Olfactory rehabilitation and olfactory bulb volume changes in patients after total laryngectomy: a prospective randomized study / Reabilitação olfatória e alterações do volume do bulbo olfatório em pacientes pós-laringectomia total: um estudo prospectivo randomizado

Abstract Introduction: After total laryngectomy, decreased olfactory function and olfactory bulb volume shrinkage have been reported to occur due to olfactory deprivation caused by nasal airflow interruption. There is evidence that the olfactory system can be modulated by repeated exposure to odors in a procedure called olfactory training. However, it is not known whether any recovery of the lost olfactory bulb volume is possible by eliminating olfactory deprivation via olfactory rehabilitation long after laryngectomy. Objective: This study examined the recovery of olfactory function and the change in olfactory bulb volume via long-term olfactory rehabilitation after total laryngectomy. Methods: Possible causes of olfactory dysfunction in the study participants were evaluated by collecting detailed anamnesis. As olfactory tests, orthonasal butanol threshold and odor discrimination tests were performed. Three-dimensional olfactory bulb volumes were calculated using manual segmentation on T2-weighted coronal magnetic resonance images. In olfactory rehabilitation, four different odors were applied to all patients orthonasally, using a larynx bypass technique for 30 min per day for 6 months. Olfactory tests were performed before the rehabilitation and after 6 months of rehabilitation, and olfactory bulb volume measurements were performed using magnetic resonance images. Results: Eleven patients diagnosed with advanced laryngeal cancer who underwent total laryngectomy and postoperative radiotherapy with a follow-up of 5-10 years were included in the study. All patients were male, and the mean age was 58.18 ±4.17 years. In total laryngectomized patients, the olfactory bulb volumes measured on magnetic resonance images were 42.25 ± 12.8 mm3 before and 55.5 ± 11.22 mm3 after rehabilitation, and this increase was highly significant. Olfactory test scores were 2.3 ± 1.27 before and 4.39 ± 0.86 after rehabilitation, and this increase was also highly significant. Conclusion: As a result of the olfactory rehabilitation applied by providing orthonasal air flow, the olfactory function lost after total laryngectomy was improved considerably, and the olfactory bulb volume was significantly increased. The increase in olfactory bulb volume in total laryngectomy patients via olfactory rehabilitation to eliminate olfactory deprivation due to nasal airflow interruption was demonstrated for the first time in this prospective longitudinal study.

Resumo Introdução: Após a laringectomia total, foi relatada a ocorrência de diminuição da função olfatória e redução do volume do bulbo olfatório devido à privação olfatória causada pela interrupção do fluxo aéreo nasal. Há evidências de que o sistema olfatório pode ser modulado pela exposição repetida a odores em um procedimento denominado treinamento olfatório. Entretanto, não se sabe se qualquer grau de recuperação do volume perdido do bulbo olfatório é possível ao eliminar a privação olfatória através de reabilitação muito tempo depois da laringectomia. Objetivo: Este estudo avaliou a recuperação da função olfatória e a mudança no volume do bulbo olfatório através da reabilitação olfatória de longo prazo após a laringectomia total. Métodos: As possíveis causas de disfunção olfatória nos participantes do estudo foram avaliadas através da anamnese detalhada. Como testes olfatórios, foram feitos os testes de limiar de butanol ortonasal e de discriminação de odores. Os volumes tridimensionais do bulbo olfatório foram calculados com segmentação manual em imagens de ressonância magnética coronal ponderadas em T2. Na reabilitação olfatória, quatro odores diferentes foram aplicados a todos os pacientes ortonasalmente com uma técnica de bypass laríngeo por 30 minutos por dia durante 6 meses. Os testes olfatórios foram feitos antes da reabilitação e 6 meses após a reabilitação e as medidas do volume do bulbo olfatório foram feitas por imagens de ressonância magnética. Resultados: Foram incluídos no estudo 11 pacientes com diagnóstico de câncer de laringe avançado, submetidos à laringectomia total e radioterapia pós-operatória em um seguimento de 5 a 10 anos. Todos os pacientes eram do sexo masculino e a média de idade foi de 58,18 ± 4,17 anos. Em pacientes com laringectomia total, os volumes do bulbo olfatório medidos por imagens de ressonância magnética foram de 42,25 ± 12,8 mm3 antes e 55,5 ± 11,22 mm3 após a reabilitação e esse aumento foi altamente significante. Os escores dos testes olfatórios foram 2,3 ± 1,27 antes e 4,39 ± 0,86 após a reabilitação e esse aumento também foi altamente significante. Conclusão: Como resultado da reabilitação olfatória aplicada através do fornecimento de fluxo de ar ortonasal, a função olfatória perdida após a laringectomia total melhorou consideravelmente e o volume bulbo olfatório mostrou aumento significativo. O aumento no volume do bulbo olfatório em pacientes submetidos a laringectomia total através da reabilitação olfatória para eliminar a privação olfatória devido à interrupção do fluxo aéreo nasal foi demonstrado pela primeira vez neste estudo longitudinal prospectivo.

Voice rehabilitation with voice prosthesis: Long term results, complications and risk factors.

