Breasts consist of milk ducts and glands that produce milk during pregnancy; enclosed in a thick layer of fatty tissue. The breasts overlie the muscles of the chest. Advancing age may cause the breasts to droop or sag. Loss of skin elasticity, gravity and other factors such as pregnancy and nursing can also cause the breasts to lose their natural shape and firmness.
Breast implants are artificial shells made of rubber filled with sterile saline or silicone gel which is surgically implanted below the breast tissue for cosmetic purposes to augment the shape and size of the breast or for breast reconstruction. Breast reconstruction may be performed after mastectomy or loss of breast tissue secondary to trauma or injury. In a few cases, it may also be performed to rectify a birth defect. Breast implants can be placed either under or over the chest muscles.
Breast implant can be considered in women with the following characteristics:
Choosing the right breast implants is based on the following characteristics of the implant:
Saline filled breast implants are safer in event of an implant rupture, only the filled saline is released into the tissue. The empty implant can then be removed or replaced. Moreover, saline filled implants are filled with saline only after surgical placement of the implant, thus they require a smaller incision for placement. Filling during the surgery also allows the surgeon to make minor adjustments to the volume. However, these implants look less natural as compared to silicone filled implants.
Silicone gel filled implants have a more natural look and feel firmer and softer than the saline implants. Silicone gel filled implants are pre-filled and require a longer incision for implantation. Only women over 22 years of age are eligible for breast augmentation using silicone filled breast implants.
Breast implants that are too large will eventually sag. … Breast implants that are too large or too firm can stretch and pull the skin holding them, and will inevitably cause the breasts to lose shape over time. If too much weight is placed on the tissues, gravity does its part, and can pull the implants down.
