ABSTRACT
In most cases of sheet skin grafting, epithelialization is finally completed even if small necrotic skin areas occur. In such cases, the cosmetic appearance of the skin is not optimal because of unsightly scar formation accompanying the reepithelialization during wound healing in necrotic areas. However, when cosmetic improvement is the purpose in skin grafting on the face or hands, almost complete survival is demanded. Even a tiny hematoma the size of a grain of rice can cause a small amount of necrosis. Pressure irregularities routinely occur in conventional pressure dressing, with hematomas occurring in the weak locus of pressure inducing partial necroses. To solve this problem, we have devised a new pressure method (1,2) for skin grafting to produce the least amount of hematoma possible. Transparent and adhesive drapes and a disposable suction drain are used in this method, which we refer to as the suction-drain method. This method contributes not only to maximal graft survival due to uniform and constant pressure but also to overall excellent cosmetic results.
