ABSTRACT
Abstract Objectives When air irrigation is used for caloric stimulation in patients with a perforated ear, warm irrigation may elicit a nystagmus that initially beats in the opposite direction of what is expected for warm irrigations, which is referred to as "caloric inversion". This study aimed to investigate the disease group in which caloric inversion appeared in patients who underwent caloric testing and to classify the patterns of caloric inversion. Methods We conducted a retrospective review of bithermal caloric test results that were collected in our dizziness clinic between 2005 and 2022. Caloric inversion was defined when nystagmus induced by caloric stimulation appeared in the opposite direction to that expected. The incidence of caloric inversion among all patients who underwent bithermal caloric tests was calculated. To confirm the clinical diagnoses of the patients with caloric inversion, their clinical records were reviewed. Results Out of 9923 patients who underwent bithermal caloric tests, 29 patients (0.29%) showed a caloric inversion. The most common clinical diagnosis was chronic otitis media (21 of 29, 72%). Of the 21 patients with chronic otitis media, 20 patients showed a caloric inversion by warm air irrigation and one patient showed caloric inversion by cold air stimulation. Patients with clinical diagnoses other than chronic otitis media such as sudden sensorineural hearing loss, benign paroxysmal vertigo of childhood and recurrent vestibulopathy showed caloric inversion by warm air irrigation. Caloric inversion by warm water irrigation was observed in patients with lateral semicircular canal cupulopathy and recurrent vestibulopathy. Two patients (one with Meniere's disease and one with age-related dizziness) showed caloric inversion by cold water irrigation. Conclusion Caloric inversion can be observed in various diseases other than chronic otitis media with tympanic membrane perforation. Special care should be taken in the interpretation of caloric test results. Level of Evidence: Level 4.
ABSTRACT
Introducción: Existe gran controversia acerca de los signos radiológicos de la patología de oído medio y su relación con la extensión real de la patología que nos sugiera decidir un comportamiento determinado. Objetivo: establecer la concordancia entre los hallazgos radiológicos y quirúrgicos encontrados en pacientes sometidos a mastoidectomía. Material y Método: Diseño observacional descriptivo de corte transversal de prueba diagnóstica. Se revisó fichas clínicas y se especificó el tipo de cirugía junto con los hallazgos intra-quirúrgicos. Resultados: se observó erosión de la cadena osicular intraoperatoria en 75 pacientes, 63 predichos correctamente por tomografía computada (TC), con sensibilidad del 84% y especificidad del 94% (k = 0,625). Se detectó erosión del tegmen tympani en nueve pacientes por TC de los 10, con un VPP = 90% y un VPN = 95% (k = 0,809). Hubo sospecha de erosión del canal semicircular lateral en cinco pacientes y se encontró dehiscencias intraoperatorias en 12, sin falsos positivos (k = 0,554). La TC detectó dehiscencia del canal del nervio facial con sensibilidad del 55% y especificidad del 98% (k = 0,636). Conclusión: Los resultados sugieren que la TC preoperatoria con evidencia radiológica de erosión osicular tiene una buena a muy buena concordancia con los hallazgos intraoperatorios.
Introduction: There is a great controversy about the radiological signs of middle ear pathology and its relation with the real extension of the pathology that suggests us to decide a certain medical choice. Aim: To establish concordance between radiological and surgical findings in patients submitted to mastoidectomy. Material and Method: An observational and descriptive design of retrospective cross-sectional diagnostic test. Clinical records were reviewed to specify the type of surgery and intraoperative findings. Results: Intraoperative ossicular chain erosion was observed in 75 patients, 63 were correctly predicted by computed tomography (CT), with a sensitivity of 84% and specificity of 94% (k = 0.625). Tegmen tympani erosion was detected by CT in 9 patients out of 10, with a PPV = 90% and NPV = 95% (k = 0.809). There was suspected lateral semicircular canal erosion in 5 patients and intraoperative dehiscence was found in 12, with no false positives (k = 0.554). CT detected facial nerve canal dehiscence with sensitivity of 55% and specificity of 98% (k = 0.636). Conclusion: The results suggest that preoperative CT with radiological evidence of ossicular erosion has good to very good agreement with intraoperative findings.

