Abstract
A surgical technique of laryngotracheoplasty with long-term stenting was employed exclusively in the treatment of 105 patients with laryngotracheal stenosis in the Department of Otolaryngology, National Taiwan University Hospital from May 1977 to April 1989. The results were satisfactory, 92% of the treated patients being decannulated. The technique of laryngotracheoplasty can be summarized as follows: (1) Exposure of the stenotic region by laryngofissure, anterior and/or posterior cricoid splitting, vertical tracheal incision; (2) debridement of infected soft tissue; (3) relaxation or displacement of heavy scar tissue; (4) placement of sutures to tent the laryngotracheal mucosal remnants to the extraluminal region; (5) insertion of a endolaryngotracheal stent using a silicone T tube; (6) closure of the skin layer of the surgical wound only, without approximating the soft tissue layer between the T tube and skin; and (7) leaving the stent in place for at least 6 months.
