Tracheal sleeve resection for iatrogenic stenoses (subglottic laryngeal and tracheal).

Since 1975 200 tracheal sleeve resections for iatrogenic tracheal and subglottic laryngeal stenoses have been performed in our institution. Preoperative Nd:YAG laser is of paramount help in opening the stenoses. Tracheography is usually performed to specify the length of the stenosis and the distance from the vocal cords. Operative procedures are described. One hundred seventy five (87.5%) patients are definitely cured, but in this group 16 patients required a Montgomery tube for 6 months to 1 year to recover a normal tracheal diameter. Two patients needed a second tracheal sleeve resection. Nine (4.5%) patients died, and 16 (8%) had recurrent stenoses. Stenoses in these patients were treated with use of a tracheostomy tube, a permanent Montgomery tube, or an endotracheal stent. Partial anterior cricoid resections performed in 21 patients have had the same results as those of the whole series. Twenty one laryngeal releases were performed and proved to be efficient and safe. In our experience complications can be avoided by good selection and preparation of the patients, accurate identification of the level and length of the stenosis, and meticulous technique.
