AR (n = 14) groups, based on their symptoms, skin prick tests and/or serum specific IgE levels. AR and NAR groups were treated for their rhinitis symptoms both pre- and postoperatively. The patients were followed up for a minimum of 6 months and compared for graft success rates and audiological outcomes. Results: Three study groups were similar for age, gender distributions and preoperative air-bone gaps (p = 0.780, p = 0.167 and p = 0.676, respectively). Postoperative graft perforation rate was 0% in no-rhinitis and AR groups while it was 16.7% in NAR group, with a significant difference among three groups (p = 0.034). The comparison of three study groups for change in the postoperative air bone gaps in comparison with preoperative air bone gaps did not yield any statistically significant result (p = 0.729). Conclusion: Although AR does not result in failure of type 1 cartilage tympanoplasty in patients treated for rhinitis compared to the control group, NAR does. Pre- and postoperative treatment of patients for rhinitis and employment of cartilage graft may be the key factors for success of surgery in patients with AR. Further studies with a larger sample size are needed.(AU)

Objetivo: Investigar el papel de la rinitis alérgica (AR) y la rinitis no alérgica (NAR) en el éxito de la timpanoplastia de cartílago tipo 1. Métodos: Este estudio prospectivo se realizó en 60 pacientes con timpanoplastia de cartílago tipo 1. Los pacientes se dividieron en tres grupos como libres de rinitis (n = 28), NAR (n = 18) y AR (n = 14) según sus síntomas, pruebas cutáneas y/o niveles de IgE específica en suero. Los grupos AR y NAR fueron tratados antes y después de la operación por síntomas de rinitis. Los pacientes fueron seguidos durante al menos 6 meses y se compararon las tasas de éxito del injerto y los resultados audiológicos. Resultados: Los tres grupos de estudio fueron similares en cuanto a la edad, la distribución por sexos y el espacio entre el aire y el hueso preoperatorio (p = 0,780, p = 0,167 y p = 0,676, respectivamente). Mientras que la tasa de perforación del injerto postoperatorio fue del 0 % en el grupo sin rinitis y AR, fue del 16,7 % en el grupo NAR, y hubo una diferencia significativa entre los tres grupos (p = 0,034). La comparación de los tres grupos de estudio con los espacios óseos aéreos preoperatorios para el cambio en los espacios óseos aéreos posoperatorios no arrojó un resultado estadísticamente significativo (p = 0,729). Conclusión: Aunque AR no falla en la timpanoplastia de cartílago tipo 1 en pacientes tratados por rinitis en comparación con el grupo control, NAR sí lo hace. El tratamiento pre y postoperatorio de pacientes con rinitis y el uso de injertos de cartílago pueden ser factores clave para el éxito de la cirugía en pacientes con RA. Se necesitan más estudios con tamaños de muestra más grandes.(AU)

The novel retro-conchal approach for middle ear surgeries: Our experience in 196 patients / El nuevo abordaje retro-conchal para cirugías del oído medio: nuestra experiencia en 196 pacientes

Background This study aimed to describe a new proposed retro-conchal approach for middle ear surgery and to evaluate its advantages and postoperative impact. Methodology A retrospective case-series study was held at a tertiary university hospital from March 2008 to April 2022. We included 196 adult patients who were candidates for middle ear surgery because of chronic otitis media. The retro-conchal approach entailed a skin incision on the medial conchal surface 1 cm anterior to the auricular sulcus. It allowed the harvesting of the required size of conchal cartilage and temporalis fascia through the same incision with access into the middle ear and complete exposure to the mastoid process. In addition, we evaluated the use of this approach in tympanoplasty, including cholesteatoma surgeries with at least one-year postoperative follow-up. Result The long-term follow-up (22.9 ± 6.37 months) revealed that most operated cases (89%) did not develop postoperative sequelae related to this approach. On the other hand, 22 patients (11%) developed adverse outcomes, with a statistically significant difference regarding adverse outcomes as the P-value <0.001. Conclusion According to our experience with a relatively large number of patients, the retro-conchal technique was practical for various middle ear surgeries. It allowed optimal access to different middle ear areas and obtaining large-sized conchal cartilage and temporalis fascia (if needed) through the same incision without needing extra surgical steps. In addition, it was a safe maneuver without significant adverse outcomes in the long-term follow-up. (AU)

Antecedentes Este estudio tuvo como objetivo describir una nueva propuesta de abordaje retroconchal para la cirugía del oído medio y evaluar sus ventajas e impacto postoperatorio. Metodología Se realizó un estudio retrospectivo de serie de casos en un hospital universitario de tercer nivel desde marzo de 2008 hasta abril de 2022. Se incluyeron 196 pacientes adultos candidatos a cirugía de oído medio por otitis media crónica. El abordaje retroconchal implicó una incisión cutánea en la superficie medial de la concha 1 cm anterior al surco auricular. Permitió la recolección del tamaño requerido de cartílago de la concha y fascia temporal a través de la misma incisión con acceso al oído medio y exposición completa al proceso mastoideo. Evaluamos el uso de este abordaje en la timpanoplastia, incluidas las cirugías de colesteatoma con un seguimiento postoperatorio de al menos un año. Resultado El seguimiento a largo plazo (22,9 ± 6,37 meses) reveló que la mayoría de los casos operados (89%) no desarrollaron secuelas postoperatorias relacionadas con este abordaje. Por otro lado, 22 pacientes (11%) desarrollaron secuelas menores, con diferencia estadísticamente significativa en cuanto a la ocurrencia de secuelas como el valor P < 0,001. Conclusión De acuerdo con nuestra experiencia con un número relativamente grande de pacientes, la técnica retroconchal fue práctica para varias cirugías del oído medio. Permitió un acceso óptimo a diferentes áreas del oído medio y obtener cartílago de la concha y fascia temporal (si es necesario) de gran tamaño a través de la misma incisión sin necesidad de pasos quirúrgicos adicionales. Fue una maniobra segura y sin complicaciones significativas en el seguimiento a largo plazo. (AU)

Estudio retrospectivo de 544 timpanoplastias con cartílago y pericondrio: resultados anatómicos y funcionales / A retrospective study of 544 tympanoplasty with cartilage and perichondrium: anatomical and functional results

Introducción: el cierre de las perforaciones timpánicas se realiza con diferentes materiales, entre ellos el cartílago y el pericondrio. En este estudio se compararon los resultados anatómicos y funcionales obtenidos con ambos materiales, y se evaluaron posibles factores asociados con los buenos resultados. Material y métodos: estudio retrospectivo en pacientes intervenidos de timpanoplastia sin mastoidectomía entre el 1 de enero de 2001 y el 31 de diciembre de 2018. Resultados: se incluyeron 544 timpanoplastias. En la mayoría se utilizó cartílago (78,5 %) y en el resto pericondrio. El cartílago se utilizó con mayor frecuencia en los menores de 18 años (p=0,001), perforaciones totales y subtotales (p=0,000) y timpanoplastias secundarias y terciarias (p=0,008). No hubo diferencias en el tiempo de seguimiento (15,68 ± 22,18 meses frente al 12,86 ± 14,9 meses, p=0,169). La tasa de éxito anatómico fue mayor en el grupo de cartílago, sin diferencias en los resultados auditivos (82 % con cartílago y 78,3 % con pericondrio). El éxito anatómico se relacionó con la técnica utilizada para la reconstrucción con cartílago, mientras que los resultados auditivos se asociaron significativamente con el estado de la mucosa del oído medio y la cadena de huesecillos en el momento de la cirugía y el éxito anatómico posquirúrgico. Conclusiones: con el cartílago se consiguieron mejores resultados anatómicos que con el pericondrio, sin diferencias a nivel funcional. Sin embargo, los resultados funcionales empeoraron si había patología a nivel del oído medio y en ausencia de restauración anatómica.

