Clasificación de las resecciones transorales en la orofaringe: propuesta del grupo de trabajo de la Sociedad Catalana de Otorrinolaringología / Transoral oropharyngeal resection classification: Proposal of the SCORL working group

Introducción y objetivos: La cirugía mínimamente invasiva ha presentado una expansión muy importante en la última década. Con el objetivo de aportar un lenguaje común tras cirugía transoral de la orofaringe, se ha creado un sistema de clasificación de las resecciones en esta zona, independientemente de la instrumentalización utilizada. Métodos: Desde el Grupo de Trabajo en Oncología de la Sociedad Catalana de Otorrinolaringología, se presenta una propuesta de clasificación basada en una división topográfica de las diferentes zonas de la orofaringe, así como en la afectación de las estructuras anexas según las vías anatómicas de extensión de estos tumores. Resultados: La clasificación se inicia utilizando la letra D o I según la lateralidad sea derecha (D) o izquierda (I). A continuación se coloca el número del área resecada. Esta numeración define las zonas iniciando a nivel craneal donde el área I sería el paladar blando, el área II lateral en la zona amigdalina, el área III en la base de lengua, el área IV en los repliegues glosoepiglóticos, la epiglotis y repliegues faringoepiglóticos, el área V pared orofaríngea posterior y VI el trígono retromolar. Se añade el sufijo p si la resección afecta profundamente al plano submucoso de la zona comprometida. Las diferentes áreas propuestas tendrían, de una forma teórica, diferentes implicaciones funcionales. Conclusiones: Propuesta de sistema de clasificación por áreas que permite definir diferentes tipos de cirugía transoral de la orofaringe así como compartir los resultados y ayudar en la docencia de este tipo de técnicas (AU)

Introduction and goals: There has been a very significant increase in the use of minimally invasive surgery has in the last decade. In order to provide a common language after transoral surgery of the oropharynx, a system for classifying resections has been created in this area, regardless of the instrumentation used. Methods: From the Oncology Working Group of the Catalan Society of Otorhinolaryngology, a proposal for classification based on a topographical division of the different areas of the oropharynx is presented, as also based on the invasion of the related structures according to the anatomical routes of extension of these tumours. Results: The classification starts using the letter D or I according to laterality either right (D) or left (I). The number of the resected area is then placed. This numbering defines the zones beginning at the cranial level where area I would be the soft palate, lateral area II in the tonsillar area, area III in the tongue base, area IV in the glossoepiglottic folds, epiglottis and pharyngoepiglottic folds, area V posterior oropharyngeal wall and VI the retromolar trigone. The suffix p is added if the resection deeply affects the submucosal plane of the compromised area. The different proposed areas would, in theory, have different functional implications. Conclusions: Proposal for a system of classification by area to define different types of transoral surgery of the oropharynx, and enable as sharing of results and helps in teaching this type of technique (AU)

[Myringoplasty: auditory follow-up and study of prognostic factors]. / Miringoplastia: seguimiento auditivo y estudio de factores pronósticos.

OBJECTIVE: To perform a five-year study of hearing evolution in patients undergoing myringoplasty to determine whether eardrum repair correlates with improved hearing. We also studied factors that might predispose to failure and their usefulness as prognostic factors. MATERIAL AND METHOD: In a serial case study, we reviewed all myringoplasties performed at our centre during 2000, 2001, and 2002. We reviewed 83 case histories and studied the closure of the perforation, auditory function pre-operatively, postoperatively and after 5 years, as well as different associated factors. RESULTS: The perforation was closed in 75.9 % of cases. The mean gain of auditory function was 1.5 dB at five years, without statistical significance. The hearing evolution presented a post-surgical improvement and a subsequent deterioration, both statistically significant. We found a statistically significant relationship between the size of the perforation and the condition of the contralateral ear. CONCLUSIONS: Perforation closure in our series (75.9 %) is similar to that reported in the literature. We found contralateral ear pathology and the perforation extension to be associated with poor prognosis after myringoplasty.