OBJECTIVES: Despite the advances in surgical and non-surgical organ preservation treatments, total laryngectomy (TL) remains the most effective treatment in advanced larynx cancer and as salvage procedure in chemoradiation failure. One of the most devastating sequel after TL is loss of voice. Voice prosthesis (VP) is currently the preferred choice for voice rehabilitation. The purpose of this study is to identify VP complications, its lifespan and factors that influence the longevity of the VP. METHODS: We performed a retrospective study at a Tertiary University Hospital. Medical records of patients that underwent total laryngectomy, between January 1st of 2008 and 31st of December of 2017 were analyzed. RESULTS: Of the 84 patients that underwent laryngectomy, 60 had VP. The average age at the time of surgery 60.2 years old and there was a male preponderance (57:3). The mean lifespan of the prosthesis was 7.53 months. Leakage through the prosthesis was the most common reason for replacement of the prosthesis, followed by leakage around the prosthesis. Follow up time and manual suture were associated with prosthesis replacement. There was no significant relationship between the staging, tumor location or adjuvant radiotherapy and number of prosthesis replacement or its lifespan. CONCLUSIONS: Rehabilitation after TL is of major importance to improve quality of life after surgery. Tracheoesophageal puncture with voice prosthesis is a safe procedure for vocal rehabilitation and was performed in the majority of patients in our study. Follow-up time and type of suture were the main determinants of the lifespan of the prosthesis.

Objetivos: A pesar de los avances en los tratamientos quirúrgicos y no quirúrgicos para la preservación de órganos, la laringectomía total (LT) sigue siendo el tratamiento más efectivo en el cáncer avanzado de laringe, y como procedimiento de rescate en caso de fallo de la radioquimioterapia.Una de las secuelas más devastadoras tras la LT es la pérdida de la voz. Las prótesis de voz (PV) son actualmente la elección preferida para la rehabilitación de la voz. El objetivo de este estudio es identificar las complicaciones de las PV, su vida útil y los factores que influyen en la longevidad de dichas prótesis.MétodosRealizamos un estudio retrospectivo en un hospital universitario terciario, en el que se analizaron los registros médicos de los pacientes sometidos a laringectomía total entre el 1 de enero de 2008 y el 31 de diciembre de 2017.ResultadosDe los 84 pacientes sometidos a laringectomía, 60 tenían PV. La edad media en el momento de la cirugía fue de 60,2 años, y hubo una preponderancia de varones (57:3).La vida útil media de las prótesis fue de 7,53 meses. La fuga a través de la prótesis fue el motivo más común de su sustitución, seguida de la fuga alrededor del dispositivo.El tiempo de seguimiento y la sutura manual estuvieron asociados a la sustitución de la prótesis. No existió una relación significativa entre la estadificación, la localización del tumor o la radioterapia adyuvante y el número de sustituciones de prótesis o su vida útil.ConclusionesLa rehabilitación tras la LT es de gran importancia para mejorar la calidad de vida tras la cirugía. La punción traqueoesofágica con prótesis de voz es un procedimiento seguro para la rehabilitación de la voz, habiéndose realizado en la mayoría de los pacientes de nuestro estudio.El tiempo de seguimiento y el tipo de sutura fueron los principales determinantes de la vida útil de las prótesis.

Análisis de factores predictivos en la aparición de fístulas faringocutáneas poslaringectomía total / Analysis or predictive factors associated with pharingocutaneous fistulas after total laryngectomy

RESUMEN Antecedentes: la fístula faringocutánea es la complicación más común luego de una laringectomía total. Los factores implicados en su aparición son estudiados por numerosos autores sin obtener resultados concluyentes. Objetivo: Evaluar las causas de aparición de fístula faringocutánea y describir los factores de riesgo implicados en la aparición de fístulas faringocutáneas en la población estudiada. Material y métodos: estudio retrospectivo, observacional, con análisis estadístico de variables. Se consideraron 55 pacientes a quienes se les realizó una laringectomía total inicialmente o como rescate, desde enero de 2000 hasta diciembre de 2019, con una proporción hombre/mujer de 48/7. La edad media fue de 61,3 años. El 96,36% con diagnóstico anatomopatológico de carcinoma epidermoide. Análisis estadístico (prueba de chi cuadrado-prueba de Mann-Whitney) de variables relacionadas con la aparición de fístula faringocutánea. Resultados: la incidencia de fístulas alcanzó el 20% de los pacientes laringectomizados. Cerraron espontáneamente el 72,73% de las fístulas y requirieron el uso de colgajos, 3 (27,27%) pacientes. De los pacientes fistulizados, el 63,64% tenían radioterapia previa. El uso de sonda nasogástrica para alimentación se prolongó en dichos pacientes por más de 15 días. El tiempo de internación promedio de los pacientes fistulizados fue de 23 días. Conclusión: en nuestro medio, el factor más asociado a la aparición de fístulas tras laringectomía fue el uso de radioterapia previa. La fístula en estos pacientes tardó más tiempo en cerrarse y requirió en algunos casos reconstrucciones más complejas.