Introduction: Different materials are used to close tympanic perforations. This stu-dy aimed to compare anatomical results obtained with cartilage and perichondrium and evaluate factors associated with successful results. Material and method: Re-trospective study of patients who underwent tympanoplasty without mastoidectomy between January 1, 2001, and December 31, 2018. Demographic data, ear pathology, surgical intervention, and anatomical and functional results were collected. Results:544 tympanoplasty were included. Cartilage was the most used (78.5%). Cartilage was used more frequently in children under 18 years (p = 0.001), to reconstruct total and subtotal perforations (p = 0.000) and in secondary and tertiary tympanoplasty (p = 0.008). Follow-up time did not differ between the two groups (15.68 ± 22.18 months vs. 12.86 ± 14.9 months, p = 0.169). The anatomical success rate was higher in the cartilage group, with no significant differences in hearing outcomes (82% with cartilage and 78.3% with perichondrium). Anatomical success was related to the technique used for cartilage reconstruction (monoblock or palisade). Hearing re-sults were significantly associated with the state of middle ear mucosa at the time of surgery, the state and mobility of the ossicle chain, and post-surgical anatomical suc-cess. Conclusions: Cartilage achieved better anatomical results than perichondrium. Both materials were comparable on a functional level. However, the functional re-sults worsen if there is pathology of the middle ear (mucosa or chain of ossicles) and anatomical restoration is not achieved.

Mastoid obliteration and canal wall reconstruction with posterior auricular artery (PAA) fascia-periosteum flap

Objective: Unstable cavities are defined as cavities with cerumen accumulation that need frequent cavity cleaning in the out-patient clinic, cavities that are intolerant to water due to risk of infection or that are subject to frequent infection and otorrhoea. The objective of this study is to address the problem of troublesome mastoid cavities, with the performance of secondary mastoid obliteration and canal wall reconstruction, using a novel posterior auricular artery (PAA) fascia-periosteum flap.Materials and methodsA prospective study was designed, only secondary obliterations were included. Unstable mastoid cavities were defined as Merchant grade 2 or 3 and were included for surgery.ResultsAt 12 months of follow up, a complete external auditory canal (EAC) and a self-cleaning ear were achieved in all 23 patients. Completely dry ears were achieved in 21 patients (91.3%). An air-bone gap improvement of 5dB was achieved.ConclusionMastoid obliteration and EAC reconstruction are effective procedures to treat troublesome post canal wall down mastoid cavities. They improve quality of life and enable patients to overcome ear discharge. A standard EAC size enables the utilization of conventional hearing aids, it also reduces the need for constant mastoid cleaning and decreases healthcare expenses. The PAA flap seems to be an effective procedure to achieve all these features, as it is used to obliterate the mastoid and becomes a structural component of the neo-EAC. (AU)

Objetivo: Las cavidades inestables se definen como cavidades que presentan acumulación de cerumen que requieren limpieza en la consulta de manera frecuente, son cavidades intolerantes al agua por su elevado riesgo de infección o tienen frecuentes infecciones y otorrea. El objetivo de este estudio es abordar el problema de las cavidades mastoideas problemáticas con una obliteración mastoidea secundaria y reconstrucción del conducto auditivo externo (CAE) usando un colgajo fascio-perióstico de la arteria auricular posterior.Materiales y métodosSe diseñó y realizó un estudio prospectivo, solo se incluyeron obliteraciones secundarias. Las mastoides inestables fueron definidas según la clasificación de Merchant como grado 2 o 3 y fueron incluidas para la cirugía.ResultadosA los 12 meses de seguimiento, se consiguió un CAE completo y autolimpiable en los 23 pacientes. Se lograron oídos completamente secos en 21 casos (91,3%). Se obtuvo una mejoría media en la brecha aire-hueso de 5dB.ConclusiónLa obliteración mastoidea y la reconstrucción del CAE son procedimientos eficaces para tratar mastoides problemáticas posmastoidectomías abiertas. Mejoran la calidad de vida de los pacientes y son efectivas para solventar la otorrea recurrente. La obtención de un CAE de tamaño estándar es importante para permitir que el paciente pueda utilizar una audioprótesis estándar, además de reducir la necesidad de limpieza de la cavidad de manera constante y la dependencia del paciente a los controles en la consulta, disminuyendo así el gasto en sanidad. El colgajo de arteria auricular posterior parece ser una herramienta útil para lograr todas estas características, y también es usado para obliterar las mastoides y se convierte en un componente estructural del neo-CAE.

Titanium prostheses versus stapes columella type 3 tympanoplasty: a comparative prospective study / Timpanoplastia tipo III com próteses de titânio versus columela do estribo: um estudo prospectivo comparativo

Abstract Introduction: Tympanoplasty is a surgical procedure designed to reconstruct the mechanisms of sound transmission in the middle ear. Objective: Analyze, from an audiological point of view, patients with chronic otitis media undergoing type 3 tympanoplasty major columella with total ossicular replacement titanium prosthesis or with cartilage graft stapes columella. Methods: This is a prospective analytical study, carried out at the otorhinolaryngology outpatient clinic in a tertiary care hospital, through the evaluation of 26 patients with chronic otitis media who underwent tympanoplasty using different materials for auditory rehabilitation such as titanium prostheses or cartilage autografts. Results: There was no statistically significant association between the group factors (cartilage or titanium reconstruction) and preoperative variables. There was no statistically significant association between the postoperative characteristics of the patients and the type of reconstruction. Neither subjective improvement (hearing improvement) nor residual perforation were associated with a type of material. The via factor was the only one that showed a statistically significant difference once air-conduction pathway improved more than bone-conduction pathway, decreasing the air-bone gap. Conclusion: There was no statistical difference between the two groups in relation to the audiometric improvement. There was hearing improvement in both groups. More studies must be done with a longer follow-up to better evaluate the outcome.

