The objectives of the augmentation prostheses are to increase the volume, enhance the shape, and improve the projection of the breast. Since 1962, plastic surgeons have used the silicone gel-filled breast implant created by Cronin and Gerow [6]. The contents of the standard implant have been modified: silicone gel-filled, PVP, dextran, oil, saline hydrogel, etc. The shell of the prostheses had been made with a smooth surface, textured silicone, and polyurethane-covered silicone. The shape has been modified: In 1993, A. Miller patented the stacked breast implant used in breast reconstruction [7]. This contribution tends to improve the projection of the breast. In 1994, the authors [1,3,4] described a new surgical procedure for locating the standard implants named the double pocket technique. Simultaneously, the authors [2–5] modified the shape of the prosthesis creating the double implant prostheses.
