Breast augmentation with fat transplantation (fat transfer) uses liposuction to harvest excess fat from other parts of the body; the fat is then injected into the breasts. This method of breast augmentation is appropriate for women who are not looking for a dramatic increase in breast size, and want breasts that look and feel as natural as possible.
For a number of weeks prior to augmentation mammaplasty, tissue expanders may be placed below the muscles of the chest wall to expand the breasts, and increase the amount of fat they can hold. When the tissue has expanded enough, augmentation using fat transfer can begin. First, fat is removed using liposuction, in which a cannula (a thin, hollow tube) is inserted through small incisions, and then moved back and forth to loosen excess fat, which is suctioned out using a vacuum or a cannula-attached syringe. The harvested fat cells are then purified. In the second procedure, which takes place on the same day, the fat is injected into the breast through small incisions. The procedure takes approximately 4 to 5 hours.