Abstract Introduction Cholesteatoma is a disease with significant clinical impact but is incompletely understood. The challenge of performing studies with long-term follow-up in humans is a factor that has restricted the advance of knowledge in this field. Thus, the use of animal models is highly pertinent, and the Mongolian gerbil model has emerged as one of the most useful. Objective The present study aims to evaluate, through serial otoendoscopies, the development and characteristics of pars flaccida retraction pocket and cholesteatoma in Mongolian gerbils after obliteration of the eustachian tube and compare it with the control group. Methods Forty Mongolian gerbils were divided into two groups of 20 animals each. In the intervention group, the animals were followed with serial otoendoscopies after eustachian tube obliteration. In the control group, the animals were only followed through serial otoendoscopies. Results At the end of the 16-week follow-up, cholesteatoma was present in 13 of 38 (34.2%) ears in the intervention group, and in 7 of 34 (20.6%) in the control group (p = 0.197). When we considered cholesteatoma and its potential precursor, pars flaccida retraction pocket, in a combined way, we verified it in 23 of 38 (60.8%) in the intervention group and in 11 of 34 (32.3%) in the control group (p = 0.016). Conclusions Over the 16 weeks of follow-up, serial otoendoscopies enabled us to evaluate the formation and development of pars flaccida retraction pockets and cholesteatomas in Mongolian gerbils and proved to be an excellent diagnostic tool.

Abstract Introduction The role of elastin in tympanic retractions and chronic otitis media is not well established. Williams Syndrome (WS), a pathology related to a mutation in the elastin gene, could generate tympanic retractions. Objective To compare the prevalence of tympanic retractions among patients with WS and controls. Methods WS patients (n= 43 ears) and controls (n= 130 ears) were evaluated by digital otoscopic examination and the degree of tympanic membrane retraction was classified by 2 blinded experienced otolaryngologists. Results The agreement rate between the evaluators was 71.1% for pars tensa and 65% for pars flaccida retraction (p< 0.001). The pars tensa and pars flaccida retractions are present in patients with WS after an adjusted residue of respectively - 2.8 and - 2.6 (p= 0.011 and p= 0.022) compared with controls. Conclusions Tympanic membrane retractions are not more common in the WS group when compared with controls.

Conclusión: No se obtuvieron diferencias estadísticamente significativas entre los resultados anatómicos y funcionales comparando el uso de injerto FMT y CT para el tratamiento quirúrgico de la OMC simple con miringoplastía.
Abstract Introduction: Simple chronic otitis media (COM) is a common pathology in our population, and it is currently unclear, which grafts technique and material gives the best results. Aim: To determine if there are differences in the anatomical and functional results, when using temporal muscle fascia (FMT) or tragus cartilage graft (CT) in patients with COM who underwent myringoplasty at the Barros Luco Trudeau Hospital. Material and Method: Retrospective analytical cohort study of data obtained from clinical records. Results: Of 227 medical records, 154 met inclusion criteria. FMT was used in 102 patients (66%) and CT in 52 patients (34%). With FMT, 38 had reperforation (37%) and 41 had functional success (40%). With CT 18 had reperforation (35%) and 22 had functional success (42%). 38 patients had a history of active smoking and 53% of them presented reperforation, while of those without a history of smoking only 31%, this difference being statistically significant (p < 0,05). Conclusion: No statistically significant differences were obtained when analyzing the anatomical and functional results comparing the use of FMT and CT graft, for the simple surgical treatment of COM with myringoplasty.
