**5.3 Gluteal artery perforator flap**

It consists of two flaps named superior gluteal artery perforator flap and inferior gluteal artery perforator flap. The SGAP flap or superior artery perforator flap is based on perforators of the superior gluteal artery which is a branch of the internal iliac artery, the flap was originally described in 1993 and has been a good option for breast reconstruction due to minimum donor site morbidities.

The same group described the inferior gluteal artery perforator flap in 2004. Based on perforators of the inferior gluteal artery, a branch of the anterior division of the internal iliac artery that supply that supplies the skin in the lower part of the gluteal region or inferior gluteal crease [8]. However, the inferior gluteal artery perforator flap is less preferred because of an obvious scar over which the patient sits and the risk of injury to the sciatic nerve.
