Benign stenosis of the trachea.

Benign stenosis of trachea results mainly from tracheotomy, ventilation, or trauma. The combination of a defect of the mucosa or the tracheal wall and infection produce secondary scar tissue healing with shrinkage of the tracheal lumen or instability of the tracheal wall. Standard of treatment consists of resection of the pathologic segment of the trachea with end-to-end anastomosis. In case of involvement of the larynx, partial resections of the anterior cricoid cartilage or division of the larynx with tracheolaryngeal silicone stents are used. Short-term and long-term results are satisfying considering some technical recommendations.
