Breast augmentation can also be performed by transferring fat cells into the breasts from other areas of the body. The fat cells are harvested using various forms of liposuction, then separated and concentrated from surrounding fluids. After processing, the fat cells are injected into the breast tissue. This is meticulously done in a layered fashion in order to maximize the viability of the transferred fat.
This fat transfer procedure is usually preempted with external breast expansion for approximately 30 days. This is accomplished with a BRAVA negative pressure vacuum device that expands the breast and improves breast blood flow to maximize the survival or “take” of the transferred fat cells.
Fat transfer breast augmentation is a relatively new procedure. Currently, it is most commonly used as a tool to improve results of breast reconstruction after breast cancer surgery or to improve breast implant-related issues such as visible “rippling.”
Ongoing research is being conducted to establish the safety and efficacy of this procedure for primary cosmetic breast augmentation. Given the current technology, fat grafting only offers limited volume enhancement when compared to breast implants.
