Tinnitus is an otological symptom which is often encountered but yet difficult to treat. If tinnitus is of cochlear origin then it seems reasonable to assume that a total depression of the cochlear function will abolish cochlear tinnitus. To achieve this depression, transtympanic injections of dexamesasone were conducted in patients suffering from tinnitus.
One hundred and nine patients (138ears) with tinnitus were included in this study.
Dexamesasone was applied to the middle ear cavity by transtympanic injections.
Our results are summarized as follows:
1) In 87 ears, tinnitus was abolished
2) In 39 ears, tinnitus was considerably ameliorated
3) In 14 ears, tinnitus was slightly ameliorated or no effect.
