To evaluate the the efficacy and feasibility of electrical promontory stimulation in treating severe disabling tinnitus.Treated 12 cases of severe disabling tinnitus with EPS, and evaluated the alterations of tinnitus severity scale before and after the treatment.The effect on tinnitus was assessed during and immediately after the stimulation by tinnitus severity scores. Immediately after EPS, 5 patients reported complete suppression,the duration of persistence time were 10 s-20 h, and 5 reported attenuation of tinnitus, the lasting time were 2-24 h. 2 patients said it was unchanged. After 3 days, the tinnitus severity scores remained unchanged in all these patients.In our opinion EPS could be a effective method for suppressing and alleviating tinnitus , but poor results in patients with longterm effects and compliance. It is not suggested that EPS could be a routine method of treatment for tinnitus.
