Popis: | To make experimentally the bridge part byautograft-transplantation, adult rabbits were usedin the following fashion, and postoperative coursewas pursued histologically. The auricular cartilagewas exposed in a circular form (22mm. indiameter), and a hole (6mm. in diameter) wasopened at the center of the exposed part. The skingraft prepared from ear lobe (0.3-0.4mm. or 0.5-0.6mm. thick) was transplanted over the hole andprotected with a plastic chamber.The results were as-follows;(1) The granulation grew under the bridgepart of the skin graft, and the regenerated epidermiscovered it in two weeks.(2) At the bridge part, the perforation wasfound in about 58% of the cases of free grafts, but with the pedicle flap it was only in 6%, provingmore profitable than the free graft.(3) With a pedicle flap and a thin free graft, its epidermis exfoliated, but with a thick freegraft, the epidermis and the upper layer of itscorium became necrotic and was shed off. Then aregenerated epidermis covered the exfoliated regionof the graft (one-two weeks). Their grafts becamethicker about two times by the granulation growingunder the skin graft.The above findings were observed both in thebridge part and in the cartilagenous part aroundthe bridge hole.(4) The blood circulation observed by injectingindian-ink into the artery in the whole part ofthe free graft was recognized in the seventh day, but in the pedicle flap it was earlier than in thefree graft.(5) In transplanting a tatooed graft, it wasconfirmed that the transplanted tissue itself wastaken on the recipient bed. |
