We report two unusual cases of delayed hearing loss after microvascular decompression (MVD) for hemifacial spasm. In the first case, A 59-year-old female noted left hearing loss one week after receiving MVD for left hemifacial spasm. In the second case, A 39-year-old male also noticed ipsilateral hearing loss on the 7th day after MVD for right hemifacial spasm. Both cases were treated by steroid. Two months after the onset, their hearing function improved dramatically. These cases indicated that the delayed hearing loss after MVD for hemifacial spasm can occur, even when gentle microsurgical technique is used, but the prognosis for this condition is fairly good.
我们报告了两例微血管减压术（MVD）治疗面肌痉挛后出现迟发性听力损失的罕见病例。第一例中，一名59岁女性在接受左侧面肌痉挛微血管减压术后一周出现左耳听力损失。第二例中，一名39岁男性在接受右侧面肌痉挛微血管减压术后第7天也出现同侧听力损失。两例均采用类固醇治疗。发病两个月后，他们的听力功能显著改善。这些病例表明，即使采用轻柔的显微外科技术，面肌痉挛微血管减压术后仍可能发生迟发性听力损失，但这种情况的预后相当良好。
