The first procedure entailed CO<sub>2</sub> laser photoablation of collapsed tracheal rings and dilatation. The second procedure, performed 6 to 8 weeks later, involved ablation of residual structural obstruction, removal of granulation tissue, and intralesional corticosteroid injection. Perioperative patient and lesion characteristics and results of treatment were assessed.</p> </sec> <sec id="lary23945-sec-0004" sec-type="section"> <title>Results</title> <p>There were 22 males and 18 females, and mean age at first treatment was 59 years. There were 17 cases of scarring at the postero‐lateral tracheal groove (trachealis blunting), and 22 patients had age‐adjusted Charlson comorbidity scores greater than 4. All patients without trachealis blunting were successfully managed endoscopically, with only one patient requiring one additional endoscopic treatment. Seven patients with trachealis blunting needed additional treatment, and four patients had tracheal resection (<italic>P</italic> = 0.013). All patients were decannulated, and 75% of patients achieved good dyspnea outcomes. Patients with low morbidities were significantly more likely to achieve good dyspnea outcomes (<italic>P</italic> < 0.027). There were no treatment‐related worsenings of voice or swallowing.</p> </sec> <sec id="lary23945-sec-0005" sec-type="section"> <title>Conclusions</title> <p>ERT is an effective minimally invasive treatment for intubation‐related lambdoid tracheal stenosis. It achieves a successful outcome while avoiding the risks associated with open surgery. We recommend its more widespread use for treating patients with this condition.</p> </sec> <sec id="lary23945-sec-0006" sec-type="section"> <title>Level of Evidence</title> <p>4. <italic>Laryngoscope</italic>, 2012</p> </sec> </abstract>
