Autologous tracheal replacement for cancer

Area of Science:

• Surgical innovation
• Plastic surgery
• Regenerative medicine

Background:

• Fifty years of surgical research has not yielded an ideal tracheal substitute after resection.
• Existing prostheses pose risks of erosion, infection, and obstruction.
• Novel plastic surgery techniques offer improved solutions for tracheal reconstruction.

Purpose of the Study:

• To describe a novel technique for tracheal replacement using autologous free fasciocutaneous flaps.
• To evaluate the efficacy and outcomes of this technique in patients requiring tracheal reconstruction.
• To detail the surgical indications, methods, and postoperative management for this procedure.

Main Methods:

• Utilized forearm free flaps (FFF) for constructing tracheal replacement tubes.
• Reinforced flaps with autologous rib cartilage for structural integrity against respiratory pressure.
• Performed completely autologous reconstruction without internal stents in the tracheal lumen.

Main Results:

• Successfully reconstructed the trachea in 16 patients between 2004 and 2015.
• Treated primary tracheal neoplasms (adenoid cystic carcinoma, squamous cell carcinoma), secondary neoplasms, and benign lesions.
• Demonstrated a viable, stent-free, autologous solution for tracheal defects.

Conclusions:

• The described technique using forearm free flaps and cartilage offers a promising, completely autologous method for tracheal reconstruction.
• This approach effectively addresses limitations of synthetic prostheses, reducing risks of complications.
• The study highlights the potential of plastic surgery innovations in complex airway reconstruction.
