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.engAdultBotulinum Toxin Type A --therapeutic useHumansMaleMyoclonus --complicationsNeuromuscular Agents --therapeutic useTinnitus --drug therapyCase Reports
