Laryngeal and tracheal stenosis have been refractory to a variety of treatment including dilation, stents or have required major open operation, e.g. laryngofissure with or without skin or mucosal graft and segmental resection with larynx release. The authors have experienced 39 cases of laryngeal and tracheal stenosis. 21 cases were due to tracheostomy and endotracheal intubation. Site of stenosis was divided into glottis, subglottis and trachea. Stenosis of more than one anatomical region was classified as multiple site stenosis. The authors tried various treatment modalities, e.g. endoscopic dilation, intralesional steroid injection, stent insertion, arytenoidectomy, hyoid transposition, auricular cartilage graft and segmental resection-anastomosis. The authors considered decannulation without recurrent dyspnea as success. Success rate of single site stenosis was 80%, and that of multiple site was 33.3%. The authors reviewed the treatment modalities for the specific site and extent of the lesion.
