Vocal cord dysfunction is episodic impaired function of vocal folds causing an obstructed airway. Also known as inducible laryngeal obstruction, paradoxical vocal fold movement, episodic laryngeal dyskinesia, and vocal cord adduction, the vocal folds are pulled together upon inhalation, narrowing the aperture and creating difficulty inhaling. To a lesser extent, the patient may experience difficulty exhaling.
 
Vocal cord dysfunction is characterized by inspiratory stridor, dyspnea, tightness of throat, dysphonia, cough, hoarseness, and choking sensation. Accompanying signs and symptoms may include gastroesophageal reflux (GERD), rhinosinusitis, and difficulty swallowing. It may be associated with severe asthma and/or triggered by anxiety, exercise, exposure to irritants, sinus infection, or gastrointestinal reflux. This condition is not uncommon among student athletes. In children, vocal cord dysfunction is more common in girls than boys.

Management may involve deep breathing and muscle relaxation exercises, respiratory retraining, stress management counseling, and speech therapy.
