Stage III laryngeal collapse is defined as the collapse of the corniculate processes of the arytenoid cartilages and the destructuration of the dorsal portion of the rima glottidis. The primary cause is chronic upper airway obstruction, and the condition is often present in brachycephalic dogs. The treatment is still controversial; the patients are generally treated with a permanent tracheostomy. This article reports the authors' experience with 16 dogs affected by stage III laryngeal collapse treated with subtotal epiglottectomy and the ablation of unilateral arytenoid cartilage. Before the surgery, all of the dogs underwent an effort test to classify the clinical severity of the disease and an endoscopic examination of the airways to determine the stage of severity of the laryngeal collapse. One month after surgery, the effort test was repeated in order to evaluate the clinical outcome. One year after surgery, the owners of 12 patients rated their dogs as follows: excellent in five cases, good in five cases, and fair in two cases. According to this pilot study, epiglottectomy associated with the photoablation of unilateral arytenoid cartilage increases airway flow, and thus may be considered a valid surgical procedure to treat dogs affected by grade III laryngeal collapse.
III 期喉塌陷的定义为杓状软骨小角状突的塌陷以及声门裂背侧部分的结构破坏。主要病因是慢性上呼吸道梗阻，这种情况常见于短头犬。治疗方法仍存在争议；患者通常接受永久性气管切开术治疗。本文报告了作者对 16 只受 III 期喉塌陷影响的犬进行次全会厌切除术和单侧杓状软骨切除术的经验。手术前，所有犬均接受运动试验以对疾病的临床严重程度进行分级，并接受气道内镜检查以确定喉塌陷的严重程度阶段。手术后 1 个月，重复进行运动试验以评估临床结果。手术后 1 年，12 只犬的主人对其犬的评价如下：5 例为优秀，5 例为良好，2 例为中等。根据这项初步研究，会厌切除术联合单侧杓状软骨光凝术可增加气道流量，因此可被视为治疗 III 级喉塌陷犬的一种有效手术方法。
