EQUINE | Abstracts Results Surgery was performed in 17 client‐owned animals with RLN. Reinnervation was confirmed by nerve stimulation and subsequent arytenoid abduction observed in 11 out of 12 cases between 4 and 12 months post‐operatively. Fourteen horses had exercising endoscopy before and after surgery. Nine horses had an improved exercising RLN grade, four horses had the same exercising grade and one horse had a worse exercising grade after surgery. Main limitations A sham‐operated control group was not included and follow‐up beyond 12 months and objective perfor- mance data were not obtained. Conclusions The modified first or second cervical nerve transplan- tation technique, using tunnelling and direct implan- tation of the donor nerve into the cricoarytenoideus dorsalis muscle, resulted in reinnervation in 11 out of 12 cases and improved exercising grade in 9 out of 14 horses within 12 months after surgery. http://onlinelibrary.wiley.com/doi/10.1111/evj.12788/full 14 • Equine Health Update •