ABSTRACT Background: Pharyngocutaneous fistula is the most common complication after total laryngectomy. The factors associated with its development have been studied by several authors without conclusive results. Objective: To evaluate the causes for the development of PCF and to describe the risk factors associated with PCF in the population studied. Material and methods: We conducted a retrospective and observational study with statistical analysis of the variables. A total of 55 patients undergoing initial or salvage total laryngectomy from January 2000 to December 2019 were included. Male-to-female ratio was 48/7. Mean age was 61.3 years. The pathological diagnosis was epidermoid carcinoma in 96.36% of the cases. Statistical analysis: (chi square test and Mann-Whitney test) of the variables related with the development of pharyngocutaneous fistula. Results: The incidence of fistula in patients with laryngectomy was 20%. Spontaneous closure occurred in 72.73% and 3 patients (27.27%) required the use of flaps. In patients with fistula, 63.64% had previous radiotherapy. In these patients, the use of nasogastric tube feeding lasted > 15 days. Mean length of hospital stay in patients with fistula with 23 days. Conclusion: In our environment, previous radiotherapy was the most significant factor associated with the development of fistula. In these patients, fistula took longer to close and required more complex reconstructions in some cases.

Rehabilitación olfatoria en pacientes laringectomizados: maniobra de inducción del flujo aéreo nasal / Olfactory rehabilitation in laryngectomized patients: nasal airflow inducing maneuver

Objetivo: Demostrar que la "maniobra de inducción del flujo aéreo nasal" (MIFAN) rehabilita el olfato en pacientes con LT. Material y Método: Estudio cuasiexperimental antes-después en pacientes laringectomizados por cáncer de laringe del Servicio de Otorrinolaringología del Hospital Barros Luco Trudeau (HBLT) de Santiago de Chile. Evaluación a través de encuesta, examen físico, nasofibroscopía y test olfatométrico. Pacientes con alteración del olfato por transmisión serán enrolados y se enseñará la MIFAN. Resultados: Se estudiaron 12 pacientes: 10 hombres, 2 mujeres. Edad promedio 66,3 años, todos autovalentes. 66,6% presentó anosmia y 33,3% hiposmia. Todos lograron realizar la maniobra. Posrehabilitación el 100% presentó presencia de olfato valorada por olfatometría. Población intervenida similar a otras series en cuanto a sexo y edad. La erigmofonación facilita la rehabilitación con MIFAN. La rehabilitación del olfato se logró en todos y paralelamente mejoró el sentido del gusto. Conclusión: La MIFAN es una técnica sencilla, barata y asequible para lograr rehabilitar el sentido del olfato en pacientes laringectomizados.

Abstract Introduction: Total laryngectomy (TL) has as a consequence the loss of voice, but another not studied consequence is the loss of smell. Aim: To demonstrate that the "nasal airflow inducing maneuver" (NAIM) rehabilitates smell in patients with TL. Material and Method: A quasi-experimental before-after study in laryngectomized patients for laryngeal cancer from the Otorhinolaryngology Service (ENT) of the Barros Luco Trudeau Hospital (BLTH) at Santiago, Chile. Evaluation through survey, physical examination, nasofibroscopy and olfactory test. Patients with transmission impairment of smell were enrolled and NAIM was performed. Results: 12 patients were studied: 10 men, 2 women. Average age 66.3 years. All self-supporting. 66.6% presented anosmia and 33.3% hyposmia. They all managed to perform the maneuver. Post-rehabilitation, 100% presented the presence of smell assessed by olfactometry. Intervened population similar to other series in terms of sex and age. Esophageal speech facilitates NAIM rehabilitation. Rehabilitation of smell was achieved in all of them and in parallel, the sense of taste improved. Conclusion: NAIM is a simple, cheap and affordable technique to rehabilitate the sense of smell in laryngectomized patients.

Comparación de sutura mecánica con sutura manual de la faringe en laringectomía total / Comparison of mechanical suture with manual suture of the pharynx in total laryngectomy

Introducción: La sutura mecánica es una opción para el cierre de la faringorrafia en laringectomía total por cáncer de laringe. Objetivo: Comparar el uso de sutura mecánica lineal con sutura manual de la faringe durante la laringectomía total por cáncer de laringe. Material y Método: Se realizó un estudio de tipo experimental prospectivo. Se compararon dos grupos pacientes: Los pacientes con sutura mecánica desde 2018 a marzo de 2020 y los pacientes con sutura manual previa a enero de 2018 en el Servicio de Otorrinolaringología del Hospital Barros Luco. Se analizaron fístula faringo-cutánea posoperatoria (FFC), tiempo operatorio, estadía hospitalaria y costo. Resultados: El estudio incluyó a 14 pacientes, cada grupo con n = 7. El grupo con sutura mecánica presento 0% de FFC y el grupo sutura manual 28%. El grupo con sutura mecánica reinicio alimentación a los 7 días y el grupo con sutura manual en promedio a los 11,5 (7-23) días. (p = 0,0023). El tiempo promedio de cirugía para el grupo experimental es de 288 ± 37,4 minutos y con sutura manual 311 ± 32,4 minutos. (p = 0,0176). El promedio de hospitalización para el grupo experimental fue de 11 ± 2,6 días (9 a 16), y para el grupo control fue de 21 ± 14 días (10 a 49) (p < 0,0001). Conclusión: La sutura mecánica es un procedimiento fácil de usar y seguro. Existiría un beneficio en el uso de sutura mecánica para el cierre faríngeo al compararlo con la sutura manual al disminuir el número de FFC, el tiempo operatorio y los días de hospitalización.