Resumo Introdução: A timpanoplastia é um procedimento cirúrgico que visa reconstruir os mecanismos de transmissão do som na orelha média. Objetivo: Analisar, do ponto de vista audiológico, pacientes com otite média crônica submetidos à timpanoplastia tipo 3 com columela maior, com prótese de reconstituição ossicular total de titânio, ou com columela de estribo com enxerto de cartilagem. Métodos: Estudo prospectivo analítico, feito no ambulatório de otorrinolaringologia de um hospital terciário, por meio da avaliação de 26 pacientes com otite média crônica submetidos à timpanoplastia com diferentes materiais para reabilitação auditiva, como próteses de titânio ou autoenxertos de cartilagem. Resultados: Não houve associação estatisticamente significante entre os fatores de grupo (reconstrução com cartilagem ou titânio) e variáveis pré-operatórias. Não houve associação estatisticamente significante entre as características pós-operatórias dos pacientes e o tipo de reconstrução; nem melhoria subjetiva (melhoria auditiva) ou perfuração residual foram associadas a um tipo de material. O fator via foi o único que demonstrou diferença estatisticamente significante, uma vez que a condução por via aérea apresentou maior melhoria do que a condução por via óssea, reduziu o gap aéreo-ósseo. Conclusão: Não houve diferença estatística entre os dois grupos em relação à melhoria audiométrica. Houve melhoria auditiva em ambos os grupos. Mais estudos com seguimento mais longo devem ser feitos para uma melhor avaliação da evolução.

El 68,8% de participantes con RE, presentaron tensor fold (TF) completo. Se observó una relación significativa entre TF completo e IT bloqueado con RE (p=0,026 y 0,003 respectivamente). Conclusiones: Los hallazgos más frecuentes fueron el TF completo e IT bloqueado, estos tuvieron asociación significativa con la presencia de RE en pacientes con OMC no colesteatomatosa.

Objective: To describe the endoscopic findings of the ventilation pathways found during type I tympanoplasty in patients with non-cholesteatomatous COM (chronic otitis media). Materials and methods : Cross-sectional descriptive study, we evaluated 32 patients with non-cholesteatomatous COM with and without epitympanic retraction (ER) (Grade I-III, according to Mirko Tos classification), with a history of type I tympanoplasty (June, 2018 - January, 2020) in the otorhinolaryngology service of the Arzobispo Loayza National Hospital. Patients with previous middle ear surgeries, with cholesteatomatous COM, with ER grade IV and surgical acts not digitally stored were excluded. Results: 71.8% of patients presented ER (Grade I 3.0%, grade II 30.0% and grade III 56.5%), all presented blocked tympanic isthmus (TI). 68.8% of participants with ER presented complete tensor fold (TF). A significant relationship was observed between complete TF and blocked IT with ER (p=0.026 and 0.003, respectively). Conclusions: The most frequent findings were complete TF and blocked IT, these had a significant association with the presence of ER in patients with non-cholesteatomatous COM.

Use of nasal mucosa graft in tympanoplasty / Uso do enxerto de mucosa nasal na timpanoplastia

Abstract Introduction Tympanoplasty techniques with different types of graft have been used to close tympanic perforations since the 19th century. Tragal cartilage and temporalis fascia are the most frequently used types of graft. They lead to similar functional and morphological results in most cases. Although little published evidence is present, nasal mucosa has also been shown to be a good alternative graft. Objective Surgical and audiological outcomes at the six-month follow-up in type I tympanoplasty using nasal mucosa and temporalis fascia grafts were analyzed. Methods A total of 40 candidates for type I tympanoplasty were randomly selected and divided into the nasal mucosa and temporalis fascia graft groups with 20 in each group. The assessed parameters included surgical success; the rate of complete closure of tympanic perforation and hearing results; the difference between post- and pre-operative mean quadritonal airway-bone gap, six months after surgery. Results Complete closure of the tympanic perforation was achieved in 17 of 20 patients in both groups. The mean quadritonal airway-bone gap closures were11.9 and 11.1 dB for the nasal mucosa and temporalis fascia groups, respectively. There was no statistically significant difference between the groups. Conclusion The nasal mucosa graft can be considered similar to the temporal fascia when considering the surgical success rate of graft acceptance and ultimate audiological gain.

Resumo Introdução Técnicas de timpanoplastia com diferentes tipos de enxerto têm sido usadas para fechar perfurações timpânicas desde o século XIX. A cartilagem tragal e a fáscia temporal são os tipos de enxerto mais usados, com resultados funcionais e morfológicos semelhantes na maioria dos casos. Embora ainda com poucas evidências publicadas, a mucosa nasal tem se mostrado uma boa opção de enxerto. Objetivo Comparar os resultados cirúrgicos e audiológicos da timpanoplastia tipo I com enxerto de mucosa nasal e de fáscia temporal em seis meses de seguimento. Método Foram selecionados aleatoriamente 40 pacientes candidatos a timpanoplastia tipo I divididos nos grupos enxerto de mucosa nasal e de fáscia temporal com 20 em cada grupo. Os parâmetros avaliados incluíram sucesso cirúrgico, ou seja, a taxa de fechamento completo da perfuração timpânica, e resultados audiológicos; diferença entre o gap quadritonal médio do gap aéreo-ósseo pré e pós-operatório após seis meses da cirurgia. Resultados O fechamento completo da perfuração timpânica foi alcançado em 17 de 20 pacientes no grupo mucosa nasal, como também no grupo fáscia temporal. O ganho quadritonal médio do gap aéreo-ósseo foi de 11,9 dB no grupo mucosa nasal e 11,1 dB no grupo fáscia temporal, respectivamente. Não houve diferença estatisticamente significante entre os grupos. Conclusão O enxerto de mucosa nasal pode ser considerado semelhante ao da fáscia temporal quando se considera o sucesso cirúrgico de pega do enxerto e o ganho audiológico.

Colesteatoma: influencia de la técnica quirúrgica y el estadio EAONO/JOS en los resultados audiológicos / Cholesteatoma: Influence of surgical technique and EAONO/JOS stage on audiological results

