Abstract

Dysphonia Spasmodic dysphonia Myoneurectomy Surgical treatment of spasmodic dysphonia Abductor spasmodic dysphonia
To discuss the utility and outcomes of bilateral myoneurectomy for treatment of abductor spasmodic dysphonia. Bilateral myoneurectomy is a known treatment option for patients with adductor spasmodic dysphonia. Its use for treatment of abductor spasmodic dysphonia, however, has not been documented previously. In this case report, treatment and long-term outcomes of abductor spasmodic dysphonia with bilateral myoneurectomy are discussed. A 50-year-old male presented with abductor spasmodic dysphonia. His initial Voice Handicap Index-10 (VHI-10) score was 29, and he had breathy breaks during 60 series. He had no improvement in vocal quality after 6 botulinum toxin injections over 21 months. He underwent staged bilateral posterior cricoarytenoid partial myoneurectomy, with the left posterior cricoarytenoid myoneurectomy performed 33 months after presentation and right posterior cricoarytenoid myectomy 11 months later. Eight years postoperatively, his VHI-10 score was 12. During postoperative 60 series, the patient demonstrated few breathy breaks. Overall, the patient reports improved quality of life and satisfaction with his voice. This is the first report of a long-term follow-up data for bilateral, endoscopic, partial posterior cricoarytenoid muscle myoneurectomy to treat refractory abductor spasmodic dysphonia. Long-term VHI-10 results suggest improvement of symptoms, despite mild difficulty with 60 series. While botulinum toxin therapy is the mainstay of management for abductor spasmodic dysphonia, surgical treatment is a potential alternative at least for refractory cases.
