Subglottic tracheal resection and synchronous laryngeal reconstruction

Area of Science:

• Otolaryngology and Thoracic Surgery
• Airway Reconstruction
• Laryngotracheal Stenosis Management

Background:

• Postintubation injury frequently causes upper airway stenosis affecting the larynx, subglottis, and trachea.
• Traditional surgical correction involves staged procedures with variable and unpredictable outcomes.
• Permanent extubation remains challenging for many patients with combined laryngotracheal stenosis.

Purpose of the Study:

• To evaluate a one-stage surgical technique for combined laryngeal, subglottic, and tracheal stenosis.
• To assess the efficacy of circumferential resection and thyrotracheal anastomosis combined with laryngofissure.
• To compare outcomes with traditional staged reconstruction methods.

Main Methods:

• A cohort of 15 patients with combined laryngotracheal stenosis underwent a one-stage operation.
• The procedure included circumferential resection of the subglottis and trachea with primary thyrotracheal anastomosis.
• Concomitant laryngofissure with laryngeal reconstruction (scar excision, mucosal grafting, joint mobilization) was performed, followed by temporary stenting.

Main Results:

• The thoracic surgical division performed 53 such resections between 1972-1991 with no operative deaths.
• 51 of 53 patients were successfully extubated; 13 of the 15 patients in this specific cohort are now permanently extubated.
• No functionally significant restenosis was observed, and vocal function was satisfactory to good in the treated patients.

Conclusions:

• The described one-stage surgical approach for combined laryngotracheal stenosis yields superior results compared to traditional staged techniques.
• This collaborative surgical strategy enhances successful extubation rates and functional recovery.
• Multidisciplinary collaboration between Otolaryngology and Thoracic Surgery is crucial for optimal patient outcomes.
