Hemifacial Spasm

Hemifacial spasm implies intermittent or persistent abnormal contraction of one half of the face due to conflict between an abnormally placed artery and the facial nerve (nerve that moves muscles of one half of the face). While botos injections can give short-term relief, the effect lasts about three months. Surgery (microvascular decompression) gives permanent cure and freedom from spasms as well as from requirement of repeated botox injections. Surgery involves separation of the offending artery from the facial nerve and is performed by a small (‘keyhole’) incision behind the ear. Long-term results are excellent.
