Recurrent Laryngeal Neuropathy, Roarers
|Prosthetic laryngoplasty (tie-back surgery)||The most common surgical procedure involving "tying back" the paralyzed cartilage so that it remains in an open position. It can be performed while the horse is under standing sedation or general anesthesia. The procedure is the most common treatment for horses with RLN and is usually effective for restoring free airflow, but there is a risk of recurrence if the sutures tear out or if the tissues are stretched during muscle movement around the larynx.|
|Ventriculectomy/Cordectomy||A surgical procedure involving the removal of the ventricle and vocal cord, to widen the airway and may be performed by itself or alongside a prosthetic laryngoplasty. There are two techniques involved---via an incision under the jaw or by using a laser passed through an endoscope up the horse's nostril. When the laser is used, the procedure can be performed while the horse is under standing sedation. When an incision is made in the jaw, then general anesthesia is necessary.|
|Arytenoidectomy||A surgical procedure involving the removal of the paralyzed arytenoid cartilage. It is usually the choice for horses with an infected arytenoid cartilage or who had previous had a tie-back surgery which was unsuccessful. The procedure requires general anesthesia and is done through an incision into the throat.|
|Neuromuscular Pedicle Graft||A surgical procedure that re-innervates the muscles that control abduction of the arytenoid cartilage. Horses which have previously received a tie-back procedure are unable to have this procedure due to loss of nerve function.|
