GOAL
The aim of this study was to assess hearing improvement after myringoplasty.
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.
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.
CONCLUSIONS
Myringoplasty is an effective technique in the recovery of hearing thresholds secondary to a tympanic membrane perforation.
目的
本研究旨在评估鼓膜成形术后听力的改善情况。
材料与方法
我们进行了一项回顾性研究，对我院接受鼓膜成形术的119例患者进行分析，比较手术前及术后6个月的气导阈值。我们对不同变量进行方差分析，并使用学生t检验对假设进行对比。
结果
除8000Hz外，所有频率的听力均有改善，而在该频率手术明显导致听力恶化。频率越低，听力改善越明显，在250Hz时效果最佳，平均听力改善达13.49dB。
结论
鼓膜成形术是恢复鼓膜穿孔继发听力阈值的有效技术。
