Abstract

A 53-year-old male presented with hearing impairment and facial nerve paralysis following tinnitus of the right ear. Neuroimaging revealed a tumor extensively damaging the temporal bone, and extending into the middle cranial fossa and cerebellopontine angle. The tumor was removed in a two-stage operation. The histological diagnosis was facial schwannoma.
