Abstract
By means of the histological and histochemical methods, we studied the puncturing skin graft in animal and experiments.The results are as follows:1. The punctured full thickness skin grafts are supplied from the host to the epidermis through the punctured canal and the crevice of tissue within several hours, therefore there is hardly danger of necrosis.2. Generally, a grafted skin is supplied nutrient gradually around the skin flap, through the crevice of tissue. Therefore, there is danger of necrosis if skin grafts were very thick and large.Clinical experience:1. We have experienced on 11 patients (22 locals.) who are suffered from contraction of scar tissue by puncturing full thickness skin graft, and the performances were all led to success. (largest 140cm2.: success)2. Operative technique. I transplanted full thickness skin to the wound after removing of scar tissue, with general attention, and then punctured the grafting skin by the injection's needle. (30 Punctures, per 10cm2.) The bandage and fixation were tried with general attention.
