Abstract

Paradoxical vocal fold motion (PVFM) is a rare disorder, characterized by episodic glottic obstruction in which the vocal folds are adducted on respiration. The disorder may aggravate airway obstruction and result in respiratory failure; therefore, a proper diagnosis by the otolaryngologist is critical to subsequent treatment. A review of literature shows that the effective treatment is psychotherapy, breathing education, biofeedback, anti-reflux medications, and most importantly, botulinum toxin injection to both vocal folds. We report a case with PVFM, effectively treated with above modalities.
