Abstract
Objective

To perform a 5-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, post-operatively 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 5 years, without statistical significance. The hearing evolution presented a postsurgical 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.

Resumen
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.
