A breast enlargement surgery / “boobjob” is a commonly performed cosmetic surgery in which silicone gel implants (I use Motiva) are placed behind / under the breast in order to enlarge the breast size.
Breast lift is an aesthetic surgery for those patients whose breasts have sagged as a result of weight loss, pregnancies and breastfeeding. The lifted breast can be made bigger (using implants) or smaller, as in a breast reduction, or be kept more or less the same size using an auto-augmentation procedure.
This surgery is designed to reduce an overly large breast, by removing skin and breast tissue and then constructing a more aesthetic, lifted and smaller breast mound.
Fat grafting has wide application in plastic and aesthetic surgery. Fat is harvested from sites on the body and then processed and re-injected using small blunt needle like devices called cannulae to place the fat. In breast surgery, it can be used as an adjunct to augmentation, lift or reduction procedures.