ABSTRACT
Abstract Introduction The prevalence of middle ear disease and its risk factors have been the subject of multiple studies. High prevalence of middle ear disease has been described among North American natives, especially chronic otitis media. Such studies have not been carried out in South America. Objective To describe the prevalence of middle ear pathology and risk factors in native schoolchildren from southern Chile who belong to the Mapuche ethnic group, as well as the impact of socio-economic and demographic changes after 14 years of development. Material and methods Two otologic evaluations with an interval of 14 years were performed in schoolchildren with a percentage of indigenous population above 85%. Socioeconomic and demographic data were collected from national official statistical data. Results A total of 1067 schoolchildren were examined. Many described risk factors for ear pathology were found. An overall prevalence of 0.19% for tympanic membrane perforation, 5.6% for pars tensa retraction pockets, 1.5% for pars flaccida retraction pockets and 11.1% of otitis media with effusion was found. There were several socioeconomic improvements after 14 years. The difference between the prevalence of symptoms and the presence of otitis media with effusion was statistically significant (p < 0.001). Conclusions Despite the presence of several risk factors for middle ear disease, this study population showed a low prevalence of middle ear disease. The ethnic-racial factor seems to be a protective factor.
Resumo Introdução A prevalência de doenças da orelha média e seus fatores de risco já foram objeto de múltiplos estudos. A alta prevalência dessas doenças foi descrita entre os nativos da América do Norte, principalmente a otite média crônica. Tais estudos não foram feitos na América do Sul. Objetivo Descrever a prevalência de doenças da orelha média e fatores de risco em crianças de idade escolar, nativos do sul do Chile pertencentes à etnia Mapuche, bem como o impacto de mudanças socioeconômicas e demográficas após 14 anos de desenvolvimento. Método Foram feitas duas avaliações otológicas com intervalo de 14 anos em escolares com percentual da população indígena acima de 85%. Dados socioeconômicos e demográficos foram coletados a partir de dados estatísticos oficiais nacionais. Resultados Foram examinados 1.067 escolares. Foram encontrados diversos fatores de risco descritos para doença otológica. Foi encontrada uma prevalência geral de 0,19% para perfuração da membrana timpânica, 5,6% para retrações da pars tensa, 1,5% para retração da pars flácida e 11,1% de otite média com efusão. Houve várias melhorias socioeconômicas após 14 anos. A diferença entre a prevalência de sintomas e a presença de otite média com efusão foi estatisticamente significante (p < 0,001). Conclusões Apesar da presença de vários fatores de risco para doença da orelha média, a população estudada apresentou baixa prevalência da doença. O fator étnico parece ser protetor.

La actinomicosis es una infección causada por un bacilo anaerobio Gram-positivo, filamentoso, ramificado, no esporulado. Integra la flora habitual de la orofaringe y coloniza transitoriamente el tracto gastrointestinal, genital femenino y el árbol bronquial. Es poco frecuente en el hueso temporal. Por su semejanza a un hongo, es difícil su reconocimiento, lo que hace necesaria la sospecha clínica para obtener los cultivos apropiados en condiciones anaeróbicas en forma prolongada. Los hallazgos microscópicos típicos incluyen necrosis con gránulos de azufre amarillento y la presencia de filamentos que se asemejan a infecciones fúngicas. El tratamiento requiere de elevadas y prolongadas dosis de antibiótico con penicilina o amoxicilina, entre 6 y 12 meses. La duración de la terapia antimicrobiana podría ser reducida en pacientes que han sido operados quirúrgicamente. Se presenta, a continuación, un caso clínico de actinomicosis en el hueso temporal en un paciente pediátrico que requirió tratamiento quirúrgico para su resolución.
