All patients underwent either cold steel (107 patients) or CO<jats:sub>2<\/jats:sub> laser (32 patients) lysis of stenosis with concurrent dilation. RTFS within 2 years was 50.2% for CO<jats:sub>2<\/jats:sub> laser and 31.9% for cold steel (hazard ratio [HR] and 95% confidence interval [CI]: 1.69, 0.96\u20102.97, <jats:italic>P<\/jats:italic>\u2009=\u2009.07). In patients with no prior airway procedures, there was no difference in RTFS between laser and cold knife (<jats:italic>P<\/jats:italic>\u2009=\u2009.41). However, in patients with prior airway procedures, RTFS was significantly greater in the laser group, even after adjusting for age, smoking history, and stenosis etiology (50.0% vs\u00a016.8%,
