Endoscopy provides visual examination of the upper airway from the nasal passage to the end of the trachea. This allows the veterinarian to assess and evaluate the upper-airway for conformational, infectious, neo-plastic, traumatic, or neurologic abnormalities.

Endoscopy can accompany any pre-purchase/sale examination giving the buyer information needed on the status of the horse’s upper airway. Lesions or abnormalities within the upper airway can hinder any performance horse’s ability to perform at competitive levels. An endoscopic examination can determine what the cause of abnormality is and what steps will need to be made to correct the underlying problem. Endoscopy can also provide visual examination of the guttural pouches, and flushing of the guttural pouches can be performed more accurately with the visual aid of an endoscope.
