Cricoarytenoid arthritis: a cause of laryngeal obstruction

Cricoarytenoid arthritis, principally as a result of long-standing rheumatoid arthritis, is a disorder that may present to the emergency physician with a number of symptoms and signs referable to the larynx. The presentation of this disorder as acute laryngeal obstruction and collapse is uncommon. It is important to recognize early cricoarytenoid joint involvement and not mistakenly diagnose mild cases as asthma or psychoneurosis. The use of steroids in mild cases has been beneficial at times, but progressive airway obstruction and fatalities have occurred during their administration.
