PALATAL myoclonus is a neurologic symptom complex, which apparently occurs with sufficient frequency to be of interest to the otolaryngologist. This obscure phenomenon consists in clonic contractions of one or more of the muscles attached to the eustachian tube and soft palate and a synchronous ticking noise easily audible to both patient and observer. The contractions are not rhythmic, as a rule, and their rate varies in individual cases from as few as 80 to 140 or 150 per minute. They may appear either as a small dimpling of the soft palate or as a complete elevation of one or both palatal arches and uvula. The tinnitus is best described as a ticking or clicking noise and can be simulated by the snapping of one finger nail over another. The sound may be heard at distances varying from that of direct contact with the patient's ear to several feet. Nasopharyngoscopic
