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.
痉挛性发音障碍是一种局灶性喉肌张力障碍，是肌张力障碍的一种罕见形式。频闪喉镜检查、声学分析、计算机语音分析以及整体电生理分析有助于研究参与这种发音障碍的不同肌肉。痉挛性发音障碍有两种类型：内收型痉挛性发音障碍和外展型痉挛性发音障碍。目前最有效的治疗方法是在纤维光学可视化下将肉毒杆菌毒素注射到甲杓肌中。我们报告了6例痉挛性发音障碍患者的病例，我们通过在声带中直接注射肉毒杆菌毒素对其进行了约2年的治疗。
