Description
Summary:REASONS FOR PERFORMING STUDY: To investigate laryngeal function in cases of recurrent laryngeal neuropathy pre‐ and post laryngoplasty (LP) using dynamic respiratory endoscopy (DRE). OBJECTIVES: To compare the rima glottidis area during DRE pre‐ and post LP; document all forms of dynamic upper airway obstruction (DUAO) pre‐ and post LP and investigate the relationship between post operative abduction at rest and exercise. STUDY DESIGN: Prospective case series. METHODS: Thoroughbred racehorses with pre‐ and post LP DRE were included. Left‐to‐right arytenoid cartilage angle ratios and rima glottidis area ratios were used to quantify laryngeal function during rest and exercise, pre‐ and post LP. RESULTS: In 35 horses, mean pre‐LP ratios were greater during rest (left‐to‐right quotient angle ratio [LRQ] 0.76 ± 0.13; left‐to‐right arytenoid ratio [LRR] 0.72 ± 0.14; rima glottidis area ratio [RGA] 0.40 ± 0.10) than exercise (LRQ 0.39 ± 0.16, P
