Effects of Stellate Ganglion Blocks for Sudden Deafness / 대한마취과학회지

ABSTRACT

Forty-four patients with sudden sensorineural hearing loss were treated with stellate ganglion block. The results were as follows. The results showed highest incidence in the decade between 30 and 50 years. The incidence of unilateral involvement were 40 cases (90.9%), among them 26 cases (59.1%) were right side. Among 44 patients 8 (18.2%) showed complete recovery, 9 (20.5%) partial recovery and 16 cases (36.4%) slight improvement by pure tone gain. These results showed a relative superiority of stellate ganglion block to other therapeutic regimens such as vasodilators, corticosteroids, anticoagulants etc. The time interval from onset of symptoms to start of stellate ganglion block seems to be important. Prognosis was slight poor in cases of sudden hearing loss with vertigo.
