Abstract

Hemifacial spasm (HFS) is characterized by painless unilateral involuntary contractions (spasm) of the mimic muscles innervated by the seventh cranial nerve. At the beginning of the disease, the contractions usually occur in the orbicularis oculi muscle and later on progress to involve the entire ipsilateral face over several years. Nevertheless, both bilateral occurrence [1] and familial incidence [2] are described in a few cases. HFS occurs with greater incidence on the left facial sice [3], with women being more affected than men (Ratio 2 : 1).
