Objective To study the research advance in tracheal allografts undergoing revascularization and reepithelialization. Methods Therecent literature concerned was reviewed. The tracheal allografts are embedded in the omentum, which they were revascularized and reepithelialized by planting in self-epithelia, then the allografts with their omental pedicles were transplanted orthotopically to the cervical or the thoracic portion of the trachea. Results Compared withthe onestage tracheal allograft approach using the greater omentum, the twostage approach could increase the successful rate of revascularization and reepithelialization, and made the allografts accord with their physiology. Conclusion If the approach is successful, it can reduce graft-rejection, prevent graft-collapse and increase graft-viability after tracheal allograft.
