Benign stenosis of the trachea

Area of Science:

• Pulmonology
• Otorhinolaryngology
• Surgical Pathology

Background:

• Benign tracheal stenosis commonly arises from tracheotomy, mechanical ventilation, or trauma.
• Mucosal defects or tracheal wall damage, coupled with infection, lead to scar formation, causing tracheal lumen shrinkage or wall instability.
• Existing treatments focus on surgical repair of the compromised tracheal segment.

Purpose of the Study:

• To review the causes and standard treatment for benign tracheal stenosis.
• To evaluate the efficacy of surgical resection and anastomosis for tracheal defects.
• To discuss laryngeal involvement management and overall treatment outcomes.

Main Methods:

• Review of literature on benign tracheal stenosis etiology and management.
• Analysis of surgical techniques including tracheal resection with end-to-end anastomosis.
• Description of procedures for laryngeal involvement, such as anterior cricoid cartilage resection or tracheolaryngeal stenting.

Main Results:

• Tracheal resection with end-to-end anastomosis is the standard treatment for tracheal stenosis.
• For laryngeal involvement, partial anterior cricoid cartilage resection or silicone stent use is described.
• Satisfactory short-term and long-term results are achievable with adherence to technical recommendations.

Conclusions:

• Benign tracheal stenosis management primarily involves surgical resection and reconstruction.
• Laryngeal involvement requires specialized surgical approaches to preserve function.
• Adherence to established surgical techniques is crucial for successful patient outcomes.