Actinomycosis is an infection caused by a Gram-positive, filamentous anaerobic bacillus. Mainly belonging to the human commensal flora of the oropharynx, it normally colonizes the human digestive and genital tracts and the bronchial tree. It is slightly frequent in the temporal bone. Bacterial cultures and pathology are the cornerstone of diagnosis, but particular conditions are required in order to get the correct diagnosis. Prolonged bacterial cultures in anaerobic conditions are necessary to identify the bacterium and typical microscopic findings include necrosis with yellowish sulfur granules and filamentous Gram-positive fungal-like pathogens. Patients with actinomycosis require prolonged (6- to 12-month) high doses of penicillin G or amoxicillin, but the duration of antimicrobial therapy could probably be shortened in patients in whom optimal surgical resection of infected tissues has been performed. A pediatric patient with actinomycosis in temporal bone who needed surgery resolution is reported.

Abstract Introduction Chronic otitis media (COM) with a central perforation or a concomitant cholesteatoma are both inflammatory lesions, however, with different etiologies. Both entities may present with an intact chain, and the final reconstruction is quite similar. Does it also apply for the hearing outcome? Objectives In a retrospective analysis, we investigated the preoperative hearing and the final hearing outcome of two groups of patients: those with COM and those with cholesteatoma, and compared various factors. Methods Patients operated between 2010 and 2019 were entered prospectively into a research database, and the integrity of the ossicular chain, the extent of the cholesteatoma, and the findings on computed tomography (CT) scans were retrospectively analyzed and correlated to the final hearing outcome. Results Out of 210 tympanoplasties for COM, 162 (80%) presented with an intact chain, and 85 (40%) ears could be analyzed. Out of 283 cholesteatoma surgeries, 53 (19%) ears presented with an intact chain. The preoperative air-bone gap (ABG) was worse in the COM group, but the postoperative ABG over the frequencies of 0.5 kHz and 4 kHz was the same (10 dB to 12 dB) in both groups, and remained within 20 dB in 90% (40 and 78 patients, respectively). The extension of the disease was rather limited in the cholesteatoma group (stages Ch1a and 1b), and better pneumatization and ventilation were beneficial for a good result. Postoperatively, the frequency of 4 kHz had the largest ABG (14 dB and 18 dB). Conclusion Overall, 80% of the patients with COM and less than 20% of those with cholesteatoma had an intact and mobile chain at surgery. Using equivalent surgical techniques for the tympanoplasty, the final outcome was almost the same for both groups, with a mean ABG of 10 dB to 12 dB.
ABSTRACT
Resumen La otitis media crónica colesteatomatosa (OMCC) complicada es una condición inusual en la época actual. Clásicamente las complicaciones se han clasificado en extracraneales e intracraneales. Estas últimas suponen un alto riesgo para los pacientes debido a la alta morbimortalidad y las secuelas neurológicas asociadas. La atención médica oportuna y derivación a otorrinolaringología junto con las medidas preventivas en edad pediátrica han disminuido la incidencia de los colesteatomas y sus complicaciones. Se presenta a continuación el caso de una paciente de 50 años, atendida en el Hospital Guillermo Grant Benavente de Concepción (Chile) por cuadro de OMCC complicada con meningoencefalitis y vasculitis infecciosa sin consulta precoz por contexto de pandemia COVID-19. Se expone metodología diagnóstica y manejo terapéutico.
Abstract Complicated chronic cholesteatomatous media otitis (CCMO) is an unusual condition nowadays. Complications have traditionally been classified as extracranial and intracranial. The last one entails a higher risk for patients due to high morbi-mortality and neurological consequences associated. Suitable medical care and otorhinolaryngological attention among with preventive measures in pediatric age have decreased the incidence of cholesteatomas and their complications. The following, is the case of a 50-year-old patient treated for CCMO at Guillermo Grant Benavente Hospital in Concepcion (Chile) complicated due to meningoencephalitis and infectious vasculitis without early diagnose due to COVID-19 pandemic. Diagnostic methodology and therapeutic management are exposed.