Miringoplastia: seguimiento auditivo y estudio de factores pronósticos / Myringoplasty: auditory follow-up and study of prognostic factors

Objetivo: Realizar un estudio a 5 años de la audición de los pacientes sometidos a miringoplastia a fin de probar si la restitución timpánica tiene correlación con la mejora auditiva. Se investigan también posibles factores predisponentes al fracaso y averiguar si podemos describirlos como factores pronósticos. Material y método: Se realiza estudio tipo serie de casos y una revisión de las miringoplastias realizadas en nuestro centro en los años 2000, 2001 y 2002. Se revisaron 83 historias y se estudió el cierre de la perforación, la función auditiva prequirúrgica, posquirúrgica y a 5 años, así como diferentes factores relacionados. Resultados: Se obtiene un cierre de la perforación en el 75,9 % de los casos. En cuanto a la función auditiva, obtenemos una ganancia sin significación estadística de 1,5 dB a los 5 años. La evolución auditiva presenta una mejora posquirúrgica y un empeoramiento posterior, ambos estadísticamente significativos. Se ha obtenido una relación estadística en el tamaño de la perforación y el estado del oído contralateral. Conclusiones: Se presenta un resultado de cierre de la perforación acorde con la mayoría de las series. El estado patológico del oído contralateral y la extensión de la perforación son factores de mal pronóstico de la miringoplastia (AU)

[Stapedotomy outcomes in the treatment of otosclerosis: our experience]. / Resultados de la estapedotomía en el tratamiento de la otosclerosis: nuestra experiencia.

OBJECTIVE: The main objective of our study is to identify whether there is measurable audiometric deterioration in patients undergoing stapedotomy with a follow-up of more than eight years. MATERIAL AND METHOD: We conducted a retrospective clinical study in which we reviewed a total of 150 case histories of patients with stapedotomy at our department between 1993 and 1997, with a successful initial audiological assessment using tone audiometry in the first three months after surgery and later audiometrical follow-up. RESULTS: We obtained a significant mean post-operative hearing impairment of 1.02 dB per year, with a pre-operative mean PTA of 51.45 dB, going on to early post-operative mean PTA of 26.71 dB, and later post-operative mean PTA of 35.42 dB, with all these changes turning out to be statistically significant. CONCLUSIONS: The auditory level obtained after surgery worsens as the years go by, but always without exceeding the hearing loss prior to surgery.

Objetivo: Nos propusimos valorar el deterioro audiométrico de los pacientes intervenidos de estapedotomía, con un seguimiento mayor de 8 años. Material y método: Realizamos un estudio clínico retrospectivo en el que revisamos un total de 150 historias de pacientes intervenidos de estapedotomía entre los años 1993 y 1997 en nuestro servicio, con buen resultado audiológico inicial valorado mediante audiometría tonal en los primeros 3 meses tras la cirugía y con seguimiento audiométrico posterior. Resultados: Obtuvimos una media de deterioro auditivo postoperatorio significativa (1,02 dB por año), con una media auditiva preoperatoria de 51,45 dB, que pasa a una media de 26,71 dB en el postoperatorio temprano, y una media de 35,42 dB en el postoperatorio tardío; todos estos cambios son estadísticamente significativos. Conclusiones: El nivel auditivo obtenido tras la cirugía empeora con el paso de los años; pero siempre sin sobrepasar la pérdida auditiva previa a la cirugía (AU)

[Abnormal internal carotid artery in the middle ear and severe otorrhagia after myringotomy]. / Arteria carótida aberrante. A propósito de un caso.

We present a clinical-surgical case of a 72-year-old woman referred from another Hospital due to presentation of otorrhagia following myringotomy. We later determined by means of imaging studies that it was a case of an aberrant internal carotid artery. All masses in the middle ear, especially pulsing masses, must be studied by imaging methods such as computerized tomography and, preferably, magnetic resonance angiography.
