Abstract
Objective

The aim of this study was to present myringoplasty case results in our department. Different factors were studied to confirm their prognostic value.

Materials and methods

A total of 126 myringoplasties from 2006 until 2010 were reviewed, collecting patient-related details, descriptions of the anatomical defect and the most interesting surgical aspects.

Results

Subtotal perforations (35.7%) were the most frequently observed. In 89.7% of the operations, the transcanal approach was preferred. The medial technique (underlay) to the tympanic membrane was the most performed (97.6%). Cartilage was the principal graft used (82.5%).

Complete closure of the perforation was obtained in 71.1% of the cases at 6 months follow-up. Recurrences of the perforations were of minimal size in 11.9% of the cases, partial in 11.1% and with a cartilage fragment gap in 4.8%. The mean time in which these defects were registered was 3.82 months.

The mean post-operative auditory gain was 12.8 decibels at 6 months.

Conclusions

Myringoplasty is an appropriate technique for restoring tympanic integrity and obtaining functional benefit.

Dried middle ear mucosa and posterior perforations seem to be related with better functional results.

Resumen
Objetivo

El objetivo de este trabajo es presentar, de forma detallada, nuestros resultados en la cirugía de la reconstrucción de la membrana timpánica y sobre todo los diferentes factores que influyen en los resultados con el fin de contrastar su valor pronóstico.

Métodos

Hemos revisado un total de 126 miringoplastias desde 2006 hasta 2010, recopilando los datos del paciente, la descripción del defecto anatómico y los aspectos más relevantes de la propia intervención.

Resultados

Las perforaciones subtotales (35,7%) fueron las más frecuentes. En el 89,7% se realizó el abordaje transcanal. La técnica medial (underlay) fue la más empleada (97,6%). Como injerto se utilizó principalmente el cartílago (82,5%).

Se consiguió un cierre completo de la perforación en el 71,1% a los 6 meses de seguimiento. Las reperforaciones fueron de tipo puntiforme en el 11,9%, parcial en el 11,1% y dehiscencia de los fragmentos de cartílago en el 4,8%. El tiempo medio en el cual se registró el defecto de la cirugía fue a los 3,82 meses.

La ganancia auditiva media fue de 12,8 dB a los 6 meses de la intervención.

Conclusiones

La miringoplastia constituye una técnica adecuada para la restitución de la integridad timpánica y para la obtención de un beneficio funcional.

Un estado de la caja seco y las perforaciones posteriores parecen relacionarse con un mejor pronóstico funcional.
