Upper Airway Dysfunction Associated with Collapse of the Apex of the Corniculate Process of the Left Arytenoid Cartilage During Exercise in 15 Horses

Abstract

Dynamic collapse of the apex of the left corniculate process and into the airway at the dorsal apposition between the paired arytenoid cartilages can only be diagnosed during HSTV. It is an uncommon cause of upper airway dysfunction but may affect the athletic potential of racing Thoroughbreds and Standardbreds.
