[History and progress of trachea transplantation in Mexico].

Central airway obstruction and particularly tracheal stenosis is a clinical problem where definite resolution is a tracheal resection, evaluating the magnitude, length, and ventilatory compromise of patient. The resectable fragment is limited to 30% of the total length in children, or 6 cm in adults with terminal end anastomosis. The replacement of longer sections through allogeneic transplantation has been disappointing due to the unfeasibility of the organ, rejection of the graft, and the highly complicated surgical procedure. Tissue bioengineering has designed the replacement of functional organs generated in vitro in the short term, with the absence of immunological responses to the graft. This is based on a non-biological matrix where epithelial and mesenchymal cells are planted in such a matrix. In this document, we review the history and development of trachea transplantation in Mexico as well as the application of these new technologies in the context of its world development, which is a reality in other countries as a new alternative in obstructive illness of the airway.
