Anterior Mediastinal Tracheostomy: Past, Present, and Future.

Anterior mediastinal tracheostomy (AMT) is established after division of the retrosternal trachea following resection of extended upper airway malignancies, stomal recurrences, or cervicomediastinal exenteration. AMT is occasionally performed for nonmalignant diseases. Starting in the 1980s, the use of a pectoralis major myocutaneous island flap reduced the mortality attributable to innominate artery rupture previously reported in historical series. Recent advances in the vascular reconstruction of supra-aortic trunks could allow future development of AMT as salvage surgery. On the other hand, construction of the stoma using free flap procedures and advances in chemoradiotherapy could simultaneously reduce the indication for AMT.
