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 × 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. |
