A Child of Palatal Myoclonus Tinnitus Treated with Intraoral Injection of Botulinum Toxin / 대한이비인후과학회지

ABSTRACT

Palatal myoclonus (palatal tremor) was reported to be presented with a sole symptom of objective pulsating tinnitus and could be controlled by botulinum toxin injection alone. However, there were 3 cases reported in Korea of palatal myoclonus tinnitus controlled with botulinum toxin injection through the dual administration route of the mouth and nasal cavity. We present an 11-year-old boy of essential palatal myoclonus tinnitus, which was controlled by intraoral botulinum toxin injection to the tensor veli palatini muscle alone. Intraoral injection of botulinum toxin to the anatomical location of tensor veli palatini muscle with the guidance of electromyography was effective and safe for the child of objective tinnitus caused by palatal myoclonus.