ABSTRACT
Objective@#To evaluate the preliminary surgical results of Endoscopic Type I Tympanoplasty among patients with inactive chronic otitis media without ossicular pathology. @*Methods@#Design: Prospective Series. Setting: Tertiary Government Hospital. @*Participants@#Seventy patients with inactive mucosal chronic otitis media (COM) with air bone gap (ABG) of ≤ 40 dB on the preoperative audiogram scheduled to undergo Type I Tympanoplasty between July 2018 and December 2020 were enrolled. @*Results@#Seventy-three (73) ears were evaluated. The overall rate of graft uptake was 95.9% at 12 weeks. There was a statistically significant (p<.001) improvement in hearing on comparison of pre-operative (25.74 ± 7.34 dB) and post-operative (14.82 ± 6.55 dB) air bone gap. The duration of surgery was less than one hour in 76.7% and 77.2 % patients experienced only mild post[1]operative pain. @*Conclusion@#Endoscopic tympanoplasty can provide good results with respect to graft uptake and hearing gain with short surgical duration and minimum postoperative morbidity. Longer follow up of at least 6 months (for graft uptake) and preferably not less than 12 months (for hearing results) may confirm our preliminary findings.

Abstract Introduction The surgical outcome of chronic otitis media (COM) of the mucosal type in the pediatric population with high rates of recurrent tympanic membrane perforation is indeed a concern for the attending surgeon. Objective The present study was done to evaluate the outcome of tympanoplasty in children with chronic otitis media mucosal type. Methods A retrospective analysis of the medical records of all children, aged < 16 years old, who underwent tympanoplasty for COM of the mucosal type was performed. These patients were addressed by a three-point assessment, for predicting outcome of tympanoplasty, which included the age of the patient, addressing the nasal/pharyngeal issues, and the status of the COM (discharging or dry). Surgical success was assessed in terms of graft uptake and improvement of hearing. Factors affecting the surgical outcome were also analyzed. Results A total of 90 children underwent type 1 tympanoplasty; 7 were lost to follow-up and 10 had incomplete audiometric results. In the 73 tympanoplasties analyzed, graft uptake was seen in 91.7% of the patients. Children with longer duration of ear discharge (> 8 years) had greater hearing loss. Children aged > 8 years old showed statistically significant higher chance of graft uptake (p = 0.021). Five of the six children who had graft rejection had bilateral disease. Conclusion A three-point assessment in the management of pediatric COM of the mucosal type offers good outcomes with post-tympanoplasty graft uptake rates > 90%.
ABSTRACT
Background: Chronic otitis media can be associated with various extracranial and intracranial complications. It has led to rise in number of people living with discharging ear and reduced hearing.Methods: Authors have shared their 3 years’ experience of a single tertiary institute regarding disease burden and management and results. This is a retrospective study including 500 cases of mucosal type of chronic otitis media and underwent tympanoplasty at the study institute. Follow-up records were kept for at least 6 months.Results: Graft uptake rate after 6 months follow-up was 86.2%. Cartilage tympanoplasty was performed for revision cases and had good results. Average air-bone gap closure was 17 dB. It is a simple surgery which can be performed in day care OT without any significant intra-op or post-op complication.Conclusions: Surgical treatment is significantly useful to reduce the disease burden due to chronic otitis media.
