Educational Pearls:

• Vocal cord dysfunction can mimic other causes of stridor, such as asthma and upper airway obstruction.
• Patients are often very anxious because of the difficulty of inspiration.
• The definitive diagnosis is laryngoscopy that must be done by a pulmonologist.
• The treatment is general reassurance, asthma medications will not help. CPAP and heliox can be used to help with the stridor.
• Benzodiazepines can be used to reduce the associated anxiety.
