The superior gluteal artery perforator (SGAP) flap and the inferior gluteal artery perforator (IGAP) flap are two possible alternatives to the DIEP flap if there is not enough tissue on the abdomen to use for breast reconstruction. The tissue used for these flaps comes from either the upper lateral buttock roll or from the lower lateral buttock roll. The beauty of these two flaps is that, again, muscle is not usually taken with the harvesting, and the resulting buttock scar usually heals extremely well and is often hidden within the underwear or bathing suit line.
