Frequency-specific hearing studies are important for predicting hearing results and the prognosis after stapes surgery, to prepare for the rehabilitation of frequency-specific hearing in patients with otosclerosis. To evaluate outcomes of stapes surgery of Chinese otosclerosis patients with different degrees of hearing loss. We conducted a retrospective analysis of 213 otosclerosis patients who underwent stapes surgery in our hospital. Pre- and post-operative audiometric evaluation using conventional audiometry. The post-op ABG was less than 20 dB in 94.52% of all cases after surgery. There was no statistical significance of the post-op ABG among different groups at all frequencies except extremely severe group ( < .05). There was a significant improvement of both AC and BC thresholds in post-op period and the most significant improvement was found in severe group. There were no serious post-op complications and no re-operations during the follow-up period. Stapes surgery is a suitable treatment option for otosclerosis with mild to extremely severe HL. The mild to moderate hearing loss groups had the most significant improvement of AC thresholds in the low frequency region, and the severe to extremely severe groups appeared in the high frequency region.
频率特异性听力研究对于预测听力结果和镫骨手术后的预后，以及为耳硬化症患者的频率特异性听力康复做准备非常重要。评估不同听力损失程度的中国耳硬化症患者镫骨手术的结果。我们对在我院接受镫骨手术的 213 例耳硬化症患者进行了回顾性分析。术前和术后均采用常规听力评估进行听力学评估。术后所有病例的 ABG 均小于 20 dB，除极重度组外（ < .05），各频率组间术后 ABG 无统计学意义。术后 AC 和 BC 阈值均有显著改善，重度组改善最明显。随访期间无严重术后并发症，无再次手术。镫骨手术是治疗轻至极重度 HL 耳硬化症的合适选择。轻至中度听力损失组低频区 AC 阈值改善最显著，重度至极重度组高频区改善最显著。
