Upper Airway Endoscopy
An endoscope (a narrow flexible tube containing a camera at its end) is passed through the horse’s nose to visualize the pharynx, larynx, trachea, and guttural pouches. When a horse exhibits an intolerance to or has problems breathing during exercise an upper airway endoscopy should be performed to correctly diagnose the cause
and recommend proper treatment.
An endoscopic examination may be performed during pre-purchase examinations, as well as to investigate cases of chronic nasal discharge or nosebleeds.
