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.
