Intratympanic and Round-Window Drug Therapy: Effect on Cochlear Tinnitus.

Author information

  • 1Midwest Ear Institute, Indianapolis, IN.


Tinnitus is a common symptom for which few existing therapeutic approaches can produce reliable reduction or elimination. Chemical perfusion involves the delivery of medication directly into the inner ear via the round-window membrane. This report discusses the use of dexamethasone or gentamicin in 20 individuals who had inner ear diseases in which disturbing cochlear tinnitus was one of the symptoms. Preliminary results indicate that chemical perfusion is a promising option for the treatment of cochlear tinnitus.
