儿童喉气管狭窄的治疗

分析19年来42例儿童后天性喉气管狭窄，年龄自15个月到14岁，平均8岁。主要病因有气管切开术后；喉气管外伤；复发性喉乳头状瘤术后；气管内插管等。全部病例狭窄严重，依靠气管切开呼吸。采用不同的喉气管重建术。结果40例病人经1～18年随访，36例（90．0％）拔除气管套管，治愈。结论：①提高气管切开术技术，可以减少儿童喉气管狭窄发病率；②3岁以上儿童可以进行喉气管重建术；③手术方式的选择必须根据喉气管狭窄病变而定。

Treatment of laryngotracheal stenosis in children

The experience of surgical treatment on 42 children with acquired laryngotracheal stenosis was reported. There were 31 males and 11 females ranging in age from 15 months to 10 years. The reason for the formation of laryngotracheal stenosis included tracheotomy (21 cases), laryngotracheal trauma (13 cases), recurrent laryngeal papillomas (4 cases) and endotracheal intubation (4 cases). All patients were tracheotomized.Various laryngotracheal reconstructions were used for these patients depending on the pathologic changes in the larynx and trachea. 40 patients were followed-up for 1 to 18 years, among them, 36 (90% ) were cured. Our finding indicated that skilled tracheotomy was the key to the prevention of laryngotracheal stenosis in children.
