Abstract: Goal: The aim of this study was to assess hearing improvement after myringoplasty.<br />Material and Methods: We present a retrospective study with a total of 119 cases undergoing myringoplasty at our Department analyzing 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.<br />Results: We obtained a hearing improvement at all frequencies, except at 8.000 Hz, at which surgery noticeably worsens hearing. The lower the frequency, the higher the hearing improvement, with the best results at 250 Hz, where the mean hearing improvement reached 13.49 dB.<br />Conclusions: Myringoplasty is an effective technique in the recovery of hearing thresholds secondary to a tympanic membrane perforation.<br /> (Copyright 2009 Elsevier España, S.L.