Antecedentes y objetivo: El tratamiento del colesteatoma es quirúrgico en la mayoría de los casos. Cuando está indicado, es preferible optar por una técnica quirúrgica reconstructiva con el doble propósito de eliminar la enfermedad y preservar o mejorar la audición del paciente. En 2017 se publicó una nueva clasificación del colesteatoma por parte de la European Academy of Otology and Neuro-Otology/Japanese Otological Society (EAONO/JOS). El objetivo de este estudio es determinar la influencia que tanto la técnica quirúrgica empleada como la clasificación de la enfermedad tienen en los resultados auditivos de los pacientes. Materiales y métodos: Se realiza un estudio retrospectivo que incluye pacientes intervenidos de colesteatoma mediante una técnica reconstructiva entre 2012 y 2017. A partir de la tomografía computarizada (TC) prequirúrgica de cada paciente se estadifica la enfermedad según la clasificación de la EAONO/JOS. Los datos audiológicos obtenidos mediante audiometría tonal liminar (ATL) pre y postoperatoria son analizados en función de la técnica quirúrgica empleada y según el estadio de la enfermedad. Resultados: Se incluyen 143 pacientes con umbrales auditivos sin diferencias significativas antes de la cirugía. Al año de la intervención, el umbral medio auditivo (pure tone average [PTA]) aéreo y el umbral diferencial auditivo (UDA) medio mejoran significativamente (p=0,01 y p=0,001) en toda la muestra. Los pacientes intervenidos con técnica cerrada en dos tiempos presentan mejores resultados en el PTA aéreo postoperatorio y UDA medio posquirúrgico que los operados mediante técnica abierta (p=0,007 y p=0,014). El PTA aéreo postoperatorio y el UDA medio postoperatorio mejoran en los pacientes intervenidos con técnica cerrada en dos tiempos quirúrgicos (p=0,001 y p=0,013), en comparación con la audición previa que presentaban. El UDA medio postoperatorio también mejora significativamente en los pacientes operados mediante técnica abierta (p=0,008). Conclusiones: Todas las técnicas quirúrgicas reconstructivas producen una mejora significativa de la audición al año de la intervención. En nuestro estudio esta mejora es significativamente superior con una timpanoplastia con mastoidectomía cerrada en dos tiempos quirúrgicos.(AU)

Introduction and objective: The treatment of cholesteatoma is surgical in most cases. When it is indicated, it is preferable to choose a reconstructive surgical technique with the dual purpose of eradicating the disease and preserving or improving the patient's hearing. In 2017, the European Academy of Otology and Neuro-Otology/Japanese Otological Society (EAONO/JOS) published a new cholesteatoma classification. The aims of this study are to determine the influence of the surgical technique use and this classification on patient's hearing outcomes. Methods: A retrospective study that include patients who underwent reconstructive surgery of cholesteatoma between 2012 and 2017 is carried out. Based on pre-surgical computed tomography (CT) images, disease is staged according to the EAONO/JOS classification. Hearing outcomes obtained by pre and postoperative pure tone audiometry are analysed according to the surgical technique used and according to the stage of the disease. Results: 143 patients with no statistically significant differences in hearing thresholds before surgery are included. One year after surgery, all the patients’ airbone pure tone average (PTA) and mean differential auditory threshold have improved significantly (P = .01 and P = .001). Those patients who undergo tympanoplasty with two-stage canal wall up mastoidectomy presente better postsurgical air PTA and postsurgical mean differential auditory threshold outcomes (P=.007 and P=.014) than those patients who underwent tympanoplasty with canal wall down mastoidectomy. Moreover, the patients who underwent tympanoplasty with two-stage canal wall up mastoidectomy had improved airbone PTA and mean differential auditory threshold one year after the surgery with statistical significance (P=.001 and P=.013). The mean differential auditory threshold is also better (P=.008) in the patients who undergo tympanoplasty with canal wall down mastoidectomy one year after the procedure. Conclusions: Reconstructive surgical techniques improve hearing one year after surgery. In our study, this improvement is significantly greater with tympanoplasty with two-stage canal wall up mastoidectomy.(AU)

Pediatric tympanoplasty: A paradigm shift?

Introduction and objectives: Pediatric tympanoplasty is still a matter of controversy. Many factors have been associated with the surgical outcome of tympanoplasty in children, including age, size and location of the perforation, surgical technique and Eustachian tube dysfunction. The optimal approach and timing of this surgery remains controversial.This study aims to evaluate the outcomes of pediatric tympanoplasty and analyze factors that may influence the success of this surgery.Materials and methodsA retrospective review was conducted which included children from 5 to 15 years old that underwent tympanoplasty with or without ossiculoplasty for chronic tympanic perforation in a tertiary care university hospital over a 6-year period. Patients were divided in two age groups (5 to ≤10 years old and >10 to 15 years old). Children with cholesteatoma or that underwent simultaneous mastoidectomy were excluded.Results83 cases were included. Average age was 10.7±2.1 years and mean follow-up time was 9 months. Of the cases, 21.7% were revision surgeries. Successful closure of the tympanic membrane perforation was achieved in 76.9% of primary surgeries and 55.6% of revision surgeries. Most of the patients improved their conductive hearing-deficit. No statistical difference in graft failure was noted regarding age, presence of craniofacial dysmorphism and surgical approach. The use of simple graft (temporal muscle fascia or tragus perichondrium) was significantly superior in primary surgery (p<0.05). We also found a significant difference between the location of the perforation and revision surgery, with anterior perforations showing a higher risk (p<0.05).ConclusionsPediatric tympanoplasty is effective in repairing chronic tympanic perforations. In our study, accepted predictors of surgical outcome such as age and surgical approach were not associated with graft failure. (AU)

Introducción y objetivos: La timpanoplastia pediátrica continúa siendo una cuestión controvertida. Se han asociado muchos factores al resultado quirúrgico de la timpanoplastia en niños, incluyendo la edad, el tamaño y la localización de la perforación, la técnica quirúrgica y la disfunción de la trompa de Eustaquio. El enfoque óptimo y la elección del momento de esta cirugía continúan siendo controvertidos. El objetivo de este estudio es evaluar los resultados de la timpanoplastia pediátrica y analizar los factores que pueden influir en el éxito de esta cirugía.Materiales y métodosSe realizó una revisión retrospectiva, que incluyó a niños de 5 a 15 años de edad sometidos a timpanoplastia con o sin osiculoplastia para perforación timpánica crónica en un hospital universitario terciario a lo largo de un periodo de 6 años. Se dividió a los pacientes en 2 grupos de edad (de 5 a ≤10 años, y >10 a 15 años). Se excluyó a los niños con colesteatoma o a los que se sometió simultáneamente a mastoidectomía.ResultadosSe incluyeron 83 casos. La edad media fue de 10,7±2,1 años, y el tiempo medio de seguimiento fue de 9 meses. El 21,7% de los casos fueron cirugías de revisión. El cierre exitoso de la perforación de la membrana timpánica se logró en el 76,9% de las cirugías primarias, y el 55,6% de las cirugías de revisión. La mayoría de los pacientes mejoró su pérdida auditiva conductiva. No se apreció diferencia estadística en cuanto a fracaso del injerto en términos de edad, presencia de dismorfismo craneofacial y abordaje quirúrgico. El uso de injerto simple (fascia de músculo temporal o pericondrio tragal) fue significativamente superior en la cirugía primaria (p<0,05). Encontramos también una diferencia significativa entre la localización de la perforación y la cirugía de revisión, presentando las perforaciones anteriores un riesgo más alto (p<0,05).(AU)

Endoscopic tympanoplasty with inlay cartilage graft in an university hospital / Timpanoplastia endoscópica com enxerto de cartilagem inlay em hospital universitário

