Spasmodic dysphonia is a voice disorder characterized by involuntary voice breaks during speech. Adductor spasmodic dysphonia is most common and characterized by strained and strangled voice breaks. The current standard of treatment of therapy for adductor spasmodic dysphonia is chemodenervation of thyroarytenoid muscle with botulinum toxin(Botox). However, Botox is a temporary treatment with each injection lasting approximately 3 months on average and require repeated injections. In this study, we report our experience with surgical treatment for adductor spasmodic dysphonia. In this procedure, the thyroarytenoid branch and lateral cricoarytenoid branch of recurrent laryngeal nerve is selectively denervated unilaterally, and its distal nerve stump of thyroarytenoid branch is reinnervated with branch of the usa cervicalis nerve. And lateral cricoarytenoid muscle partial myotomy was done unilaterally. After 6 months of treatment, voice fluency had improved and no period of breathiness or dysphagia was noted.
