Radiofrequency Ablation in the Treatment of Idiopathic Bilateral Palatal Myoclonus: A New Indication

Abstract

Objectives:

We tested the effect of radiofrequency ablation in the treatment of palatal myoclonus refractory to other therapeutic regimens.

Methods:

A 20-year-old patient who presented with palatal myoclonus and annoying rhythmic objective clicking noise was treated with a radiofrequency generator with topical and local anesthesia in an outpatient setting.

Results:

The clicking noise was abolished within 3 to 4 days of the radiofrequency ablation. The rhythmic, jerky movements of the soft palate were confirmed to be absent 2 weeks later with electromyographic studies. The patient has been symptom-free for 6 months, and no side effects have occurred.

Conclusions:

As a new indication, radiofrequency ablation may effectively abolish abnormal movements of the soft palate and relieve associated tinnitus.
