SCULPTING THE TUG FLAP
The crescent shape of the TUG flap allows it to be shaped by coning, giving it projection, and a rounder appearance. The projection is superior to that created by DIEP and SIEA flaps, and gives a more natural contour to the new breast. By using the crescent shape and folding to full advantage, the nipple areola structure can be created. The natural darker color of the inner thigh compared to the relatively pale breast color, give the areola superior shading of skin than can be obtained with tattooing.
The tissue that is taken from the inner thigh is folded. The lateral image (figure C.) illustrates TUG projection, because of the coning that takes place with folding. When the flap is further refined, the nipple and areola are made from the skin paddle, and key tacking sutures.
