Paper Abstract

A telephone survey was conducted to assess the efficacy of laryngoplasty surgery followed by Nd:YAG laser laryngeal ventricular ablation. Forty-three horses were included in the study that were treated at North Carolina State University, College of Veterinary Medicine (NCSU- CVM) January 1987 and September 1990. Questions asked of the owners or trainers of the horses related to complications that the horses may have had since leaving the hospital, ability to perform after treatment relative to before treatment, how respiratory noise after treatment related to before treatment, results of follow-up endoscopic exams, additional surgery that may have been performed, and owner satisfaction with the procedure. Wilcoxon signed rank test was used to determine the success of the procedure. Success was defined as a reduction of noise or improvement in performance ability. Results of the test indicated that the two procedures had an effect in reducing respiratory noise (p equals 0.0001) and increasing performance (p equals 0.0017).
