title: Hemifacial spasm: early postoperative normalization of blink reflex latency.
abstract: Electrophysiological improvement in the blink reflex latency after neurovascular decompression of the facial nerve in patients with hemifacial spasm is believed to be related to remyelination and occurs 2-8 months after surgery. We report a patient with hemifacial spasms for 3 years, in whom the increased blink reflex latency returned to normal within a week after surgery. This suggests that compression without demyelination may be responsible for increased blink reflex latency in some of the patients with hemifacial spasms.
