Abstract

Hemifacial spasm is a distressing condition characterized by involuntary, intermittent, unilateral twitching of all or parts of the muscles innervated by the facial nerve. This occurrence is most common in middleaged women. Because etiology of idiopathic hemifacial spasm has remained undefined, no causative agent nor reliable treatment has been established. This report describes a case of CT guided chemical facial nerve block for the treatment of hemifacial spasm. An injection of small amount (0.1 ml) of alcohol (95%) provided relief of the facial spasms.
