Laryngoscopy.
The larynx normally functions in vocalization, deglutition, and respiration. There is no substitute for direct laryngoscopy in animals suspected of having laryngeal disease. Clinical signs that should alert the veterinarian include cough, choking while eating or drinking, exertional cyanosis and syncope, noisy breathing, inspiratory dyspnea, stridor, and significant change in sound production. Controlled anesthesia is mandatory for animals with suspected laryngeal disease because many of these patients have compromised respiratory function. Laryngoscopy is used to note abnormalities in the shape, color, and motility of the larynx with special attention to correlating the movement of the arytenoid cartilages and vocal folds with the respiratory cycle.
