title: [Early stellate ganglion block failed to prevent progress of facial nerve palsy in a patient with Ramsay-Hunt syndrome--a case report].
abstract: A 73-year-old man complained of pain in his right ear with vesicular lesion for three days. He complained of no weakness of facial musculatures, but muscle test revealed slight weakness in orbital and oral muscles on admission. His hearing acuity of the left ear was intact. Vertigo with spontaneous nystagmus to left was complained. The patient was treated with stellate ganglion block four times a day, prednisolone 80 mg a day p.o. and acyclovir i.v. Mannitol solution 300 ml a day for eight days was given i.v. to reduce edema and to protect facial nerve. On his 3rd hospital day, his paralysis progressed and he could not close his eye or whistle with his mouth. Evoked myogram showed 91% impairment of the nerve. During recovery period there was discrepancy between facial palsy score of clinical signs and degree of nerve impairment by evoked myogram. On his 12th hospital day his facial nerve score improved 9 to 12 (0 complete paralysis, 40 no paralysis) but evoked myogram showed further progress of nerve impairment from 86% to 91% (Evoked wave heights were 14% and 9% of normal site respectively). The discrepancy is probably because facial palsy score reflects also neurapraxia of inflammatory nerve, and stellate ganglion block has no effect on changing course of facial nerve injury.
