Benign tracheal and laryngotracheal stenosis: surgical treatment and results.
OBJECTIVE
Benign tracheal stenoses remain the most common indications for tracheal resection. We report lessons learned with surgical management of tracheal stenoses in a consecutive series of 65 patients from the beginning of our experience to date.


METHODS
From December 1991 to January 2001 65 patients underwent primary tracheal and laryngotracheal resection and reconstruction for non-neoplastic stenoses. There were 39 males and 26 females with a median age of 33 years (range 14-74 years). There were 58 cases of postintubation and seven of idiopathic stenosis. A cervical approach was used in 60 patients, and a cervical incision with sternal split in four and with sternotomy in one. We performed 45 (69.2%) tracheal resections and 20 (30.8%) laryngotracheal resections. The length of resection ranged between 1.5 and 4 cm (median 2.5 cm). The range of resected rings was two to eight (median five).


RESULTS
Fifty-four patients received a preoperative treatment. Preoperative procedures consisted of laser therapy (37), tracheostomy (38) and endotracheal prosthesis (16). We had major complications in eight patients (12.3%) and minor complications in 15 patients (23%). The most frequent complications were: temporary vocal cord dysfunction (eight patients), wound infection (five patients), anastomotic dehiscence (four patients), vocal cord paralysis (two patients), granulation tissue (two patients), deglutition dysfunction (one patient) and restenosis (one patient). Perioperative mortality was 1.5% (one patient). In classifying final results obtained, 54 patients achieved an excellent result, eight a good result and two satisfactory.


CONCLUSIONS
The strategy for treatment of airway stenoses is now well established and leads to a high level of success with minimal or no sequelae. Meticulous preoperative assessment and preparation associated with a perfect surgical technique is mandatory to obtain good results. Preoperative treatments (laser and/or endotracheal prosthesis) could increase the extent of injury and the length of stenosis.
