Anterior Mediastinal Tracheostomy: Past, Present, and Future

Area of Science:

• Thoracic surgery
• Surgical oncology
• Head and neck surgery

Background:

• Anterior mediastinal tracheostomy (AMT) is a reconstructive procedure following extensive upper airway resections for malignancy or nonmalignant conditions.
• Historically, AMT carried significant risks, notably innominate artery rupture.

Observation:

• The introduction of pectoralis major myocutaneous island flaps in the 1980s significantly decreased mortality associated with innominate artery rupture.
• Current advancements in vascular reconstruction techniques for supra-aortic vessels present new possibilities for utilizing AMT in salvage scenarios.

Findings:

• While advances in free flap construction for stoma creation and improvements in chemoradiotherapy may decrease the overall indication for AMT.
• These developments also highlight the potential for AMT to serve as a salvage procedure in complex cases.

Implications:

• Future research should focus on refining free flap techniques and optimizing chemoradiotherapy protocols to balance the reduced need for AMT with its potential role in salvage surgery.
• The evolving landscape of airway reconstruction necessitates a re-evaluation of the indications and techniques for anterior mediastinal tracheostomy.
