Aesthetic breast augmentation: the double implant

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. 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. This contribution tends to improve the projection of the breast. In 1994, the authors described a new surgical procedure for locating the standard implants named the double pocket technique. Simultaneously, the authors modified the shape of the prosthesis creating the double implant prostheses.
