Medical records of 70 horses diagnosed with left laryngeal hemiplegia that were treated by use of prosthetic laryngoplasty combined with bilateral ventriculectomy were examined. Degree of arytenoid cartilage abduction that had resulted from the prosthesis had been graded before the horse was discharged from the hospital. Follow-up information through owner/trainer questioning was acquired for 55 horses. Information concerning the type and frequency of complications, if any, was recorded, along with a determination of owner/trainer satisfaction regarding surgical results. Race records were acquired for 42 horses and were used to aid in evaluation of postoperative performance. After surgery, Thoroughbred racehorses had a much lower success rate (48%; 19 of 40 horses), determined from owner/trainer questioning, than did all breeds in the study that were not intended for racing (93%; 14 of 15 horses). Younger Thoroughbred race-horses had a better success rate (70%; 14/20) than did those > or = 3 years old (25%; 5/20). Degree of arytenoid abduction had little effect on outcome, except that horses with maximal abduction (grade 5) of the arytenoid cartilage had a higher prevalence of complications and poor correction. The 2 most prevalent complications were exercise intolerance (42%; 23 of 55 horses) and continuing noise when exercising (47%; 26 of 55 horses).
对70匹诊断为左喉偏瘫并接受喉成形术联合双侧脑室切除术治疗的马匹的病历进行了检查。在马匹出院前，对假体导致的杓状软骨外展程度进行了分级。通过询问主人/训练师获得了55匹马的随访信息。记录了并发症的类型和发生率（如有），以及主人/训练师对手术结果的满意度。获取了42匹马的比赛记录，并用于评估术后表现。手术后，通过询问主人/训练师确定，纯种赛马的成功率（48%；40匹马中的19匹）远低于研究中所有非参赛品种（93%；15匹马中的14匹）。年轻的纯种赛马成功率（70%；20匹中的14匹）高于3岁及以上的马匹（25%；20匹中的5匹）。杓状软骨外展程度对结果影响不大，只是杓状软骨最大外展（5级）的马匹并发症发生率较高且矫正效果较差。两种最常见的并发症是运动不耐受（42%；55匹马中的23匹）和运动时持续有杂音（47%；55匹马中的26匹）。
