The purpose of this study was to determine whether revision stapedectomy could precipitate sensorineural hearing loss in the contralateral ear.
We conducted a retrospective review of 148 patients undergoing primary or revision stapedectomy at an academic, tertiary care facility.
Stapedectomy resulted in significant improvements in mean air conduction thresholds in the ipsilateral ear. Overall, there were no significant changes in either the air or bone conduction values of the contralateral ear. Two patients demonstrated a >20-dB decline in speech reception threshold and/or >20% decrease word recognition in the contralateral ear. Both of these patients demonstrated the decline only after revision surgery.
Revision stapedectomy is on rare occasions associated with hearing loss in the contralateral ear. Contralateral hearing loss after revision stapedectomy may be due to sympathetic cochleolabyrinthitis.
本研究旨在确定翻修镫骨切除术是否会导致对侧耳感音神经性听力损失。
我们对一家学术性三级护理机构中148例行初次或翻修镫骨切除术的患者进行了回顾性研究。
镫骨切除术使同侧耳平均气导阈值有显著改善。总体而言，对侧耳的气导或骨导值均无显著变化。两名患者对侧耳言语接受阈值下降>20 dB和/或单词识别率下降>20%。这两名患者均仅在翻修手术后出现听力下降。
翻修镫骨切除术极少会导致对侧耳听力损失。翻修镫骨切除术后对侧听力损失可能是由于交感神经性耳蜗迷路炎。
