Objective tinnitus from palatal myoclonus. Use of botulinum toxin: a case report.
نویسندگان
چکیده
Objective tinnitus can have many different etiologies, palatal myoclonus being one of the less frequent. This type of tinnitus is generated by involuntary rhythmic contraction of the soft palate, which generates an audible click for the patient and for the explorer. Botulinum toxin achieves temporary muscle paralysis through presynaptic inhibition of the acetylcholine level at the neuromuscular union. We present a patient with long-term objective tinnitus, along with this patient's response to botulinum toxin injection.

We thank Dr. Ozdogan and colleagues for their comments regarding our article on the management of palatal myoclonus with botulinum toxin.
