WIDE excision of the cervical trachea may be necessary in the treatment of certain lesions. The most common of these are: primary tracheal neoplasms, extrinsic malignancies invading the trachea, and tracheal stenosis secondary to trauma or infection.1
The ideal method of repair is by end-to-end anastomosis, and defects up to 4 cm may be closed this way. Tension develops with larger defects and breakdown of the suture line usually occurs. Cantrell and Folse2 found in animal experiments that when the tension on tracheal suture lines was less than 1,700 gm, primary union could be expected. If the tension was 1,700 to 2,200 gm, the results were unpredictable, and a tension exceeding 2,200 gm rarely resulted in healing.
The most logical attack on large defects is to bridge them with a tracheal graft. Many materials have been tried experimentally. Fresh and lyophilized homografts, polyethylene, Teflon, glass, polyurethane, and silicone-rubber
