The outcome of tinnitus therapy, systemically performed in our clinic, was reviewed. Lidocain was intravenously injected into 247 patients who complained of tinnitus. Fifty two (21.0%) of them had complete relief from tinnitus,126 (51.0%) had partial relief (over 30% disappearance of tinnitus by subjective evaluation). Forty one patients were given sodium valproate (400 mg orally twice a day, Group 1), thirty eight patients were given mexiletine HC1 (300 mg orally three times a day, Group 2), and sixty nine patients were given eperisone HC1 and minor tranquilizer (each one tablet orally three times a day, Group 3). All patients in Group 1to 3 were given the drugs after being tested for the effects of intravenous lidocaine (40-60 mg). The results obtained for Group 3 were the most correlated with the effect of lidocaine. Twenty four ears were treated with transtympanic injection of dexamethason. In 12 ears, tinnitus was improved (30-80% subjective disappearance). Twenty four patients were treated with band noise ma s kers, and 10 of them (42%)had partial and complete relief from tinnitus. It was concluded that these different therapies should be used in combination to obtain better relief from tinnitus.
