Abstract

Clinical effects of metyl B₁₂ were evaluated in 30 patients with tinnitus at the ENT clinic of Okayama University Hospital. All patients suffered from subjective tinnitus. In 27 cases the tinnitus was accompanied by sensorineural hearing loss, 3 cases were without hearing loss. Methyl B12 was administrated 1,500 μg/day for 8 weeks to all patients. The patients were tested by “standard tinnitus test 1984” and pure tone audiometry, before and after 8 weeks admdinistration. 18 of 30 cases were improved. General efficacy rate was 60%. No side effects were noted in any case.
