Is Hemifacial Spasm a Phenomenon of the Central Nervous System? – The Role of Desflurane on the Lateral Spread Response

Hemi-facial spasm (HFS) is a unilateral, involuntary and irregular twitching of the facial muscles. HFS can be managed clinically using serial botulium toxin (Botox) injections into the affected muscles or surgically treated with microvascular decompression (MVD) of the facial nerve. The etiology of HFS was originally suggested by Gardner (1962) and subsequently refined to include vascular (arterial or venous) compression of the facial nerve at the root entry/exit zone (Janetta et al., 1977; Moller and Jannetta, 1985, 1986, 1987).
