Abstract:
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.

Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of...
Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

Tracheostomy Decannulation
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
