Two new free flaps developed from aesthetic surgery II. The inferior gluteal flap.

A new vascular musculocutaneous flap from the lower buttock is described that is based on the inferior gluteal vessels and includes skin from the gluteal fold and a part of the gluteus maximus muscle. The inferior gluteal flap has been clinically used either as an island flap for sacral repair or as a free flap. The results of 6 clinical cases are presented and the features of the flap are exposed. The minimum residual deformity of the buttock contour and, even in some cases of trochanteric lipodystrophy, the cosmetic improvement of the donor site appearance are emphasized.
