Background: Idiopathic sudden sensorineural hearing loss(ISSHL) has been generally defined as an abrupt loss of auditory acuity without precipitating factors. Since ISSHL was first described as a disease entity, numerous reports assessing a variety of treatment regimens have been published. But its etiology, pathogenesis, treatment, and prognosis are controversial at the present time. Stellate ganglion block(SGB) has been used for the treatment of ISSHL by vasodilatation and increased blood flow to the inner ear. Methods: We reviewed the records of 152 patients to investigate the efficacy of SGB for ISSHL. The control group was managed with medications such as hypaque, heparin, steroid, nicotinic acid, and vitamins. The SGB group was managed with SGB and the same medications. SGB was performed with 8 ml of 1.0% mepivacaine. The efficacy of treatment was evaluated by pure-tone average following therapy. The recovery of hearing was defined as Siegel's criteria I, II, or III. Results: The recovery rate of the SGB group was higher than that of the control group(61.5 vs. 42.9%, p<0.05). The recovery rate was higher in patients who were treated early, within 7 days from the onset of symptoms, especially in the SGB group(79.7%). And in the case that initial hearing loss was severe (>70dB), the SGB group had a higher recovery rate(64.2%) than the control group(42.5%). Conclusions: SGB is thought to be a useful therapy for ISSHL, especially in the patients who were treated soon after onset or whose initial hearing loss was severe.
