Vocal cord dysfunction (VCD) is a syndrome characterized by paroxysms of glottic obstruction due to true vocal cord adduction resulting in symptoms such as dyspnea and wheezing.The disorder is often misdiagnosed as asthma leading to serious consequences.Pulmonary function testing with a flow-volume loop and flexible laryngoscopy are valuable diagnostic tests for confirming vocal cord dysfunction.Laryngoscopy is the gold standard for diagnosis of VCD.Treatment of acute episodes includes reassurance,breathing instruction,and use of a helium and oxygen mixture (heliox).Long-term management strategies include treatment for symptom triggers and speech therapy.
