Abstract
Objective

The aim of this study was to assess hearing improvement after myringoplasty.

Materials and method

We present a retrospective study with a total of 119 cases undergoing myringoplasty at our Department analysing the air conduction thresholds before and 6 months after surgery. We conducted an analysis of variance for the different variables and contrasted hypotheses using Student's t-test.

Results

We obtained a hearing improvement at all frequencies, except at 8,000Hz, at which surgery noticeably worsened hearing. The lower the frequency, the higher the hearing improvement was, with the best results at 250Hz, where the mean hearing improvement reached 13.49 dB.

Conclusions

Myringoplasty is an effective technique for recovering hearing thresholds secondary to a tympanic membrane perforation.

Resumen
Objetivo

Determinar la mejoría de los umbrales auditivos tras la realización de una miringoplastia.

Materiales y método

Utilizamos un estudio restrospectivo con un total de 119 casos intervenidos de miringoplastia en nuestro servicio analizando los umbrales aéreos pre- y posquirúrgicos a los 6 meses de la intervención. Se realiza un análisis de varianzas para las distintas variables y un contraste de hipótesis utilizando una T-Student.

Resultados

Se obtuvo una mejoría en umbrales aéreos en todas las frecuencias, excepto en 8.000Hz, en los que la cirugía empeora la audición sensiblemente. La ganancia auditiva es mayor cuanto más baja es la frecuencia, con lo que se obtuvo el resultado máximo en 250Hz, donde la mejoría auditiva media llegó hasta los 13,49 dB.

Conclusiones

La miringoplastia es una técnica eficaz en la recuperación de umbrales auditivos secundarios a un defecto de la membrana timpánica