Abstract Introduction Tympanoplasty is the surgical procedure aimed at the reconstruction of the tympanic membrane and restoration of the sound conducting mechanism. It can be performed with several types of access and grafts and is considered successful when it achieves complete closure of the tympanic perforation and sound conduction improvement. Objective To describe the prevalence of successful closure of tympanic perforations and auditory results of endoscopic tympanoplasty with an inlay tragus cartilage graft. Methods Retrospective study developed at a tertiary referral hospital. Patients with central tympanic perforations and intact ossicular chains operated with endoscopic tympanoplasty with inlay tragus cartilage graft were included. The neo-tympanum integrity index was evaluated, and the preoperative and postoperative auditory parameters were compared using the paired Student's t-test. Results We identified 83 endoscopic tympanoplasties with inlay cartilage, of which 63 (76 %) had an intact neo-tympanum and 20 (24 %) had residual perforations. The preoperative air-bone gap was, on average, 18 ± 8.9 dBHL, and the postoperative 11 ± 10 dBHL (p = 0.0005), showing reduction in 71 % and complete recovery in 27 %. The mean preoperative speech recognition threshold was 35 ± 13.5 and the postoperative SRT was 27 ± 14.4 (p = 0.0002). The preoperative tritonal mean was 34 ± 14.3 and the postoperative was 24 ± 15 (p = 0.0002). Conclusion In this series, endoscopic tympanoplasties with inlay tragus cartilage graft showed a 76 % prevalence of complete closure of the tympanic perforation, with significant improvement in the auditory parameters.

O SRT pré-operatório médio foi 35 ± 13,5 e o pós-operatório 27 ± 14,4 (p = 0,0002). A média tritonal pré-operatória foi 34 ± 14,3 e a pós-operatória 24 ± 15 (p = 0,0002). Conclusão Nesta casuística, as timpanoplastias endoscópicas com cartilagem de tragus inlay apresentaram fechamento completo da perfuração timpânica em 76% dos casos, com melhoria significativa dos parâmetros auditivos.

Type I Tympanoplasty: surgical success and prognostic factors

Objectives: To evaluate success rate of type I tympanoplasty in adults and to investigate the importance of selected prognostic factors on graft uptake.Material and methodsRetrospective medical chart review of 155 patients who underwent Type I Tympanoplasty, in our department, from January 2013 to December 2017. Graft uptake rate was evaluated and the effects of prognostic factors on surgical outcome such as sex, smoking and otological surgery history, status of the contralateral ear, size and location of the perforation, middle ear mucosa status, surgical approach and graft material. Preoperative and postoperative audiometric data were collected, and the functional success was determined.ResultsThe overall surgical anatomical success rate was 75%. Analysis of the selected variables, identified as independent prognostic factors of anatomical unsuccess (95% CI): smoking (OR=3.29, p<.01), middle ear tympanosclerosis (OR=2.96; p=.04). Perforations above 50% of the tympanic membrane area had a borderline effect on graft uptake (p=.05). There was a significative improvement in the average air conduction thresholds of 7.44dB and an ABG closure rate at 10dB and 20dB was achieved in 47% and 84.5%, respectively. Patients who received temporalis fascia graft had similar hearing gain compared to patients who underwent cartilage tympanoplasty (7.7 vs. 7.3dB, p=.79).ConclusionType I tympanoplasty is an effective and safe procedure with a high anatomical success rate in the treatment of mucosal COM. Poorer outcomes were found in patients with smoking habits, in those with tympanosclerosis of middle ear mucosa and in larger perforations. These prognostic factors should be considered in surgical planning and patients should be advised to quit smoking. Tympanoplasty with cartilage graft had a hearing outcome comparable to temporalis fascia graft and should be considered in high-risk patients. (AU)

Objetivos: Evaluar la tasa de éxito de la timpanoplastia tipo I en adultos e investigar la importancia de los factores pronósticos seleccionados en la absorción del injerto.Material y métodosRevisión retrospectiva de los registros médicos, de 155 pacientes que se sometieron a timpanoplastia tipo I en nuestro departamento, desde enero de 2013 hasta diciembre de 2017. Se evaluó la tasa de absorción del injerto y los efectos de los factores pronósticos en el resultado quirúrgico, como el sexo, el tabaquismo y la cirugía otológica. antecedentes, estado del oído contralateral, tamaño y ubicación de la perforación, estado de la mucosa del oído medio, abordaje quirúrgico y material de injerto. Se recogieron datos audiométricos preoperatorios y postoperatorios y se determinó el éxito funcional.ResultadosLa tasa general de éxito anatómico quirúrgico fue del 75%. Análisis de las variables seleccionadas, identificadas como factores pronósticos independientes de fracaso anatómico (IC 95%): tabaquismo (OR = 3,29, p < 0,01), timpanosclerosis del oído medio (OR = 2,96; p = 0,04). Las perforaciones por encima del 50% del área de la membrana timpánica tuvieron un efecto límite en la absorción del injerto (p = 0,05). Hubo una mejora significativa en los umbrales promedio de conducción de aire de 7,44 dB y se logró una tasa de cierre ABG con 10 dB y 20 dB en 47% y 84,5%, respectivamente. Los pacientes que recibieron injerto de fascia temporal tuvieron una ganancia auditiva similar en comparación con los pacientes que se sometieron a timpanoplastia de cartílago (7,7 frente a 7,3 dB, p = 0,79).ConclusiónLa timpanoplastia tipo I es un procedimiento efectivo y seguro con una alta tasa de éxito anatómico en el tratamiento de la otitis media crónica. Se encontraron resultados más pobres en pacientes con hábito de fumar, en aquellos con timpanosclerosis en la mucosa del oído medio y en perforaciones más grandes. (AU)

Resultados As taxas de sucesso entre os grupos de estudo e controle em relação à "pega" do enxerto foram de 97% e 93%, respectivamente. Não foi observada diferença significante entre os grupos em relação aos valores médios dos tons puros, melhoria do gap ou redução do aéreo-ósseo para menos de 20 dB no pós-operatório. No entanto, melhores resultados foram observados no grupo de estudo. Conclusão A técnica de enxerto em ilha associada e paliçada preservado em pericôndrio é um métodofácil, com altas taxas de sucesso tanto do enxerto quanto dos resultados auditivos.

