Abstract
Introduction

Multiple surgical techniques have been proposed to close tympanic perforations. Eavey, two decades ago, described a technique aimed at closing central perforations in children. For this, he designed a butterfly-shaped cartilage graft that was placed between the tympanic membrane in an inlay manner. This technique showed great effectiveness for the closure of perforations as well as low morbidity, rapidity and great economic difference.

Methods

We performed a descriptive study of a series of cases analysing 32 interventions in children and adults with the modified Eavey technique, during the period from January 2012 to November 2016. We evaluated the surgical and audiometric functional results.

Results

Surgical success was achieved in 93% of cases, including complete closures in 27 patients (84%) and 3 cases in which minimal asymptomatic dehiscences occurred. There was rejection of the graft and persistence of the perforation in only one case. No major surgical or postoperative complications associated with the procedure were described. The mean improvement in the audiometric gap was from 17dB preoperatively to 7dB after the intervention.

Conclusions

The modified Eavey technique is a low morbidity, cost-effective procedure with a technical facility that proves effective for the closure of tympanic perforations in adults and children.

Resumen
Introducción

Se han propuesto múltiples técnicas quirúrgicas para cerrar perforaciones timpánicas. Eavey, hace dos décadas, describió una técnica destinada a cerrar perforaciones centrales en niños. Para ello diseñó un injerto de cartílago con forma de alas de mariposa que se colocaba entre la membrana timpánica. Dicha técnica demostró gran efectividad para el cierre de perforaciones así como baja morbilidad, rapidez y gran diferencia económica.

Métodos

Se realiza un estudio descriptivo de serie de casos analizando 32 intervenciones en niños y adultos con la técnica de Eavey modificada, durante el periodo de enero de 2012 a noviembre de 2016. Se evaluaron los resultados quirúrgicos y los resultados funcionales audiométricos.

Resultados

El éxito quirúrgico se logró en el 93% de los casos, incluyendo los cierres completos en 27 pacientes (84%) y 3 casos en los que se presentaron dehiscencias mínimas asintomáticas. Se presentó un rechazo del injerto y persistencia de la perforación y en un caso una perforación residual. No se describen complicaciones quirúrgicas o posquirúrgicas mayores asociadas al procedimiento. La mejoría de la media del gap audiométrico fue de 17dB preoperatorio a 7dB posterior a la intervención.

Conclusiones

La técnica de Eavey modificada es un procedimiento con baja morbilidad, costo-efectiva, con facilidad técnica que demuestra ser eficaz para el cierre de perforaciones timpánicas en adultos y niños.
