Laryngeal dysfunction, previously referred to as vocal cord dysfunction or paradoxical vocal cord movement, is characterized by inappropriate, transient, and reversible narrowing of the larynx in response to external triggers, without any structural or neurological defects. This condition can manifest in various clinical ways and can be mistaken for other respiratory diseases, such as asthma. It is crucial to accurately recognize and diagnose laryngeal dysfunction to ensure the provision of appropriate treatment. Laryngoscopy with provocation, which is a standard tool for the diagnosis of laryngeal dysfunction, has been designated as a new medical technology in Korea in July 2022. In this review, we discuss the concept, epidemiology, diagnosis, and treatment of laryngeal dysfunction as well as introduce the diagnostic procedure using laryngoscopy with provocation.
