title: Study of spastic dysphonia using videofiberoptic laryngoscopy.
abstract: Spastic dysphonia is a speech disorder, characterized by a "strangled voice quality," irregularly occuring phonatory arrests, and a jerky pattern of speech. This is often extremely disruptive to the patient's ability to communicate. Two cases are presented in which a new technique, videofiberoptic laryngoscopy, was employed in the study of these patients. The characteristic laryngeal behavior of this disorder is documented and recorded, particularly noting the increase in supraglottic activity and how different vocal maneuvers alter this activity.
