Tracheal collapse is a chronic, progressive, irreversible disease of the trachea, or windpipe, and lower airways (mainstem bronchi collapse).The trachea is a flexible tube and, similar to a vacuum cleaner hose. It has small rings of cartilage that help keep the airway open when the dog is breathing, moving or coughing.racheal collapse is a chronic, progressive, irreversible disease of the trachea, or windpipe, and lower airways (mainstem bronchi collapse).
Tracheal stenosis is narrowing of the trachea, or windpipe. Tracheal stenosis causes shortness of breath, which is made worse during exercise.Noisy breathing can be heard when tracheal stenosis is severe.1  Scar formed from the tip of a breathing tube.reatment for tracheal stenosis enlarges the size of the airway, thus making breathing easier. In the operating room bronchscopy is performed with the patient asleep. Sometimes a laser is used to cut the narrowed portion of the airway from the inside.
