Audiological investigation of palatal myoclonus.

Abstract

Palatal myoclonus, the rapid rhythmic contraction of palatal muscles, is a rare neurological disorder with many etiologies. Although most disease processes associated with this disorder affect the cerebellum, the auditory symptoms are often the first clue to diagnosis. Existing literature was reviewed in terms of auditory symptoms, pathophysiology, audiologic diagnostic procedures and rehabilitative strategies. In addition, a case study of a 34-yr-old woman who has had this highly peculiar degenerative disorder for over 20 yrs was described. Implications for appropriate rehabilitation strategies were addressed and the importance of comprehensive management was stressed.