Comparação da abordagem endoscópica transcanal e microscópica na timpanoplastia tipo 1

Resumo Introdução: A timpanoplastia endoscópica é uma cirurgia minimamente invasiva que pode ser feita através de uma abordagem exclusivamente transcanal. O uso de endoscópios em procedimentos otológicos tem aumentado no mundo todo. A abordagem endoscópica facilita a timpanoplastia transcanal mesmo em pacientes com canal auditivo externo estreito e com uma protrusão da parede anterior. Objetivos: O presente estudo teve como objetivo comparar os resultados cirúrgicos e audiológicos das abordagens endoscópica transcanal e microscópica convencional na timpanoplastia tipo 1. Método: As taxas de sucesso do enxerto, os resultados auditivos, as complicações e a duração da cirurgia em pacientes submetidos a timpanoplastia endoscópica e microscópica entre outubro de 2015 e abril de 2018 foram analisados retrospectivamente. Resultados: As taxas de sucesso do enxerto foram de 94,8% e 92,9% para o grupo endoscópico e microscópico, respectivamente (p > 0,05). Os valores de gap aéreo-ósseo no pós-operatório melhoraram significantemente em ambos os grupos (p < 0,001). A duração média da cirurgia foi significantemente menor no grupo endoscópico (média de 34,9 minutos) em relação ao grupo microscópico (média de 52,7 minutos) (p < 0,05). O tempo médio de internação foi de 5,2 horas (variação de 3-6 horas) no grupo operado por endoscopia e de 26,1 horas (variação de 18-36 horas) no operado por microscopia (p < 0,05). Conclusão: A timpanoplastia transcanal via endoscópica é uma opção razoável à timpanoplastia microscópica convencional no tratamento da otite média crônica, com taxas de sucesso de enxertos e resultados auditivos comparáveis à microscópica.

Comparison of temporal muscle fascia and tragal cartilage perichondrium in endoscopic type 1 tympanoplasty with limited elevation of tympanomeatal flap / Comparação entre fáscia do músculo temporal e pericôndrio de cartilagem tragal na timpanoplastia endoscópica tipo 1 com descolamento limitado do retalho timpanomeatal

Abstract Introduction Elevation of tympanomeatal flap is one of the basic steps of tympanoplasty. A satisfactory level of anatomic and functional success can be achieved by using different grafts with limited tympanomeatal flap elevation. Objectives We aimed to compare the anatomic and functional success of tragal cartilage perichondrium and temporal muscle fascia in cases of endoscopic type 1 tympanoplasty performed with limited tympanomeatal flap elevation. Methods In total, 81 cases (33 females, 48 males, mean age 22.1<±<10.1 years, interval 18-49 years) which underwent transcanal endoscopic type 1 tympanoplasty with limited elevation of tympanomeatal flap were included the present study. All cases were divided into two groups as tragal cartilage perichondrium (group A) and temporal muscle fascia (group B). The comparison of the groups were made considering the pre- and postoperative air-bone gap and the tympanic membrane status. Results There was no statistically significant difference between Group A and Group B in preoperative and in postoperative air-bone gap values (p<=<0.608 and 0.529, respectively). In Group A and B, postoperative air-bone gap values demonstrated significant decrease compared to the preoperative values (p<=<0.0001). Group A and group B did not demonstrate significant differences between postoperative improvements of air-bone gap values (p<=<0.687). Graft retention success was 92.6% in group A while it was 90.0% in group B. There was no statistically significant difference between the groups in terms of graft retention success (p<=<0.166). Conclusion In accordance with the results of this study, we believe that both tragal cartilage perichondrium and temporal muscle fascia, and also in limited tympanomeatal flap elevation in endoscopic tympanoplasty are all eligible for result in safe and successful surgery.

Resumo Introdução O descolamento do retalho timpanomeatal é uma das etapas básicas da timpanoplastia. Um nível satisfatório de sucesso na restauração anatômica e funcional pode ser alcançado com o uso de diferentes enxertos e descolamento limitado do retalho timpanomeatal. Objetivos Comparar os resultados anatômicos e funcionais entre o uso de pericôndrio de cartilagem tragal e de fáscia do músculo temporal em timpanoplastias endoscópicas tipo 1 feitas com descolamento limitado do retalho timpanomeatal. Método Foram incluídos no estudo 81 pacientes (33 mulheres, 48 homens, média de 22,1 ± 10,1 anos, variação de 18-49 anos), submetidos a timpanoplastia endoscópica transcanal tipo 1 com descolamento limitado do retalho timpanomeatal. Todos os casos foram divididos em dois grupos: pericôndrio da cartilagem tragal (grupo A) e fáscia do músculo temporal (grupo B). Na comparação dos grupos consideraram-se o gap aéreo-ósseo, pré e pós-operatório, e a condição da membrana timpânica. Resultados Não houve diferença estatisticamente significante entre os grupos A e B no pré e pós-operatório (p = 0,608 e 0,529, respectivamente). Nos grupos A e B, os valores do gap aéreo-ósseo no pós-operatório demonstraram redução significante em relação aos valores pré-operatórios (p = 0,0001). Os grupos A e B não demonstraram diferenças significantes entre as medidas pré e pós-operatórias dos valores dos gaps (p = 0,687). O sucesso da retenção do enxerto foi de 92,6% no grupo A, enquanto no grupo B foi de 90,0%, não ocorreu diferença estatisticamente significante entre os grupos (p = 0,166). Conclusão De acordo com os resultados deste estudo, acreditamos que tanto o pericôndrio da cartilagem tragal como a fáscia do músculo temporal, usados com descolamento limitado do retalho timpanomeatal na timpanoplastia endoscópica, são elegíveis para uma cirurgia segura e bem-sucedida.

Endoscopic cartilage tympanoplasty: full thickness and partial thickness tragal graft / Timpanoplastia endoscópica com enxerto de cartilagem tragal de espessura parcial ou total

Abstract Introduction: Cartilage is the grafting material of choice for certain disorders of the middle ear. The indications for its routine use remain controversial due to the possible detrimental effect on post-operative hearing. Objective: The present study was carried out to report a personal experience with "tragal cartilage shield" tympanoplasty to compare the results, in terms of graft uptake and hearing improvement, of endoscopic cartilage shield technique using either partial thickness or full thickness tragal cartilage for type 1 tympanoplasty and to highlight the tips for single-handed endoscopic ear surgery. Methods: Fifty patients with safe chronic suppurative otitis media, assisted at out-patient department from February 2014 to September 2015 were selected. They were randomly allocated into two groups, 25 patients were included in group A where a full thickness tragal cartilage was used and 25 patients included in group B where a partial thickness tragal cartilage was used. Audiometry was performed 2 months after the surgery in all cases and the patients were followed for one year. Results: Out of the total of 50 patients 39 (78%) had a successful graft take up, amongst these 22 belonged to group A and 17 belonged to the group B. The hearing improvement was similar in both groups. Conclusion: This study reveals that endoscopic tragal cartilage shield tympanoplasty is a reliable technique; with a high degree of graft take and good hearing results, irrespective of the thickness. Furthermore, the tragal cartilage is easily accessible, adaptable, resistant to resorption and single-handed endoscopic ear surgery is minimally invasive, sutureless and provides a panoramic view of the middle ear.

