context_page_description: Breast augmentation and augmentation mammoplasty is a cosmetic surgery technique using breast-implants and fat-graft mammoplasty techniques to increase the size, change the shape, and alter the texture of the breasts of a woman. Augmentation mammoplasty is applied to correct congenital defects of the breasts and 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 creates a spherical augmentation of the breast hemisphere, using a breast implant filled with either saline solution or silicone gel; the fat-graft transfer approach augments the size and corrects contour defects of the breast hemisphere with grafts of the adipocyte fat tissue, drawn from the person's body.
  In a breast reconstruction procedure, a tissue expander is sometimes put in place and inflated with saline to prepare the recipient site to receive and accommodate the breast implant prosthesis.
context_section_description: There are four types of implant:
  Saline implants filled with sterile saline solution
  Silicone implants filled with viscous silicone gel
  Alternative-composition implants (no longer manufactured), filled with various fillers such as soy oil or polypropylene string
  "Structured" implants using nested elastomer silicone shells with saline between the shells.
