The concept of perforator flap started in the late 1980s, and it refers to a flap that is supplied by only a small (0.5 mm outside diameter) skin perforator vessel, which belongs to the category of axial vascular flaps. It can be made according to the need of the type of defective tissue in the recipient area, which is in accordance with the principle of “what is missing is what is needed” for reconstruction. The most prominent feature of the perforator flap is that it is thinner than the flap cut by traditional methods, minimally invasive, with concealed scar and rapid postoperative recovery. Currently, it is a popular repair tool in the field of flap surgery. For this reason, the department sent Dr. Zhang Daming, an attending surgeon, for a special training course and successfully carried out this technique after returning to the department.
