Abstract

Spasmodic dysphonia is a focal laryngeal dystonia that results in involuntary spasms during speech. The etiology of spasmodic dysphonia is not yet defined, but it is presumed to be a neurological abnormality of central nervous system motor function. The treatment of choice for spasmodic dysphonia is botulinum toxin injection directly at the laryngeal muscles. However botulinum toxin injection requires repeated procedures. Many different kinds of surgical treatments have been introduced but the recurrence rate is still high. So we performed myomectomy with LASER and neurectomy with specially designed electrical surgical knife which can cut recurrent laryngeal nerve branch selectively with its noble curved section. We report a case of a 43-year-old male patient with spasmodic dysphonia treated by thyroarytenoid myoneurectomy.
