Abstract
We reconstruct the dog trachea with the composite of collagen and Marlex high density mesh. The supporting consistency of this mesh is sufficient enough to prevent air way collapse. Since the regeneration of the epithelium progresses from the cut ends, long replacement may be more easy than the wide one. Physiological function of the reconstructed trachea was examined by means of cine-bronchogram and endoscopic observation of the expectoration of India ink. Even on the six months after operation, both the tracheal contractility and mucociliary transport were impeded to some extent, but in clinically, which seemed to be out of hindrance.
