Three children with tracheomalacia had tracheal reinforcement with free three-quarter circumference ring grafts of autologous cartilage taken from the costal margin. A low cervical manubrium-splitting approach gave excellent access to the anterior mediastinum and the intrathoracic trachea in two children. The first child, a neonate with oesophageal atresia (OA) and tracheo-oesophageal fistula (TOF), had 11 grafts to support the whole of the trachea from the cricoid to the carina and never required a tracheostomy. For the first 5 years she had frequent pneumonic episodes and on one occasion bilateral pneumothoraces. These episodes and radiographic lung hyperinflation, attributed to distal bronchomalacia, have reduced spontaneously in frequency and severity. At 9 years of age she has a well-supported trachea with palpable cartilage rings in the cervical segment. The trachea has grown to approximately 75% of expected normal size for her age. Another child with tracheomalacia related to innominate-artery compression and who presented with 'dying episodes' was completely relieved and resumed a normal life without a tracheostomy following insertion of four grafts to the intrathoracic trachea. He remains well and symptom-free 8 months postoperatively. A third child had cartilage-graft reinforcement of the lower cervical trachea, including the tracheostomy site, to achieve tracheostomy closure at 16 months of age. Five years later he continues to have a well-supported trachea showing acceptable growth. However, he has ongoing evidence of tracheo-bronchomalacia presenting as expiratory wheezing, lung hyperinflation, and pneumonic episodes that are diminishing spontaneously with growth. Our experience, limited to three children, recommends primary tracheal reinforcement with autologous free costal-cartilage grafts for tracheomalacia in the neonate and young infant. This procedure and the anterior mediastinal approach are well-tolerated, providing instant tracheal support, removing the need for a tracheostomy, and allowing the child's rapid return to the family. Long-term follow-up, presently 9 and 5 years in two children originally presenting with OA and TOF, indicates adequate tracheal growth and an aesthetically acceptable appearance. It is relevant to prognosis that relief of the life-threatening tracheal component exposed the full extent of the bronchial cartilaginous weakness, which has significantly detracted from the quality of life for these two children with OA and TOF-related tracheomalacia.
三名患有气管软化症的儿童接受了取自肋缘的自体软骨四分之三周长游离环形移植气管强化术。低位颈部胸骨劈开入路为两名儿童提供了极佳的前纵隔和胸内气管显露。第一名儿童是一名患有食管闭锁(OA)和气管食管瘘(TOF)的新生儿,接受了11次移植以支撑从环状软骨到隆突的整个气管,从未需要气管造口术。在最初的5年里,她频繁发生肺炎,有一次还出现双侧气胸。这些发作以及归因于远端支气管软化的放射影像学上的肺过度充气,在频率和严重程度上都自发减轻。9岁时,她的气管得到了良好支撑,颈部段可触及软骨环。气管已生长至其年龄预期正常大小的约75%。另一名因无名动脉压迫导致气管软化症并出现“濒死发作”的儿童,在胸内气管植入4次移植后完全缓解,无需气管造口术并恢复了正常生活。术后8个月他仍状况良好且无症状。第三名儿童对下颈部气管,包括气管造口部位进行了软骨移植强化,以便在16个月大时关闭气管造口。5年后,他的气管仍得到良好支撑,显示出可接受的生长情况。然而,他仍有气管支气管软化的证据,表现为呼气性哮鸣、肺过度充气和肺炎发作,随着生长这些症状正在自发减轻。我们仅针对三名儿童的经验表明,对于新生儿和幼儿的气管软化症,推荐采用自体游离肋软骨移植进行原发性气管强化。该手术和前纵隔入路耐受性良好,能立即提供气管支撑,无需气管造口术,并使患儿能迅速回到家庭。目前对最初患有OA和TOF的两名儿童分别进行了9年和5年的长期随访,结果表明气管生长充足且外观可接受。与预后相关的是,危及生命的气管问题得到缓解后,支气管软骨薄弱的全貌暴露出来,这显著降低了这两名患有OA和TOF相关气管软化症儿童的生活质量。
