A Case of Palatal Myoclonus Tinnitus Treated with Botolinum Toxin Injection / 대한이비인후과학회지

ABSTRACT

Palatal myoclonus, a kind of objective tinntius, is an uncommon disorder which shows rhythmic involuntary movement of the muscles of soft palate. Because of inadequate response of the muscles involved in palatal myoclonus to medical therapy, injection of botulinum toxin has been considered. We report a case of palatal myoclonus which had not responded to medical therapy. Injection of botulinum toxin into the muscle under the electromyographic guidance showed complete recovery of tinnitus and no more rhythmic movements of the muscles. Electromyography findings before and after botulinum toxin injection were also demonstrated.