Introduction: Mechanical suture is an option for the closure of the pharyngorrhaphy in total laryngectomy due to laryngeal cancer. Aim: To compare the use of linear mechanical suture with manual pharyngeal suture during total laryngectomy for laryngeal cancer. Material and Method: A prospective experimental study was carried out. Two patient groups were compared: patients with mechanical suture from 2018 to March 2020 and patients with manual suture prior to January 2018 at the otorhinolaryngology service of the Barros Luco Hospital. Postoperative pharyngocutaneous fistula (FFC), operative time, hospital stay and cost were analyzed. Results: The study included 14 patients, each group with n = 7. The group with mechanical suture presented 0% of FFC and the group with manual suture 28%. The group with mechanical suture restarted feeding at 7 days and the group with manual suture on average at 11.5 (7-23) days (p = 0.0023). The average surgery time for the experimental group was 288 ± 37.4 minutes, while for the group with manual suture was 311 ± 32.4 minutes (p = 0.0176). The mean hospitalization for the experimental group was 11 ± 2.6 days (9 to 16), and for the control group it was 21 ± 14 days (10 to 49) (p < 0.0001). Conclusion: The mechanical suture is an easy to use and safe procedure. There would be a benefit in the use of mechanical suture for pharyngeal closure when buying it with manual suture by reducing the number of FFCs, operative time and days of hospitalization.

Comparison of Patients With Total and Salvage Laryngectomy.

INTRODUCTION AND OBJECTIVES: Total laryngectomy (TL) is one of the treatments available in locally advanced laryngeal carcinomas or as a salvage therapy when organ preservation fails, achieving high survival rates and few complications. The aim of this study was to analyse the oncological outcomes, comparing the data obtained with the current literature and analysing complications and survival. METHODS: The study included 62 patients with primary carcinoma of the larynx treated by primary or salvage TL between 2003 and 2019. We analysed the demographic, clinical and pathological characteristics, tumour stage, complementary treatments, postoperative complications, locoregional recurrences, metastases, and causes of death. RESULTS: The mean age was 64 years, 90.3% were men, 96.8% were smokers, 43.5% had multiple pathologies and 82.3% had a locally advanced stage. Of all TL 71% were primary and 29% salvage. Neck dissection was performed in 59.6%. Lymphovascular invasion was present in 30.6%, perineural invasion in 30.6% and margin involvement in 14.5%. During the follow-up, 17.7% presented locoregional recurrence and 11.3% distant metastases. Regarding complementary treatments, 56.4% of the patients received adjuvant therapy. The incidence of haemorrhage was 11.3%, infection 14.5%, and pharyngocutaneous fistula 21%. There was a statistically significant correlation between fistula and haemorrhage (P = .000) and between fistula and infection (P = .000). No statistically significant differences were found between the studied factors of primary and salvage TL. The 3-year overall survival was 92% and 5-year overall survival was 88%, finding statistical significance with the locally advanced stage (P = .038), T4 (P = .026), lymphovascular invasion (P = .019) and the involvement of more than 3 lymph nodes in the pathological anatomy (P = .005). On the multivariate analysis, the only variable that showed a significant relationship with survival was lymphovascular invasion (P = .026). CONCLUSIONS: Although organ preservation is a primary objective, TL remains a leading treatment in locally advanced carcinomas and as salvage in case of failure of medical therapy or partial surgery.

Preservación de órgano en pacientes con tumores avanzados de laringe. Resultados de la quimioterapia de inducción versus quimio-radioterapia en la práctica clínica real / Organ preservation in patients with advanced laryngeal tumours. Results of induction chemotherapy versus chemoradiotherapy in actual clinical practice

Introducción y objetivos: Un porcentaje elevado de pacientes con carcinomas localmente avanzados de laringe son candidatos a ser incluidos en protocolos de preservación de órgano. El objetivo del presente estudio es comparar los resultados de dos esquemas de preservación, quimioterapia de inducción versus quimio-radioterapia, en pacientes con carcinomas de laringe localmente avanzados en un contexto de práctica clínica real.MétodosEstudio retrospectivo realizado en 157 pacientes con tumores localmente avanzados de laringe (T3-T4) tratados con quimioterapia de inducción (n = 121) o quimio-radioterapia (n = 36).ResultadosDe los 121 pacientes que iniciaron tratamiento con quimioterapia de inducción, seis fallecieron como consecuencia de toxicidad, 37 fueron tratados con cirugía y 78 completaron el esquema de preservación; 36 pacientes recibieron un tratamiento inicial con quimio-radioterapia. No existieron diferencias significativas en la supervivencia específica a los cinco años en función de que los pacientes iniciasen un tratamiento con quimioterapia de inducción o quimio-radioterapia (68,9% versus 75,7%, p = 0,259). Un 45,9% de los pacientes consiguió una preservación de la función laríngea. Los pacientes tratados con quimio-radioterapia tuvieron una tendencia a conseguir una supervivencia libre de pérdida de la función laríngea a los cinco años superior a la de los pacientes tratados con quimioterapia de inducción (55,6% versus 44,8%, p = 0,079).ConclusiónLos pacientes incluidos en un protocolo de preservación consiguieron una supervivencia libre de disfunción laríngea a los cinco años del 45,9%.

