A case of cerebellopontine angle meningioma with restoration of hearing from a profoundly deaf state is presented. Meningiomas of the posterior fossa commonly present with decreased or absent hearing and can appear deceptively similar to acoustic neurinomas on radiographic and audiometric testing. Because total restoration of hearing can occur with meningioma, even with significant preoperative deficit, utilization of the translabyrinthine approach is less desirable if any preoperative question as to the diagnosis exists. Any hearing-impaired patient with a cerebellopontine angle mass that is not conclusively thought to represent acoustic neurinoma should be approached by the suboccipital technique to maximize the opportunity for restoration of hearing.
本文报告1例桥小脑角脑膜瘤患者，其听力从极重度聋状态恢复。后颅窝脑膜瘤通常表现为听力减退或丧失，在影像学和听力测试中可能看似与听神经瘤极为相似。由于脑膜瘤即便术前听力严重受损也可能实现听力完全恢复，因此，若术前对诊断存在任何疑问，采用经迷路入路就不太可取。对于任何患有桥小脑角肿物且不能明确诊断为听神经瘤的听力受损患者，应采用枕下技术，以最大程度增加听力恢复的机会。
