After initial treatment of severe laryngotracheal stenosis (LTS), we evaluated subsequent airway function. Five children between 2 and 11 years were treated previously for severe LTS by T-tube stenting. One case underwent subsequent laryngotracheal reconstruction. All patients demonstrated dyspnea, the severity of which increased with age and duration of time after completion of stenosis treatment. In the most severe cases, magnetic resonance imaging and endoscopy revealed secondary subglottic stenosis. Ventilatory function tests disclosed obstruction of both extrathoracic and pulmonary origin. These findings raise questions regarding the treatment of the initial stenosing tissue and of the secondary stenoses.
在对严重喉气管狭窄（LTS）进行初始治疗后，我们评估了后续的气道功能。5名年龄在2至11岁之间的儿童此前接受了T形管支架置入术治疗严重LTS。其中1例随后接受了喉气管重建术。所有患者均表现出呼吸困难，其严重程度随年龄以及狭窄治疗完成后的时间延长而增加。在最严重的病例中，磁共振成像和内窥镜检查显示存在继发性声门下狭窄。通气功能测试揭示了胸外和肺部来源的梗阻。这些发现引发了关于初始狭窄组织和继发性狭窄治疗的问题。
