the third technological development was the double lumen breast implant device, a double-cavity prosthesis composed of a silicone breast implant contained within a saline breast implant. The two-fold, technical goal was: (i) the cosmetic benefits of silicone-gel (the inner lumen) enclosed in saline solution (the outer lumen); (ii) a breast implant device the volume of which is post-operatively adjustable. Nevertheless, the more complex design of the double-lumen breast implant suffered a device-failure rate greater than that of single-lumen breast implants. The contemporary versions of second-generation breast implant devices (presented in 1984) are the "Becker Expandable" models of breast implant, which are primarily used for breast reconstruction.
Larger areas of the body like the breasts and butt end up being two separate procedures—a full liposuction and a full fat injection—and as such, will typically end up costing more. According to RealSelf.com, the national average cost of a breast fat transfer is $6,525, while the national average cost of a buttock fat transfer is $8,625. The average cost of a traditional implant breast augmentation is $6,300, according to RealSelf.com.
Another option is to consider getting your breast implants at a teaching hospital from a learning resident. You won’t get the delicate skill of an experienced, board-certified surgeon, but teaching hospital residents are “assisted by established, experienced, private attending surgeons,” says Beverly Hills plastic surgeon Dr. Robin T.W. Yuan in a RealSelf Q&A.