ABSTRACT
Abstract Introduction The goal of ossiculoplasty is to improve hearing and the success of this procedure depends on several factors. Objective Analyze the hearing results in patients with chronic otitis media undergoing ossicular chain reconstruction, as well as predictive factors for successful surgery. Methods Charts of patients undergoing ossiculoplasty between 2006 and 2016 were reviewed. Sixty-eight patients were included, totaling 72 ears. The following data was analyzed: gender, age, smoking status, laterality, pathology, audiometric exams, type of surgery, previous surgery, characteristics of the middle ear, otorrhea and ossicular chain status. Patients were also classified according to two indices: middle ear risk index and ossiculoplasty outcome parameter staging. The results were evaluated by comparing the air-bone gap before and after surgery. The success of reconstruction was defined as air-bone gap ≤20 dB and the improvement of speech reception Thresholds, calculated through the mean frequencies 0.5, 1, 2 and 3 kHz. Results Reconstruction success rate was 61%. The mean preoperative air bone gap was 34.63 dB and decreased to 17.26 dB after surgery. There was a correlation between low risk in middle ear risk index and ossiculoplasty outcome parameter staging indices with postoperative success. The most frequently eroded ossicle was the incus and the type of prosthesis most used was tragal cartilage. In the patients without incus, we achieved success in 74.2% of the surgeries. In the absence of the stapes, the success rate decreased to 63.3%. In the absence of the malleus, 85% of the patients had and air bone gap ≤20 dB. Conclusion We achieved good audiometric outcomes in ossiculoplasty and the results are comparable to other centers. Ossicle status influenced postoperative results, especially in the presence of stapes. We also concluded that the indexes analyzed may help to predict the success of the surgery.
Resumo Introdução A ossiculoplastia tem como objetivo a melhoria da audição e o sucesso desse procedimento depende de diversos fatores. Objetivo Analisar os resultados auditivos em pacientes com otite média crônica submetidos a reconstrução da cadeia ossicular, bem como os fatores preditivos de sucesso cirúrgico. Método Prontuários de pacientes submetidos a ossiculoplastia entre 2006 e 2016 foram revistos. Sessenta e oito pacientes foram incluídos, total de 72 orelhas. Os seguintes dados foram analisados: sexo, idade, tabagismo, lateralidade, doença, exames audiométricos, tipo de cirurgia, cirurgia prévia, características da orelha média, otorreia e estado da cadeia ossicular. Os pacientes também foram classificados de acordo com dois índices: índice de risco da orelha média e estadiamento do parâmetro de desfecho da ossiculoplastia. Os resultados foram avaliados comparando o gap aéreo-ósseo antes e após a cirurgia. O sucesso da reconstrução foi definido como gap aéreo-ósseo ≤ 20 dB e a melhoria dos limiares de recepção de fala, calculados pelas frequências médias de 0,5, 1, 2 e 3 kHz. Resultados A taxa de sucesso da reconstrução foi de 61%. O gap aéreo-ósseo pré-operatório médio foi de 34,63 dB e diminuiu para 17,26 dB após a cirurgia. Houve correlação entre baixo risco no índice de risco para orelha média e os índices de estadiamento do parâmetro de desfecho da ossiculoplastia com sucesso pós-operatório. O ossículo com erosão mais frequente foi a bigorna e o tipo de prótese mais utilizada foi a cartilagem tragal. Nos pacientes sem bigorna o sucesso foi alcançado em 74,2% das cirurgias. Na ausência do estribo, a taxa de sucesso diminuiu para 63,3%. Na ausência do martelo, 85% dos pacientes apresentaram gap aéreo-ósseo ≤ 20 dB. Conclusão Melhora significativa da audição foi observada em pacientes submetidos à ossiculoplastia, os resultados foram comparáveis aos de outros centros. O "status" dos ossículos influenciou os resultados pós-operatórios, principalmente a presença do estribo. Também concluímos que os índices analisados podem ajudar a prever o sucesso da cirurgia.

Aims and Objectives: This observational study is intended to identify the effectiveness of individual approach for each patient instead of a universal law of either Tympanoplasty alone or Cortical mastoidectomy with Tympanoplasty as a treatment for COM – mucosal type. Materials and Methods: This study comprises 100 consecutive patients who underwent surgery for the treatment of COM Mucosal type. We graded the Middle ear mucosa into six grades. All patients were followed up for a minimum of six months post operatively. Results:The graft uptake in our study was found to be 96% at the end of 6 months. Conclusion:Aconcomitant Mastoidectomy adds cost, surgical time and hospital stay to the patient among other things. However, Mastoidectomy should be done when there is evidence to suggest involvement of the mastoid compartment by the disease. The middle ear mucosa gives an indication of the disease status.
