TUG, VUG, and DUG flaps all take a flap of tissue from the thigh. The main different is in the scar placement: a TUG flap will leave a scar going across the thigh, a VUG flap leaves a scar going down, and the DUG flap scar runs diagonally in the inner thigh. A gluteal-based flap takes skin and fat from the buttocks, and this can be an option for women who have excess tissue in these areas.
