Breast augmentation and augmentation mammoplasty (colloquially known as a "boob job")
are plastic surgery terms for the breast-implant and the fat-graft mammoplastyapproaches used to
increase the size, change the shape, and alter the texture of the breasts of a woman. As a primary
reconstruction, augmentation mammoplasty is applied to effect a post–mastectomy breast
reconstruction, the repair of the chest wound consequent to the removal of a cancerous breast; to
correct congenital defects of the breast(s); and to correct congenital defects of the chest wall. As an
elective, cosmetic surgery, primary augmentation changes the aesthetics — of size, shape, and
texture — of healthy breasts.
The surgical implantation approach effects the global augmentation of the breast hemisphere using
a breast implant, either an implant filled with saline-solution, or an implant filled with silicone-gel;
moreover, the surgical augmentation approach can include the application of transplanted
autologous skin flaps harvested from the woman’s body. The fat-graft transfer approach augments
the size and corrects contour defects of the breast hemisphere with grafts of autologous adipocyte
fat tissue, drawn from the woman’s body.