ABSTRACT
Chronic otitis media is a common disease of the developing world with persistent ear discharge, leading to major complications. This study describes the microorganisms isolated from the middle ear and nasopharynx of children with chronically discharging ears. Middle ear and nasopharyngeal swabs from 89 children were studied, and the microorganisms isolated were assessed for biofilm-forming ability. Methicillin-susceptible Staphylococcus aureus was common in the nasopharynx, while the middle ear showed predominantly pseudomonas and Methicillin-resistant S. aureus. Pseudomonas aeruginosa showed strong biofilm formation, whereas Escherichia coli, Proteus sp. and Providentia sp. were weak biofilm producers. S. aureus isolates were negative for biofilm formation.
ABSTRACT
Objective: The aim of the study was to study the effect of common comorbidities on the success rate of myringoplasty.Materials and Methods: A retrospective evaluation of the 40 patients who have undergone myringoplasty for different sizes ofcentral perforation with pure conductive hearing loss of <60 dB were done. Both males and females of age 15–60 years wereincluded in the study. The comorbidities studied were hypertension, diabetes and nasal allergy. Temporalis fascia was usedas the graft and grafting was done by underlay technique. Patients were followed up for 6 months. The influence of variouscomorbidities was assessed by comparing the rates of graft take up and graft retraction.Results: Among the 40 patients we selected, the majority were in the age group of 30–45 years. We had 7 (17.5%) patients withdiabetes mellitus and during the follow-up at 6 months, 28.6% of failure and 14.3% of retractions were observed. (significance?)Among the 9 (22.5%) patients who were hypertensives, we did not find any graft failure. 17 (42.5%) patients had a nasal allergy.We found failures in 23.5% by 6th month and retractions in 17.6%. P value was calculated and was found to be statistically notsignificant.
ABSTRACT
AIM: To study the clinical, radiological and operative findings in childhood acquired cholesteatoma. Methods: Totally 50 patients of age less than 18 years with active squamosal chronic otitis media (COM) underwent thorough clinical examination and pre-operative high resolution computed tomography (HRCT) of temporal bone followed by surgery. Their clinical examination findings, HRCT temporal findings and operative findings were noted and correlated. Results: According to the present study, commonest age group was 11-15 years, average duration of complaints was 7.9 years, commonest complaint was ear discharge, commonest examination finding was central perforation in tympanic membrane (TM), most patients had moderate conductive hearing loss, on HRCT temporal bone most common finding was soft tissue attenuation in middle ear cavity, per-operatively cholesteatoma was found in middle ear cleft in all the cases. Conclusion: Cholesteatoma is more aggressive especially in children where it has a short course of duration, high incidence of ossicular involvement and is more often associated with complications. High resolution computerized tomographic scan of temporal bone was highly accurate in diagnosing cholesteatoma, assessing the extent of the disease, identifying bony erosion and ossicular chain destruction and detecting destruction of lateral wall of mastoid, dural plate erosion and sinus plate erosion.

BACKGROUND AND OBJECTIVES: The Chronic Otitis Media Questionnaire-12 (COMQ-12) was developed in the United Kingdom to assess disease specific Health-Related Quality of Life (HRQoL) of chronic otitis media (COM) patients. We assessed the validity of Korean version of COMQ-12 (K-COMQ-12) and its correlation with the disease activity of COM classified according to the type of surgery. MATERIALS AND METHOD: We translated the original COMQ-12 into Korean and also performed a back-translation of the translated text into English. Enrolled were 106 COM patients and 106 healthy subjects. Cronbach alpha was used to evaluate internal consistency, and factor analysis was performed to prove reliability. We compared K-COMQ-12 scores between normal subjects and COM patients to assess validity. The scores were also compared by dividing groups according to disease activity of COM. RESULTS: Cronbach's alpha showed good internal consistency (0.939). There was a significant difference in K-COMQ-12 scores between healthy subjects (1.99±4.34) and COM patients (22.69±12.41). Also, scores go higher as the disease activity of COM increased. A cut-off score of 6 of K-COMQ-12 sets 0.915 of sensitivity and 0.934 of specificity. CONCLUSION: The K-COMQ-12 is a reliable and valid tool to assess HRQoL in patients with COM. The K-COMQ-12 could be also used as an objective tool that reflects the disease activity of COM.

