作者追随观察八年来采用保守疗法扩张治疗的严重声门下狭窄气管切开患儿25例,其中14例拔管成功,平均戴管三年;5例未能拔管;6例死于气管切开术后并发症。鉴于保守治疗疗程长、痛苦大、花费多及死亡率高,作者探索出一种新的手术疗法,这种手术方法在动物实验(16只成年猴)中获得成功,并通过幼猴(5只)得以证实此手术对喉之成长无影响。作者继用此法给两例声门下狭窄患儿进行手术治疗,均取得较好的近期效果(追随时间分别为3个月及7个月)。 The authors followed 25 cases of severe subglottic tracheostomy treated with conservative therapy for eight years, of whom 14 had successful extubation, wearing an average of three years; 5 failed to extubate; and 6 died of tracheotomy Postoperative complications. In view of the long duration of conservative treatment, painful, costly and high mortality, the authors explored a new surgical approach that succeeded in animal experiments (16 adult monkeys) ) To confirm that this surgery has no effect on the growth of larynx. The authors follow this method for two cases of sonicated stenosis in children undergoing surgical treatment, have achieved good near-term results (follow-up time was 3 months and 7 months).
