The authors have devised a novel method of designing a flap for coverage of posttraumatic temporal hairline alopecia. They have successfully performed restoration of temporal hairline alopecia as large as 18 x 4 cm resulting from a previous trauma treated with a primary grafting. The new method uses a simple flap designed preoperatively by Doppler based on the supraorbital vessels up to the flap's anastomosis with the occipital vessels. This flap is easy to design and elevate with sufficient blood flow. Alopecia resulting from scar formation at the suture line is not conspicuous. The donor site can be closed primarily, and no dog ear has resulted from its application.
