Objective To investigate a new method for preparing donor graft in order to shorten the width of the donor area and suture the donor defect directly. Methods The size of the donor graft was determined as the product of the width and length of the donor area multiplied by factors of 0.6 and 1.5, respectively. Results By this means, the width of donor graft was significantly reduced, the donor defect could be sutured directly, and the size of the defect was diminished by 1/3. So, the operation strategy was simplified and waste of donor skin was also avoided. Conclusion Application of skin graft in size equal to the defect may be a practical method for repair of fairly large skin defect.