Antecedentes. Cualquier paciente pediátrico o adulto que presente otitis media aguda (OMA) u otitis media crónica (OMC), particularmente colesteatomatosa, puede desarrollar complicaciones intratemporales y endocraneales, especialmente mastoiditis aguda (MA). Objetivo. Describir las características clínicas y bacteriología de los pacientes asistidos por MA como complicación de OMA y OMC. Lugar de aplicación: Servicio de Otorrinolaringología. Hospital de Pediatría Juan P. Garrahan. Diseño. Descriptivo, retrospectivo, transversal y observacional. Población. Pacientes con mastoiditis aguda por OMA y por OMC asistidos en el Servicio de ORL durante 10 años. Material y métodos. Revisión de historias clínicas de todos los pacientes tratados entre enero de 1999 y diciembre de 2008. Resultados. Se estudiaron 57 pacientes con MA, 40/57 por OMA y 17/57 por OMC. Hubo 40 niños hospitalizados con signos y síntomas de MA por OMA. Se diagnosticó complicación endocraneal en el 12,5% (5/40) de los casos. Los aislamientos bacterianos más frecuentes fueron Streptococcus pyogenes, Streptococcus pneumoniae, H. influenzae y Turicella otitidis. Se registraron 17 casos de niños hospitalizados con diagnóstico de MA y OMC. Ocurrieron complicaciones supurativas intracraneales en el 35,3% (6/17) de los casos. Los aislamientos bacterianos más frecuentes fueron las enterobacterias, P. aeruginosa y los gérmenes anaerobios. Conclusión. El diagnóstico de tipo y estadio de otitis media previa o coexistente a la complicación es fundamental para encarar el tratamiento antimicrobiano empírico inicial, sospechar complicaciones endocraneales asociadas y proponer procedimientos quirúrgicos menores, medianos o mayores oportunamente (AU)
Background. Any pediatric or adult patient presenting with acute otitis media (AOM) or chronic otitis media (COM), especially cholesteatomatous, may develop intratemporal and intracranial complications, mainly acute mastoiditis (AM). Objective. To describe the clinical and bacteriological features of patients seen for AM as a complication of AOM and COM. Setting: Department of Otolaryngology, Hospital de Pediatría Juan P. Garrahan. Design. A descriptive, retrospective, cross-sectional, observational study. Population. Patients with AM because of AOM and COM seen at the Department of Otolaryngology over a 10-year period. Material and methods. Review of the clinical charts of all patients treated between January 1999 and December 2008. Results. 57 Patients with AM, 40/57 due to AOM and 17/57 due to COM, were evaluated. Forty children were admitted to hospital with signs and symptoms of AOM-related AM. Intracranial complications were observed in 12.5% (5/40) of the patients. The most frequently isolated pathogens were Streptococcus pyogenes, Streptococcus pneumoniae, H. influenzae, and Turicella Otitidis. Seventeen children were hospitalized because of COM-related AM. Suppurative intracranial complications occurred in 35.3% (6/17) of the cases. The most frequently isolated pathogens were Enterobacteriaceae, P. aeruginosa, and anaerobic bacteria. Conclusion. The diagnosis of type and stage of otitis media prior to or coexisting with the complication is essential to address the initial empirical antimicrobial treatment, associated intracranial complications should be suspected and minor, intermediate, or major surgical procedures should be proposed at the appropriate time (AU)