Introduction and objectives: A high percentage of patients with locally advanced larynx carcinomas are candidates for inclusion in organ preservation protocols. The objective of this study is to compare the results of two schemes of preservation, induction chemotherapy versus chemoradiotherapy, in patients with locally advanced larynx carcinomas in the context of actual clinical practice.MethodsOur retrospective study included 157 patients with locally advanced tumours of the larynx (T3-T4) treated with induction chemotherapy (n = 121) or chemoradiotherapy (n = 36).ResultsFrom 121 patients who began treatment with induction chemotherapy, 6 died due to toxicity, 37 were treated with surgery, and 78 completed the preservation scheme; 36 patients received treatment with chemoradiotherapy. There were no significant differences in 5-year disease-specific survival between both treatments: 68.9% in induction chemotherapy versus 75.7% in chemoradiotherapy (p = 0.259). In 45.9% of patients the laryngeal function was preserved. Patients treated with chemoradiotherapy had a tendency to have better 5-year laryngeal dysfunction-free survival than patients treated with induction chemotherapy (55.6% versus 44.8%, p = 0.079).ConclusionPatients included in a protocol of organ preservation achieved a 5-year laryngeal dysfunction-free survival of 45.9%. There were no significant differences in disease-specific survival among patients treated with induction chemotherapy or chemoradiotherapy. (AU)

Neck dissection was performed in 59.6%. Lymphovascular invasion was present in 30.6%, perineural invasion in 30.6% and margin involvement in 14.5%. During the follow-up, 17.7% presented locoregional recurrence and 11.3% distant metastases. Regarding complementary treatments, 56.4% of the patients received adjuvant therapy. The incidence of haemorrhage was 11.3%, infection 14.5%, and pharyngocutaneous fistula 21%. There was a statistically significant correlation between fistula and haemorrhage (P=.000) and between fistula and infection (P=.000). No statistically significant differences were found between the studied factors of primary and salvage TL. The 3-year overall survival was 92% and 5-year overall survival was 88%, finding statistical significance with the locally advanced stage (P=.038), T4 (P=.026), lymphovascular invasion (P=.019) and the involvement of more than 3 lymph nodes in the pathological anatomy (P=.005). On the multivariate analysis, the only variable that showed a significant relationship with survival was lymphovascular invasion (P=.026). CONCLUSIONS: Although organ preservation is a primary objective, TL remains a leading treatment in locally advanced carcinomas and as salvage in case of failure of medical therapy or partial surgery.

Organ preservation in patients with advanced laryngeal tumours. Results of induction chemotherapy versus chemoradiotherapy in actual clinical practice. / Preservación de órgano en pacientes con tumores avanzados de laringe. Resultados de la quimioterapia de inducción versus quimio-radioterapia en la práctica clínica real.

INTRODUCTION AND OBJECTIVES: A high percentage of patients with locally advanced larynx carcinomas are candidates for inclusion in organ preservation protocols. The objective of this study is to compare the results of two schemes of preservation, induction chemotherapy versus chemoradiotherapy, in patients with locally advanced larynx carcinomas in the context of actual clinical practice. METHODS: Our retrospective study included 157 patients with locally advanced tumours of the larynx (T3-T4) treated with induction chemotherapy (n = 121) or chemoradiotherapy (n = 36). RESULTS: From 121 patients who began treatment with induction chemotherapy, 6 died due to toxicity, 37 were treated with surgery, and 78 completed the preservation scheme; 36 patients received treatment with chemoradiotherapy. There were no significant differences in 5-year disease-specific survival between both treatments: 68.9% in induction chemotherapy versus 75.7% in chemoradiotherapy (p = 0.259). In 45.9% of patients the laryngeal function was preserved. Patients treated with chemoradiotherapy had a tendency to have better 5-year laryngeal dysfunction-free survival than patients treated with induction chemotherapy (55.6% versus 44.8%, p = 0.079). CONCLUSION: Patients included in a protocol of organ preservation achieved a 5-year laryngeal dysfunction-free survival of 45.9%. There were no significant differences in disease-specific survival among patients treated with induction chemotherapy or chemoradiotherapy.

Biomecânica da língua durante a deglutição após laringectomia total: revisão integrativa / Biomechanics of the tongue during swallowing after total laryngectomy: an integrative review

