Laryngeal Ventral Webbing Laryngeal Keel

The laryngeal keel is a sialastic implant that can be placed through the ventral thyroid cartilage of the larynx so that its "keel" extends into the larynx right in front of the denuded laryngeal mucosa (raw area) created after the ventral web is removed and the glotic opening is cleared. The function of the keel is to prevent any granulation tissue that develops from the right, left and ventral sides of the larynx from fusing and obstructing the opening. As this granulation tissue matures, contracts and is covered by epithelium, the laryngeal lumen is left open.

Facial nerve paralysis is a complication that may worry about. It is rare but when it does occur it is a non clinical issue. The third eyelid does a good job of lubricating the eye and the slight upper lip drop is almost non noticeable. The relief from the pain and discomfort of the disease more than compensates the animal and owner for any facial nerve issues that may occur.
