A modified castellated laryngofissure procedure (castellated laryngofissure, vocal fold resection, and bilateral arytenoid lateralization) was performed on 12 dogs with bilateral laryngeal paralysis. Clinical signs of airway obstruction were assessed and a pulmonary function test (tidal breathing flow volume loop) was used to evaluate the severity of obstruction. The dogs were evaluated before surgery and at various periods from 4 days to 15 months after surgery. One dog died immediately after surgery and 3 dogs died due to nonrelated or unknown causes 1, 9, and 11 months after surgery. Clinical signs of upper airway obstruction disappeared or decreased in severity in the 11 dogs that recovered from surgery. Tidal breathing flow volume loop values were normal in 7 of 10 dogs evaluated within 5 to 189 days after surgery. The modified castellated laryngofissure procedure provided successful long-term relief of upper airway obstruction associated with bilateral laryngeal paralysis.
对12只双侧喉麻痹犬实施改良城堡式喉裂开术（城堡式喉裂开、声带切除术及双侧杓状软骨外移术）。评估气道阻塞的临床体征，并采用肺功能测试（潮气呼吸流速容量环）评估阻塞的严重程度。在手术前以及术后4天至15个月的不同时间段对犬进行评估。1只犬术后立即死亡，3只犬分别在术后1、9和11个月因无关或不明原因死亡。从手术中恢复的11只犬上气道阻塞的临床体征消失或严重程度减轻。术后5至189天接受评估的10只犬中，7只的潮气呼吸流速容量环值正常。改良城堡式喉裂开术成功实现了与双侧喉麻痹相关的上气道阻塞的长期缓解。
