Botox transient treatment of tinnitus due to stapedius myoclonus: case report.

OBJECT: To explore the feasibility of using botulinum toxin type A (BTXA) to treat tinnitus due to stapedius myoclonus. METHOD: A piece of gelfoam containing BTXA (25 U/ml) was placed, through a perforation in tympanic membrane, into the middle ear cavity of a patient suffering from tinnitus due to stapedius myoclonus. RESULTS: The tinnitus disappeared on the second day after the BTXA treatment. The patient was free of symptoms during a 3-month follow-up period. Tinnitus reappeared at 4 months, and disappeared after second BTXA local treatment. CONCLUSION: Local BTXA treatment may be considered as a treatment for tinnitus caused by stapedius myoclonus.