RESUMO Objetivo Sintetizar o estado do conhecimento científico sobre biomecânica da língua durante a deglutição após laringectomia total. Estratégia de pesquisa Formulou-se a questão PICO e combinações de descritores e termos livres para busca nas bases de dados PubMed/Medline, EMBASE, LILACS e SciELO. Critérios de seleção incluíram-se artigos nos idiomas português, inglês ou espanhol; sem limite de tempo; com resultados sobre a biomecânica da língua durante a deglutição em laringectomizados totais; e estudos do tipo ensaio clínico randomizado ou não randomizado, coorte, caso controle, transversal, série de casos e estudos de caso. Análise dos dados analisou-se ano, país, população, objetivo, delineamento do estudo, instrumentos de avaliação, principais desfechos e qualidade metodológica. Resultados Foram incluídos quatro estudos realizados nos Estados Unidos, um na Austrália e um no Brasil, publicados entre 1986 e 2014. Em todos os estudos incluídos a biomecânica da língua foi um desfecho secundário. A maioria dos artigos teve baixa qualidade metodológica, com amostras pequenas, predomínio do sexo masculino e desenho transversal prevalente. Os instrumentos de avaliação foram videofluoroscopia, manometria, acelerômetro ou dispositivo para captar pressão de língua. Resultados principais indicaram mais força de propulsão da base de língua para superar a alta resistência da neofaringe ao fluxo do bolo alimentar; redução do contato e pressão entre base de língua e parede posterior da faringe; resíduo em base de língua após deglutição; pressão aumentada e resistência reduzida da língua oral. Conclusão Existem indícios de movimentos compensatórios de língua durante a deglutição após laringectomia total, porém, as evidências científicas são insuficientes.

ABSTRACT Purpose To synthesize the state of scientific knowledge about biomechanics of the tongue during swallowing after total laryngectomy. Research strategy The PICO question and combinations of descriptors and single terms were formulated in the PubMed/Medline, EMBASE, LILACS, and SciELO databases. Selection criteria Articles in Portuguese, English, or Spanish were included, without time limit, with results on the biomechanics of the tongue during swallowing and total laryngectomy, and studies on randomized or non-randomized clinical trials, cohort, case control, cross-sectional, case series, and case studies. Data analysis year, country, population, objective, study design, assessment methods, main outcomes, and methodological quality were analyzed. Results There were four studies in the United States, one in Australia, and one in Brazil, all published between 1986 and 2014. In all studies, the biomechanics of the tongue was the secondary outcome. Most articles had low methodological quality, small samples, predominance of the male gender, and a prevalent cross-sectional design. The assessment instruments were fluoroscopy, manometry, accelerometer or a device to capture tongue pressure. Main results indicated a higher propulsion force of the tongue base to overcome the high resistance of the neopharynx to the bolus flow, reduced contact and pressure between the base of the tongue and the posterior pharyngeal wall, residues in the tongue base after swallowing, increased pressure, and reduced resistance of the oral tongue. Conclusion There are indications of compensatory tongue movements during swallowing after total laryngectomy; however, the scientific evidence is insufficient.

Reconstrução atípica de laringe: avaliação funcional pós-laringectomia supratraqueal ampliada com cricoglossohioidopexia / Atypical reconstruction of the larynx: functional assessment after enlarged supratracheal laryngectomy with cricoglossohioidopexy

RESUMO Em tumores transglóticos estendidos para base de língua, a indicação para ressecção do osso hioide descarta a possibilidade de realização de uma laringectomia parcial horizontal clássica, devido ao grande risco de complicações pulmonares oriundas de uma disfagia grave. O objetivo deste estudo foi descrever os aspectos funcionais de deglutição e voz de um paciente submetido à laringectomia supratraqueal ampliada com cricoglossohioidopexia. Trata-se de um homem de 69 anos, com tumoração transglótica na hemilaringe direita, submetido à laringectomia supratraqueal ampliada, com ampliação para base de língua, osso hioide e aritenoide direita. Na videofluoroscopia da deglutição, observou-se aspiração silente para líquido fino durante a deglutição e resíduo em base de língua, valécula, aritenoide, esfíncter esofágico superior e recessos piriformes em todas as consistências e volumes. Na videolaringoscopia, observou-se voz por meio da vibração da unidade cricoaritenóidea esquerda, associada à base de língua e constritores da faringe. No protocolo Consensus Auditory-Perceptual Evaluation of Voice (CAPE V), notou-se grau moderado de rouquidão e soprosidade. O paciente apresentou preservação parcial das funções laríngeas, grau moderado de disfonia e alimentação e hidratação exclusivas por via oral, com sólidos macios e líquido espessado em néctar, sem prejuízos à saúde pulmonar, até o momento.

ABSTRACT In transglottic tumors extended to the base of the tongue, the indication for resection of the hyoid bone rules out the possibility of performing a classic horizontal partial laryngectomy due to the high risk of pulmonary complications resulting from severe dysphagia. This study aims to describe the functional aspects of swallowing and voice of a patient undergoing an enlarged supratracheal laryngectomy with cricoglossohioidopexy. This is a 69-year-old man with a transglottic tumor in the right hemilarynx, who underwent an extended supratracheal laryngectomy with enlargement to the base of the tongue, hyoid bone and right arytenoid. In swallowing videofluoroscopy, silent aspiration was observed in fine liquid and residue on the basis of tongue, valecule, arytenoid, upper esophageal sphincter and pyriform recesses in all consistencies and volumes. In videolaryngoscopy, a voice was observed through the vibration of the left cricoarytenoid unit associated with the base of the tongue and constrictors of the pharynx. The Consensus Auditory-Perceptual Evaluation of Voice (CAPE V) showed a moderate degree of hoarseness and breathiness. The patient had partial preservation of laryngeal functions, with a moderate degree of dysphonia and exclusive oral feeding and hydration with soft solids and thickened liquid in nectar without impairing lung health until the study.

