Irritable Larynx Syndrome with Dyspnea

ABSTRACT

An irritable larynx syndrome is characterized by a sudden episodic dyspnea and dysphonia that is difficult to diagnose, and patients are often treated unnecessarily and/or too much. A correct diagnosis can be made by monitoring the larynx closing in the reversed direction during inhalation and posterior chink with videolaryngoscopy and by measuring a decrease in air flow volume during inhalation with a lung function test. Patients can be effectively treated with thorough differential diagnosis. Medications targeting precipitating factors, physical therapy sessions to improve abnormal larynx movement, counseling to reduce patients'anxiety rising from dyspnea, and etc. can effectively alleviate symptoms.
