Abstract

This important multicenter study of 103 tinnitus out-patients during a 13-month treatment period was carried out by ten E.N.T. specialists, using the double blind, drug versus placebo method. The results were conclusive as regards the effectiveness of Ginkgo biloba extract and made it possible to determine the prognostic value of different parameters. Of special importance among these parameters were site and periodicity of the disease. However, the Ginkgo biloba extract treatment improved the condition of all the tinnitus patients, irrespective of the prognostic factor.
