Excerpt

Hemifacial spasm (HFS) has an overall prevalence of ∼7 to 15 in 100,000 individuals, affecting females twice as commonly as males, with age at diagnosis in the 5th and 6th decades.1 The condition manifests as involuntary, tonic, or clonic contractions of muscles involving 1 side of the face.2,3 In typical HFS, the orbicularis oculi is affected initially, with caudally progressing muscular involvement, including orbicularis oris, buccinators, and platysma.4 HFS is largely a unilateral condition, though rare cases of bilateral symptoms have been reported. HFS may cause significant social distress consequent to unpredictable facial twitching, leading to depression, poor social interactions, and difficulties with vision, which results in an overall decreased quality of life.
