Right-sided laryngeal dysfunction in a horse.
A two year old Thoroughbred colt was presented after a clinical diagnosis of right sided laryngeal hemiplegia had been made. On endoscopic examination the right arytenoid cartilage was immobile during respiration while the left moved normally. Post-mortem examination revealed an abnormal shape of the cricoid and thyroid cartilages which resulted in absence of the right cricothyroid articulation. The defect was thought to be congenital in origin.
