## Overview Vocal fold collapse is inward collapse of the vocal fold during exercise, often accompanying laryngeal hemiplegia. Atrophy of the thyroarytenoideus muscle contributes. It adds to airway obstruction and causes exercise-induced respiratory noise that worsens with speed. Dynamic endoscopy diagnoses it. Treatment may include ventriculocordectomy (vocal-fold removal) along with tie-back surgery. ## Causes Often secondary to recurrent laryngeal neuropathy. ## Diagnosis Dynamic overground or treadmill endoscopy. ## Treatment Ventriculocordectomy, frequently combined with laryngoplasty. ## Recovery and Prognosis Good improvement in noise and airflow with appropriate surgery. ## Prevention None specific.
exercise-induced respiratory noise; worsens with speed; diagnosed on dynamic endoscopy; may need vocal-fold surgery with tie-back
