A group of 89 patients suffering from tracheostenosis was studied in the period from January 1990 to January 1999. Surgical procedure on trachea was performed in 63 patients with postintubation (posttracheostomic) stenosis, in 6 patients with direct tracheal trauma, in 9 with tracheoesophageal fistula, in 7 with malignant stenosis, in 3 with postinflammatory subglottic stenosis. In the treatment of tracheal stenosis a set of methods was used ranging from laser and tracheal endoproteses, through cartilage implantation and plastic reconstruction of tracheal defects to extensive segmental resections. In a group of 50 patients with segmental resection in 43 (%) of them the result was good, in 2 (4%) of them satisfying, in 4 (8%) of them temporary brace (on T-cannule) persists, 1 patient died in postoperative period (2%). In a group of 39 patients with combined conservative treatment in 18 patients good results were reached (43.8%), in 6 satisfying (15.4%), in 13 of them temporary brace (on T-cannule) persists (33.3%) and 2 died in postoperative period (5.1%). In conclusion the results of this work suggest that the most frequent indication for surgical treatment is postintubation (postracheostomy) stenosis and that segmental trachea resection has priority in the treatment of tracheal stenoses.
