Spasmodic dysphonia (SD) is a focal dystonia of the larynx. Adductor spasmodic dysphonia (ADSD) involves the laryngeal adductor muscles, and symptoms of vocal roughness, staccato-like sounds, and stops in phonation. Abductor spasmodic dysphonia (ABSD) affects the laryngeal abductor muscles, resulting in a breathy or whispered voice quality and voice breaks. SD has a significant impact on the quality of life. This article discusses symptoms of SD and the standard treatment of SD.
