Abnormal soft palate posturing in patients with laryngeal movement disorders.

Laryngeal movement disorders (LMDs), including spasmodic dysphonia and essential voice tremor, have been described as focal disorders affecting the muscles of the larynx. Little reference has been made to possible hyperfunction of supralaryngeal structures and/or palatal involvement. Videonasolaryngoscopic examinations of 83 patients with LMDs revealed a significantly high incidence of abnormal soft palate posturing (84%). Further associations and implications are presented.
