After extended excision of the cervical trachea, the airway is usually reconstructed by end to end anastomosis of the trachea or transplantation of the skin and other autologous grafts. However, these surgical methods do not always produce succsessful results in respect of surgical invasion, complications and postoperative QOL.<BR>Although reconstruction of the trachea using an artificial trachea is considered to be simple and easy, there is no suitable material for this purpose.<BR>We tried to reconstruct the airway with an artificial trachea made from collagen.<BR>As a result, the collagen graft was absorbed about 12 weeks after implantation and replaced by connective tissue with suitable rigidity. The inner wall of the reconstructed airway was lined by a ciliated columnar epithelium. We conclude that collagen products after cross-linkage with a suitable compound can be used for tracheal reconstruction.
