摘要声门下气管闭锁是最严重的气管狭窄类型，常导致患者气管切开套管难以拔除，严重影响其生存质量甚至生命危险。本文通过回顾性分析10例首都医科大学附属北京天坛医院收治的气管闭锁患者病例资料，分析并总结其经逆行穿刺再通后T管置入术治疗取得较好疗效的经验，以提高支气管镜医生对声门下气管闭锁治疗能力。

abstractsCotton-Myer Ⅳ subglottic airway atresia is the most severe type of tracheal stenosis, often leading to long-term in-dwelling tracheotomy cannula in patients, which can severely affect their quality of life and even be life threatening. In order to improve the treatment ability of bronchoscopy physicians for airway atresia, this article retrospectively analyzed 10 cases of subglottic airway atresia in Beijing Tiantan Hospital, Capital Medical University, and summarized the experience of achieving better results by Montgomery T-tube implantation after reverse puncture airway recanalization.
