Baclofen in hemifacial spasm.

A 58-year-old woman with long-standing hemifacial spasm experienced dramatic relief of symptomatology while receiving baclofen (Lioresal) in a daily dosage of 37.5 mg. Clinical response was noted within 48 h and she remained asymptomatic during 12 months of treatment. No toxic or side-effects were observed. Controlled studies are needed to establish the role of baclofen in hemifacial spasm.
