A noncurrent prospective study of nonworking horses with arytenoid chondropathy was conducted to confirm a clinical impression that horses with unilateral chondropathy and accompanying lesions had a poorer prognosis after arytenoidectomy than horses with bilateral or uncomplicated unilateral chondropathy. Surgical failure was defined as death, euthanasia, permanent tracheostomy, or reoperation. Survival to surgical failure and clinical improvement data were compared between horses with and without accompanying lesions treated by arytenoidectomy. The probability of surgical failure was significantly higher and times to surgical failure were significantly shorter for horses with unilateral chondropathy and accompanying lesions than for horses with bilateral or uncomplicated unilateral chondropathy. Clinical improvement at the median follow-up time of 6 months was significantly less likely in horses with than without accompanying lesions. Horses with endoscopic evidence of inflammation and paralyzed opposite cartilage were significantly less likely to improve clinically than horses with pharyngeal cicatrix.
对患有杓状软骨病的非工作马进行了一项非同期前瞻性研究，以证实一种临床印象，即患有单侧软骨病及伴随病变的马在杓状软骨切除术后的预后比患有双侧或单纯性单侧软骨病的马更差。手术失败定义为死亡、安乐死、永久性气管造口术或再次手术。比较了接受杓状软骨切除术治疗的有或无伴随病变的马的手术失败生存率和临床改善数据。与患有双侧或单纯性单侧软骨病的马相比，患有单侧软骨病及伴随病变的马手术失败的概率显著更高，手术失败的时间显著更短。在中位随访时间6个月时，有伴随病变的马临床改善的可能性明显低于无伴随病变的马。有内镜检查证据显示有炎症且对侧软骨麻痹的马，其临床改善的可能性明显低于有咽部瘢痕的马。