Resumo Introdução: A cartilagem é o material de enxerto de escolha no tratamento cirúrgico de certas condições clínicas da orelha média. Devido ao possível efeito prejudicial na audição pós-operatória, as indicações para seu uso rotineiro ainda são controversas. Objetivo: Relatar a experiência dos autores com a timpanoplastia tipo 1 endoscópica usando cartilagem tragal e comparar os resultados entre a cartilagem tragal com espessura parcial e espessura total, em termos de integração do enxerto e melhoria da audição. O estudo também buscou apresentar sugestões para cirurgia endoscópica de orelha média com uma única mão (single-handed endoscopic ear surgery). Método: Foram selecionados 50 pacientes com otite média crônica supurativa, atendidos neste ambulatório entre fevereiro de 2014 e setembro de 2015, alocados aleatoriamente em dois grupos: 25 pacientes foram incluídos no grupo A, no qual uma cartilagem tragal de espessura total foi usada e outros 25 pacientes foram incluídos no grupo B, no qual foi usada uma cartilagem tragal de espessura parcial. Em todos os casos, uma audiometria foi feita dois meses após a cirurgia; os pacientes foram acompanhados por um ano. Resultados: Dos 50 pacientes, o enxerto foi bem-sucedido em 39 (78%), entre os quais 22 pertenciam ao grupo A e 17 pertenciam ao grupo B. A melhoria da audição em ambos os grupos foi muito semelhante. Conclusão: O estudo indicou que a timpanoplastia endoscópica com cartilagem tragal é uma técnica confiável, com alto grau de integração do enxerto e bons resultados de audição, independentemente da espessura usada. Além disso, a cartilagem tragal é facilmente acessível, adaptável e resistente à reabsorção; a cirurgia endoscópica é minimamente invasiva, sem sutura e proporciona uma visão panorâmica da orelha média.

Results of endoscopic transcanal tympanoplasty performed by a young surgeon in a secondary hospital / Resultados da timpanoplastia transcanal endoscópica realizada por um jovem cirurgião em um hospital secundário

Abstract Introduction: Tympanoplasty is performed to close the tympanic membrane perforation and recover the hearing level of patients with non-suppurative chronic otitis media. Endoscopic tympanoplasty has recently been increasingly preferred by ear nose and throat surgeons to treat tympanic membrane perforations. Objective: The aim of this study is to discuss the outcomes of patients undergoing endoscopic tympanoplasty performed by a young surgeon in a secondary hospital in the context of the literature. Methods: Fifty patients undergoing endoscopic Type 1 tympanoplasty between February 1, 2017 and February 1, 2018, were included. The patients' age, gender, perforation side and size, preoperative and postoperative pure tone audiometry, graft failure, postoperative pain and complication status were evaluated. Results: The graft success rate was 94% at 6 months postoperatively. Audiometry thresholds were obtained at frequencies of 0.5, 1, 2 and 4 kHz. Preoperative pure tone audiometric thresholds were 41.6, 36.3, 34.1, and 39.1 dB, and postoperative, 6 months after surgery, 19.5, 17.8, 17.5, and 20.8 dB. Pure tone audiometry air-bone gaps at the same frequencies changed from 30.5, 24.6, 22.2, and 28.6 dB preoperatively, to 11.0, 9.3, 8.6, and 13.9 dB 6 month after the surgery. There was a statistically significant improvement between the preoperative and postoperative pure tone audiometry, and air bone gaps at all measured frequencies (p < 0.05). Conclusion: Endoscopic transcanal cartilage tympanoplasty has become more commonly performed by otolaryngologists due to the shortening of operation and hospitalization times as well as similar audiological results to those obtained with microscopic tympanoplasty. The surgical and audiological results of a young ear nose throat specialist can reach a similar level of success to those of experienced surgeons, due to a fast learning curve.

Resumo Introdução: A timpanoplastia é realizada para fechar a perfuração da membrana timpânica e restaurar a audição de pacientes com otite média crônica não-supurativa. Recentemente, a timpanoplastia endoscópica tem se tornado a técnica preferida por cirurgiões otorrinolaringologistas, com indicação crescente em casos de perfurações timpânicas. Objetivo: O objetivo deste estudo é discutir os resultados em pacientes submetidos a timpanoplastia endoscópica realizada por um jovem cirurgião em um hospital secundário, no contexto da literatura. Método: Cinquenta pacientes submetidos a timpanoplastia endoscópica Tipo 1 entre 1° de fevereiro de 2017 e 1° de fevereiro de 2018 foram incluídos. A idade dos pacientes, sexo, lado e tamanho da perfuração, limiares da audiometria tonal pré-operatória e pós-operatória, falha do enxerto, dor pós-operatória e ocorrência de complicações foram avaliados. Resultados: A taxa de sucesso do enxerto foi de 94% aos 6 meses de pós-operatório. Nas frequências de 0,5, 1, 2 e 4 kHz, a audiometria tonal pré-operatória mostrava limiares de 41,6; 36,3; 34,1 e 39,1 dB e a pós-operatória após 6 meses, revelou limiares de 19,5; 17,8; 17,5 e 20,8 dB. Nas mesmas frequências, os gaps aéreo-ósseos pré-operatório na audiometria tonal eram de 30,5; 24,6; 22,2 e 28,6 dB e com 6 meses de pós-operatório, de 11,0; 9,3; 8,6 e 13,9 dB. Houve melhora estatisticamente significante entre os limiares da audiometria tonal pré- e pós-operatória em todas as frequências (p < 0,05). Houve diferença estatisticamente significante entre os gaps aéreo-ósseo pré- e pós-operatório, ocorrendo diminuição dos mesmos em todas as frequências (p < 0,05). Conclusão: A timpanoplastia endoscópica com cartilagem por via transcanal tem sido mais comumente realizada pelo otorrinolaringologista devido ao menor tempo de cirurgia e hospitalização e resultados audiológicos semelhantes aos com o uso de microscópico. Os resultados cirúrgicos e audiológicos de um jovem especialista em otorrinolaringologia podem atingir um nível semelhante ao de cirurgiões experientes, com uma rápida curva de aprendizado.

