Videoendoscopy allows direct visualisation of the upper airway, including the nasal passages, the pharynx, larynx and guttural pouches, and the lower airway, including the trachea and main bronchi. Images can be recorded and saved. Video recordings of the movement of the larynx can be acquired and evaluated for sales purposes.

Common signs in horses that suggest the need for endoscopy of the airway include:

  • An abnormal noise at rest or during exercise 
  • Nasal discharge that does not resolve following standard treatment
  • Recurrent coughing or a coughing problem that does not resolve with standard treatment 
  • Nosebleeds
  • Poor performance 
  • Increased respiratory effort during exercise or unusually prolonged recovery after exercise
