Plain-English summary
A group of dogs with laryngeal paralysis, a condition that can cause breathing difficulties, underwent a surgical procedure called left partial arytenoidectomy using a laser. This technique helped widen their airway, improving their ability to breathe. After the surgery, most dogs showed good respiratory function and had no major complications. While two dogs developed aspiration pneumonia a year later, the overall results indicated that this laser surgery is a promising option for treating laryngeal paralysis in dogs.

Abstract
OBJECTIVES: To evaluate the clinical outcome of left partial arytenoidectomy by video-assisted laser diode photoablation as a surgical treatment for canine laryngeal paralysis (LP). STUDY DESIGN: Case series. ANIMALS: Dogs with bilateral LP (n=20). METHODS: After endoscopic diagnosis of bilateral LP, left partial arytenoidectomy was performed by photoablation of arytenoid cartilage tissue using a diode laser (600 microm diameter, 15 W power, 980 nm wave length) to increase the width of the rima glottidis. Outcome was evaluated endoscopically (1 and 6 months) and clinically (1, 6, and 12 months). RESULTS: No substantial complications occurred during photoablation or in the immediate postoperative period. Postoperative width of the rima glottidis ranged from 6 to 10 mm at its widest aspect. At 1 month, respiratory function after walking and short running appeared good. Clinical and endoscopic examination revealed good outcome at 1 and 6 months. At 6 months, there was no evidence of hypertrophic scar, hypertrophic granulation tissue, or stricture of the laryngeal glottis in any dog. Two dogs developed aspiration pneumonia after 12 months. CONCLUSIONS: Partial arytenoidectomy using video-assisted diode laser photoablation appears to be an effective technique for treating LP. CLINICAL RELEVANCE: Partial arytenoidectomy by diode laser photoablation should be considered as an alternative technique for treatment of canine LP.