Resultados quirúrgicos de la timpanoplastia tipo I durante los años 2014 al 2019, en el Hospital Universitario Clínica San Rafael de Bogotá / Surgical results of type I tympanoplasty during 2014 to 2019, at Hospital Universitario Clínica San Rafael, Bogotá

Introducción: Las perforaciones timpánicas son una patología otológica frecuente tanto en población adulta como pediátrica. El daño hacia la membrana timpánica puede ser ocasionada por diversos factores como explosiones, traumas penetrantes, barotraumas e infecciones. Los síntomas más comunes incluyen el tinnitus, plenitud aural e hipoacusia. En los casos en los que es necesario realizar un tratamiento quirúrgico se opta por las timpanoplastias. El objetivo de este estudio es determinar la efectividad del cierre anatómico a través de esta técnica. Adicionalmente, identificar las comorbilidades asociadas, las causas por la que se decide realizar el procedimiento quirúrgico y las características sociodemográficas de la población intervenida. Objetivo general: Determinar la frecuencia de las reperforaciones timpánicas postoperatorias a los tres y seis meses, que fueron sometidos a timpanoplastia tipo I en el Hospital Universitario Clínica San Rafael de Bogotá, Colombia., durante los años 2014 al 2019. Materiales y métodos: estudio de tipo retrospectivo, descriptivo y de corte transversal, donde se incluyeron pacientes adultos y pediátricos del servicio de otorrinolaringología del Hospital Universitario Clínica San Rafael de Bogotá, Colombia, con antecedente de perforaciones timpánicas durante los años 2014 al 2019 y que fueron intervenidos con timpanoplastia tipo I. Se evaluaron resultados postquirúrgicos, principalmente las perforaciones posteriores a la cirugía con técnica medial "over-under" utilizando injerto de cartílago de concha y fascia temporal. Resultados: Se intervinieron 47 pacientes. 62% fueron de sexo femenino y 38% de sexo masculino. Se evidenció reperforación posoperatoria en 8.5% del total de la muestra. Ninguno antes de tres meses, 1 paciente entre 3 y 6 meses y 3 pacientes después de 6 meses posoperatorios. La causa más frecuente de la timpanoplastia tipo I fue la infecciosa, (66%). La comorbilidad asociada más frecuentemente a las perforaciones fue la otitis media crónica (OMC), en el 51%. Las audiometrías mostraron una mejoría del 17% y del 20% entre el PTA preoperatorio y posoperatorio, en el oído derecho y en el oído izquierdo, respectivamente. Conclusiones: La timpanoplastia tipo I con técnica over under se considera exitosa para el cierre anatómico de las perforaciones timpánicas, evaluado a los tres y seis meses posoperatorios, con porcentajes que se igualan a los reportados en estudios similares en la literatura. Los resultados audiométricos no mostraron una mejoría estadísticamente significativa en ambos oídos por lo cual se deben continuar realizando estudios para evaluar otros factores asociados a las perforaciones como otitis media crónica y colesteatoma, entre otros.

Introduction Tympanic perforations are a frequent otological pathology in both adult and pediatric populations. Damage to the tympanic membrane can be caused by various factors such as explosions, penetrating trauma, barotraumas, and infections. The most common symptoms include tinnitus, aural fullness, and hearing loss. In cases where surgical treatment is necessary, tympanoplasties are chosen. The objective of this study is to determine the effectiveness of anatomical closure through this technique. Additionally, to identify the associated comorbidities, the causes for which the surgical procedure was decided to be performed, and the sociodemographic characteristics of the intervened population. Main objective: to determine the frequency of postoperative tympanic perforations early (three months) and late (six months), in patients who underwent type I tympanoplasty in the ENT department of the San Rafael Clinical University Hospital in Bogotá, Colombia, during the years 2014 to 2019. Materials and methods: a retrospective, descriptive and cross-sectional study, that included adult and pediatric patients of the otolaryngology service of the San Rafael Clinical University Hospital of Bogotá, Colombia, with a history of tympanic perforations during the years 2014 to 2019 and who were operated with type I tympanoplasty were evaluated. Post-surgical results were evaluated. mainly the post-surgery perforations with "over-under" medial technique using ear cartilage graft and temporal fascia. Results: 47 patients were included in the study, of which 62% were female and 91% were older than 7 years. The percentage of reperforation was 8.5%, that is, 4 of 47 patients, and at 12.8 months on average. The most frequent cause of tympanic perforation was infectious with 66% and medium size 55.3%. The most frequent otolaryngological comorbidity was chronic otitis media with 51%. The audiological results showed a gain of 17% in the right ear and 20% in the left ear. Conclusions: Type I tympanoplasty with over under technique is considered successful for the anatomical closure of the tympanic perforations, evaluated at 3 and 6 months postoperatively, with percentages that are equal to those reported in similar studies in the literature. The audiometric results did not show a statistically significant improvement in both ears, so studies should continue to evaluate other factors associated with perforations such as chronic otitis media and cholesteatoma, among others.

RESUMEN Fundamento: la otitis media crónica es causa importante de morbilidad, deterioro auditivo e ingresos hospitalarios debido a recurrencias y complicaciones, donde la mastoidectomía radical modificada la técnica adecuada para lograr resultados anatómicos y funcionales. Objetivo: describir los resultados de la mastoidectomía radical modificada en pacientes con otitis media crónica supurada. Métodos: se realizó un estudio descriptivo retrospectivo, longitudinal en 54 pacientes con otitis media crónica, a los que se les realizó mastoidectomía radical modificada. Las variables objeto de estudio fueron de caracterización clínica y epidemiológica y los resultados se evaluaron en excelente, bueno, regular y malo. Los datos fueron procesados utilizando la estadística descriptiva para distribución de frecuencias absolutas y relativas, y se reflejaron en tablas. Resultados: el mayor número de operados fue del sexo masculino, entre la tercera y cuarta década de la vida; la hipoacusia, otorrea y perforación timpánica fueron las manifestaciones más frecuentes. La imagen tumoral e hipoacusia conductiva y la Pseudomona aeruginosa, se hallaron con mayor frecuencia. La mastoidectomía con timpanoplastia tipo III por lisis de los huesecillos, cavidades limpias, amplias, muros bajos e injerto íntegro, permitió que la mayoría de los pacientes tuvieran buenos resultados anatómicos y funcionales, y las complicaciones fueron escasas. Conclusiones: la técnica utilizada fue la mastoidectomía radical modificada, asociada a timpanoplastia tipo III y predominaron los resultados excelentes, buenos y regulares en los enfermos operados.

ABSTRACT Background: chronic media otitis is an important cause of morbidity, hearing impairment and hospital admissions due to recurrences and complications, with modified radical mastoidectomy being the appropriate technique to achieve anatomical and functional results. Objective: to describe the results of the modified radical mastoidectomy in patients with suppurative chronic media otitis. Methods: a retrospective, longitudinal descriptive study in 54 patients with chronic media otitis, who underwent modified radical mastoidectomy. The variables under study were of clinical and epidemiological characterization and the results were evaluated as excellent, good, fair and bad. The data were processed using descriptive statistics for distribution of absolute and relative frequencies, and were reflected in tables. Results: the largest number of patients was male, between the third and fourth decade of life; hearing loss, otorrhea and tympanic perforation were the most frequent manifestations. The tumor image and conductive hearing loss and Pseudomonas aeruginosa were found more frequently. The mastoidectomy with tympanoplasty type III by lysis of the ossicles, clean, wide cavities, low walls and intact graft, allowed the majority of patients to have good anatomical and functional results, and complications were scarce. Conclusions: the technique used was modified radical mastoidectomy, associated with tympanoplasty type III and excellent, good and regular results prevailed in the operated patients.
