Abstract
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.
