Abstract

The effectiveness of one or two suture prothesis in performing laryngoplasty was compared. Forty-six horses treated for left laryngeal hemiplegia at North Carolina State University, College of Veterinary Medicine (NCSU-CVM) between January 1987 and April 1991 were included in the study. Thirty-seven of the horses were treated with two sutures, while nine were treated with one suture. All horses, after recovering from general anesthesia, were sedated the following day and were subjected to a transendoscopic neodymium: yttrium aluminum garnet (Nd:YAG) laser ablation of the left laryngeal ventricle. Ability to perform after treatment relative to before treatment, reduction or elimination of respiratory noise, owner or trainer satisfaction, were compared for the two suture prosthetic procedures using chi-squared test or Fisher's exact test. No statistical significant differences were found for performance, reduction of noise, and owner or trainer satisfaction. The use of one or two sutures seemed to have no effect on the effectiveness of prosthetic laryngoplasty procedure followed by Nd:YAG ventricular ablation.
