  • Abstract
  • Look Inside

A 47-year-old man complained of tinnitus in his left ear for 4 years. One year ago he started to complain of abnormal sensation of hearing. He presented with a hearing loss and weakness of facial movement on his left side, no caloric response, but no equilibrium disorder. CT scan revealed a masslesion with marginal high density area in the left internal anditory meatus and middle cranial fossa.

Intraoperative finding showed that a schwan-noma which originated from the facial nerve in the internal auditory meatus and extended to the mid-dle cranial fossa with a destruction of upper roof of the internal auditory meatus. No fistula to the inner ear was found.

We considered that the destruction of upper roof of the internal auditory meatus and the facial canal relieved a pressure on the facial nerve in the internal auditory meatus by the tumor.
