title: Reconstruction of scalp defects using simple designed bilobed flap.
abstract: We have devised a novel rational method to design a bilobed flap. In our method, two triangle flaps are designed; the angle of the first flap is three-fourths the angle of a rhombus at the defect site, and the angle of the second flap is also three-fourths that of the first flap. We have successfully performed reconstruction of scalp defects as large as 50 x 45 mm using simple designed bilobed flaps. The location of the defect was the parietal region in 10 cases, the frontal region in 6 cases, the temporal region in 3 cases, and the occipital region in one case. The advantages of this method for use in reconstruction of scalp defects are as follows: (1) the dispersion tension on the flap provides stable circulation and prevents expansion of scar formation; (2) since the suture line is zigzag, alopecia at the suture line can be hidden under the hair; (3) since this flap is a random pattern flap using galea aponeurotica with blood flow to the skin, flap design is possible for any part of the scalp; and (4) design and elevation of this flap are easy and do not take much time.
