Twenty patients have undergone repair of laryngeal and tracheal stenosis by microtrapdoor accessing of scar or soft tissue and removal with the carbon dioxide laser. A total of 34 flap procedures were performed in the 20 patients. Follow-up ranged from 8 months to 4 years, and 30 of these flaps were considered successful on the basis of improvement of the airway. The only complications were postoperative granulation tissue in 2 patients that responded to endoscopic removal.
