Abstract
-
Hemimasticatory spasm is a rare disorder that often accompanies facial hemiatrophy and is characterized by spasm in one or more of the jaw-closing muslces supplied by the fifth cranial nerve. We report a clinical and electrophysiological observation of a patient of hemimasticatory spasm, who presented involuntary spasm on masseter muscle and hemiatrophy of the face on the right side for 7 years.
