title: [Treatment of spasmodic dysphonia with botulinum toxin].
abstract: Spasmodic dysphonia is a focal laryngeal dystonia, a rare form of dystonia. Videostroboscopy, acoustic analysis, computerized voice analysis and over all electrophysiological analysis allow for the study of the different muscles involved in this dysphonia. There are two types of spasmodic dysphonia: adductor spasmodic dysphonia and abductor spasmodic dysphonia. The most efficient therapy nowadays is the injection of botulinum toxin into the thyroarytenoid muscle under fiberoptic visualization. We report 6 patient's cases of spasmodic dysphonia that we have been treating for about 2 years by direct injection of botulinum toxin in the vocal cords.
