Botulinum toxin injection for objective tinnitus from palatal myoclonus: a case report.

ABSTRACT

Objective tinnitus may be caused by many etiologies-palatal myoclonus being one of them. We report one patient of voluntary palatal myoclonus presenting with objective tinnitus treated with botulinum toxin injection. Five units of botulinum toxin A were injected into each side of the soft palate at the palatal muscles (levator veli palatini and tensor veli palatini muscle). The tinnitus disappeared within two days of injection and no side effect was observed.
