[Typewriter tinnitus treated with gabapentin].

Typewriter tinnitus (TT) is a rare subtype of tinnitus but different in many ways, and it is treatable in most cases with carbamazepine. TT is defined by characteristic staccato sounds like a typewriter, intermittent and chronic. Compression of the eigth cranial nerve by a vascular loop of the anterior inferior cerebellar artery is believed to be the cause of TT. Additional symptoms, paroxysmal vertigo and hemifacial spasms are often accompanying TT. This case report describes a 43-year-old woman with typical symptoms and findings, who had an excellent response to treatment with gabapentin.