Supracricoid laryngectomy: the impact of senescence on swallowing safety / Laringectomia supracricóidea: o impacto da senescência na segurança da deglutição

ABSTRACT: Objective: To investigate the association between aging and the functional aspects of swallowing (laryngeal penetration and laryngotracheal aspiration) in individuals who underwent supracricoid laryngectomy in the late period and without complaints. Methods: A total of 70 patients, 56 (80%) aged >60 years and 14 (20%) <60 years, under outpatient follow-up, after cancer treatment and with no complaints of swallowing, performed functional evaluation using the swallowing videofluoroscopy. Image classification was performed using the penetration-aspiration scale developed by Rosenbek. The χ2 test and logistic regression were applied to associate the age categories to the outcomes (penetration and aspiration). Results: Patients aged over 60 years had a higher prevalence of penetration (24.29%) and aspiration (48.57%) than patients aged under 60 years. In this sample, aspiration was associated with age. Patients aged over 60 years were more likely to present penetration (27% more) during swallowing than patients under 60 years. Patients aged over 60 years had an approximately four-fold greater probability of laryngotracheal aspiration than patients aged under 60 years. Conclusion: In patients without complaints of swallowing in the late postoperative period of supracricoid laryngectomy, there is a greater probability of laryngotracheal aspiration in elderly aged over 60 years than in individuals under 60 years.

RESUMO Objetivo: Investigar a associação entre o envelhecimento e os aspectos funcionais da deglutição (penetração laríngea e aspiração laringotraqueal) em indivíduos submetidos à laringectomia supracricóidea no período tardio e sem queixas. Métodos: Setenta pacientes, sendo 56 (80%) >60 anos e 14 (20%) <60 anos, em acompanhamento ambulatorial, após tratamento oncológico e sem queixas de deglutição, realizaram avaliação funcional por meio da videofluoroscopia da deglutição. A classificação das imagens foi realizada por meio da escala de penetração-aspiração desenvolvida por Rosenbek. O teste do χ2 e a regressão logística foram aplicados para associação das categorias de idade aos desfechos (penetração e aspiração). Resultados: Os pacientes com idade acima de 60 anos apresentaram maior prevalência de penetração (24,29%) e aspiração (48,57%) do que aqueles com idade inferior a 60 anos. Nesta amostra, a aspiração se mostrou associada à idade. Pacientes acima de 60 anos tiveram chance 27% maior de penetração durante a deglutição do que os com menos de 60 anos. Pacientes acima de 60 anos tiveram chance aproximadamente quatro vezes maior de aspiração laringotraqueal do que pacientes com menos de 60 anos. Conclusão: Em pacientes sem queixas de deglutição no pós-operatório tardio de laringectomia supracricóidea, há maior chance de aspiração laringotraqueal em idosos acima de 60 anos do que em indivíduos abaixo de 60 anos.

Supratracheal laryngectomy: a multi-institutional study / Laringectomia supratraqueal: um estudo multi-institucional

Abstract Introduction: Supratracheal laryngectomy has been described as a surgical procedure for glottic or supraglottic cancer extending to the subglottic region and/or involving the cricoarytenoid joint, aiming to preserve laryngeal function (breathing, phonation and swallowing), without diminishing locoregional cancer control. The choice of supracricoid laryngectomy in these cases could result in a high risk of compromised resection margins. Objective: To determine the safety, viability, adequacy of surgical margins and the supratracheal laryngectomy results for intermediate and advanced laryngeal cancer by reviewing the results at three different institutions in Brazil. Methods: This is a retrospective study that analyzed the charts of 29 patients submitted to supratracheal laryngectomy from October 1997 to June 2017. The type of laryngectomy performed was classified according to the European Laryngological Society classification for horizontal laryngectomies. Early and late results were evaluated. Survival rates (overall, specific, disease-free and total laryngectomy-free survival) were calculated. The mean follow-up time was 44 months. Results: Of the 29 patients submitted to supratracheal laryngectomy, 25 had no previous treatment. One patient (3.4%) had compromised margins. Four patients (13.8%) had recurrence. Of these, three had local recurrence and one had regional recurrence. Five patients (17.2%) required a total laryngectomy, two due to ruptured pexy and three due to local recurrence. Four of these patients (80%) achieved a successful total procedure. Four patients (13.8%) died, two due to postoperative complications and two due to recurrence. Overall, specific, disease-free and total laryngectomy-free survival at 5 years were, respectively, 82.1%; 88.2%; 83.0% and 80.2%. Conclusion: Selected patients with intermediate and advanced laryngeal cancer may benefit from supratracheal laryngectomy, that resulted in total laryngectomy-free survival and specific survival of 80.2% and 88.2%, respectively.

