Forty‐six dogs had a five ring segment of their trachea resected and replaced with different prostheses. The different prosthetic combinations are described, and a technique of sutureless anastomosis which eliminated intra‐luminar sutures is reported. The initial prosthetic combinations were developed to provide support for regeneration of the animal's own mucosa. In no cases was there any evidence of migration of mucosa into the prosthetic segment. The animals were sacrificed if they developed any signs of airway impairment or respiratory distress. All post mortem tracheas were examined and photographed. The best results were obtained when the prostheses had a smooth, nonporous artificial lining which was either thin walled stainless steel or shrinkable teflon tubing. Even though this experiment failed to produce a successful long‐term prosthetic tracheal replacement, encouraging results indicate that further experimentation would be worthwhile.
