Bilateral Vocal Fold Medialization: A Treatment for Abductor Spasmodic Dysphonia

Abductor spasmodic dysphonia, a difficult-to-treat laryngologic condition, is characterized by spasms causing the vocal folds to remain abducted despite efforts to adduct them during phonation. Traditional treatment for abductor spasmodic dysphonia—botulinum toxin injection into the posterior cricoarytenoid muscle—can be both technically challenging and uncomfortable. Due to the difficulty of needle placement, it is often unsuccessful. The purpose of this investigation is to present a previously undescribed treatment for abductor spasmodic dysphonia—bilateral vocal fold medialization.
