Palatal myoclonus


Palatal myoclonus is a rapid spasm of the palatal muscles, which results in clicking or popping in the ear. The movements of the palate vary in rate between 40 and 200 beats per minute. Chronic clonus is often due to lesions of the central tegmental tract. Uniquely, the clicking noise does not subside when the patient sleeps.
When associated with eye movements, it is known as oculopalatal myoclonus
