a) 45% of The autografts were successfully transplanted, and the dogs were survived for a long time.
b) Three kinds of the suture-material were used in the transplantation. The survival rate was 54% in the cases with stainless steel wire, 46% in the cases with nylon suture, and 36% in the cases with silk suture.
c) The suture causing granuloma was more frequently found in the stainless steel suture group than the other 2 groups. The reason of occurernce of the granuloma was discussed.
2) The defect of the trachea was repaired with metal mesh and isolated fascia.
a) All window defects, with more than 180 dergree loss of substance, were repaired successfully, but the segmental defects were completely failed to be reconstructed.
b) The failure of repairing the segmental defect was seemed to be due to the complete interruption of mucosal lining at the site of the reconstruction.
c) A unit of stainless steel mesh, free fascia and the mucosal bridge reconstructed on the gap was used to repair the segmental defect, but the result was not satisfactory. The mucosal bridge was not found frequently at autopsy.
d) The trachea with window defect, as an ideal form of the mucosal bridge, was enveloped with metal mesh and fascia, but only 1 of 5 cases survived for a long time.
e) The window defects were successfully repaired with flap of the metal mesh and isolated fascia, but unsuccessfully by wrapping with the envelope-shaped mesh and fascia, and the poor blood supply seemed to b the main cause of the failure of the segmental recostruction.
