Paradoxical vocal cord motion (PVCM) is an uncommon disease characterized by vocal cord adduction during inspiration and/or expiration. It can create shortness of breath, wheezing, respiratory stridor, or breathy dysphonia. Possible etiological factors include asthma, underlying psychologic condition, gastroesophageal acid reflux disease, respiratory irritants exposure, central neurologic diseases, viral upper airway infections, and postsurgical procedures. Many treatment modalities were performed for acute attack of PVCM, including reassurance and onsite maneuvers, benzodiazepines, heliox, and so forth. We report a patient with PVCM who had stridor and dyspnea for 10 days and responded to intravenous haloperidol treatment.
