Embouchure Dystonia

Embouchure dystonia is a perioral focal task-specific disorder involving abnormal non-coordinated movements and involuntary muscle contraction. We report a 27-year-old male, professional french horn player with embouchure dystonia. While the patient was performing, involuntary contractions of depressor anguli oris and risorius muscles were observed by means of physical examination and a surface electromyographic study. His complaints were taken under control with oral clonazepam. Published studies lack adequate number of patients to understand the mechanism of embouchure dystonia and the treatment choices. But the present data supports that abnormal somatosensory reorganization may contribute to the disorder and medications for general dystonia can be used.