Resumo Introdução: A laringectomia supratraqueal tem sido descrita como um procedimento cirúrgico com objetivo de preservar a função da laringe (respiração, fonação e deglutição), sem prejuízo no controle oncológico locorregional, para câncer glótico ou supraglótico com extensão à subglote e/ou envolvimento da articulação cricoaritenóidea. A opção pela laringectomia supracricoide nesses casos poderia resultar em grande risco para margens de ressecção comprometidas. Objetivo: Determinar a segurança, viabilidade, adequação das margens cirúrgicas e os resultados da laringectomia supratraqueal para o câncer de laringe intermediário e avançado através da revisão dos resultados de três instituições distintas no Brasil. Método: Estudo retrospectivo, com análise dos prontuários de 29 pacientes submetidos à laringectomia supratraqueal, de outubro de 1997 a junho de 2017. O tipo de laringectomia realizada foi classificado de acordo com a classificação da Sociedade Laringológica Europeia para laringectomias horizontais. Foram avaliados os resultados precoces e tardios. As taxas de sobrevida (global, específica, livre de doença e livre de laringectomia total) foram calculadas. O tempo médio de seguimento foi 44 meses. Resultados: Dos 29 pacientes submetidos à laringectomia supratraqueal, 25 não tinham tratamento prévio. Um paciente (3,4%) teve margens comprometidas. Quatro pacientes (13,8%) recidivaram. Desses, três tiveram recidiva local e um apresentou recidiva regional. Cinco pacientes (17,2%) necessitaram de totalização da laringectomia, duas por ruptura da pexia e três por recidiva local. Quatro desses pacientes (80%) obtiveram sucesso na totalização. Quatro pacientes (13,8%) foram a óbito, dois por complicações pós-cirúrgicas e dois por recidiva. As sobrevidas global, específica, livre de doença e livre de laringectomia total em 5 anos foram, respectivamente, 82,1%; 88,2%; 83,0% e 80,2%. Conclusão: Pacientes selecionados com câncer intermediário e avançado de laringe podem ser beneficiados com laringectomia supratraqueal, que ofereceu sobrevida livre de laringectomia total e sobrevida específica de 80,2% e 88,2%, respectivamente.

Abstract Introduction Stomal recurrence is a troublesome complication after total laryngectomy. Despite a large number of studies having been performed, there is still controversy about which risk factors are most significant for the development of stomal recurrence. Objective The objective of the present meta-analysis was to analyze the potential factors leading to stomal recurrence after total laryngectomy. Methods PubMed, Web of Science, Cochrane Library, and Ovid databases were systematically searched using multiple search terms. Eighteen studies with 6462 patients were identified. The quality of evidence was assessed by The National Institute for Health and Clinical Excellence. Results The results showed that, tumor subsite (supraglottic vs. subglottic, RR = 0.292, 95% CI 0.142-0.600, p = 0.001; glottic vs. subglottic, RR = 0.344, 95% CI 0.175-0.676, p = 0.002), T stage (RR = 0.461, 95% CI 0.286-0.742, p = 0.001), preoperative tracheotomy (RR = 1.959, 95% CI 1.500-2.558, p < 0.001) were the high-risk factors associated with the development of stomal recurrence. Conclusion From the results of our study, tumor subsite, T stage and preoperative tracheotomy were the significant risk factors for stomal recurrence. Methodologically high-quality comparative investigations are needed for further evaluation.

Apesar de um grande número de estudos ter sido feito, ainda há controvérsias sobre quais fatores de risco são mais significativos para o seu desenvolvimento. Objetivo O objetivo da presente meta-análise foi analisar os fatores potenciais para recorrência estomal após a laringectomia total. Método As bases de dados PubMed, Web of Science, Cochrane Library e Ovid foram sistematicamente pesquisadas com vários termos de busca. Dezoito estudos com 6.462 pacientes foram identificados. A qualidade da evidência foi avaliada pelo National Institute for Health and Clinical Excellence. Resultados Os resultados mostraram que o subsítio tumoral (supraglótico vs. subglótico, RR = 0,292, IC 95% 0,142 ± 0,600, p = 0,001; glótico vs. subglótico, RR = 0,344, IC 95% 0,175 ± 0,676, p = 0,002), estágio T (RR = 0,461, IC 95% 0,286 ± 0,742, p = 0,001), traqueotomia pré-operatória (RR = 1,959, IC 95% 1.500 ± 2.558, p < 0,001) foram os fatores de alto risco associados ao desenvolvimento de recorrência estomal. Conclusão Com base nos resultados de nosso estudo, o subsítio do tumor, o estágio T e a traqueotomia pré-operatória foram fatores de risco significativos para recorrência estomal. São necessárias investigações comparativas metodologicamente de alta qualidade para maior avaliação.

Outcome of multidisciplinary treatment in laryngeal cancer. Retrospective study with 10-years follow-up.

BACKGROUND: In laryngeal cancer, multidisciplinary treatment improves the patient's quality of life and the possibility of preserving the larynx. Most cases occur in a locally advanced stage. The aim is to present the results according to the stage. METHOD: A retrospective study which analyzed the clinical stage, type of primary treatment, outcomes, and survival were analyzed. RESULTS: 451 patients were included. The median age was 66 years. The majority of the tumors presented in advanced stage (72%) and the most affected subsite was the glottis (84.5%). In the early stage the most frequent treatment was radiotherapy as the only treatment modality. In stages III and IVA, 65% were resectable. In stage IVB the management was non-surgical, with control in 26% of the cases. Survival at 10 years was related to the clinical stage: 81.7% for stage I and 0% for stages IVB and IVC. CONCLUSIONS: Patients with laryngeal cancer should be treated according to the clinical stage, through a multidisciplinary approach. Long-term follow-up showed a worse prognosis for advanced clinical stages.
