We analyzed 26 cases of tracheal stenosis treated (ET) surgically at the National Institute of Respiratory Diseases between March 1987 and June 1990. The surgical technique practiced was end-to-end anastomosis of the trachea (ATT). The most important cause of stenosis was oro-tracheal intubation (69.2 percent). Followed by tracheostomy, respiratory scleroma, thyroid carcinoma with tracheal invasion and neck trauma. We describe the treatment of the patients and discussed the results, which were satisfactory from the functional anatomical point of view in all patients except one who died of hepatic coma 2 weeks postoperatively. We conclude that end-to-end anastomosis of the trachea is the treatment of choice to tracheal stenosis.
