Figure 2: (a)-(b) The defect site and muscle flap design after elevating the fasciocutaneous flap. From the inferior margin of the fasciocutaneous flap to the inferior region of the buttock, 10–15 cm was dissected to sufficiently reveal the inferior portion of the gluteus maximus. (c) Then, a U-shaped muscle flap that was 80% to 90% of the defect size was elevated. (d) Clinical photograph at 5 months postoperatively.
