Paradoxical vocal cord motion (PVCM) is a condition characterized by abnormal adduction of the vocal cords during inspiration. Diagnosis is often challenging owing to its heterogeneous presentation. Nocturnal symptoms are relatively uncommon. Associated comorbidities include gastroesophageal reflux disease or laryngopharyngeal reflux, allergic sinus disease, and possibly obstructive sleep apnea (OSA).We report two cases of PVCM presenting with predominant nocturnal symptoms owing to coexisting OSA.
