Our previous reports dealt with tinnitus and impaired hearing as autonomic dysfunction in the field of otorhinolaryngology. In 46 patients, tinnitus without hearing loss or with impaired hearing of low-pitched sounds was the manifestation of autonomic dysfunction, as diagnosed by Schellong's test and T. M. I. These patients were treated orally with Tofisopam 150mg daily (50mg three times a day), and changes in the severity of tinnitus were monitored. The treatment was markedly effective or somewhat effective in 32 (70%) of the 46 patients. Schellong's test done at intervals of 2 weeks became negative in 70% of the 20 patients. These results indicate that Tofisopam is effective in the treatment of tinnitus.
