Fat or adipose tissue harvested from sculpted areas of the body can be preserved safely and re-injected in the face in order to re-create its most natural aesthetic shape and restore a youthful appearance. Autologous fat transfer is a common technique used to rejuvenate the face. Furthermore, it has been found that the skin overlying the area of the transfer improves its texture and appearance due to the biologic activity of the new cells. In other words, transferred fat not only provides volume and structure to the recipient site, but also greatly contributes with nutrition and mediators that further enhance the appearance of the overlying skin.
Fat transfer is done using a local anesthetic and mild sedation. A small surgical instrument known as a cannula is inserted into the area of fat removal. The cannula is attached to a vacuum source, which provides gentle suction to remove the emulsified fat. Modern techniques of liposuction target fat cells leaving behind a normal collagen matrix. Medilaser, Cosmetic Surgery and Vein Center
introduced Body-Jet® Liposuction. This amazing technique uses pressurized water or water jet to obtain fat tissue sparing not only that remaining matrix but also the integrity of the graft adipose and stem cells. This concept renders enough cell survival that there is no need to enhance the graft with PRP (platelet rich plasma) or stem cell isolation and enrichment. As with other techniques such as vibroliposuction, fat is emulsified while simultaneously extracted. After being processed through a LipoCollector® 3 device, this fat is then ready to be grafted or transplanted.
Fat transfer is not new; it has been performed for decades. However, its results were suboptimal due to the poor graft survival in the past. This has changed considerably with the advent of modern liposuction techniques. Water assisted liposuction, ultrasound liposuction, power assisted liposuction and vibroliposuction are the most recently developed techniques responsible for the current success of fat transfer today. Medilaser surgeons, Drs. Robinson and Giraldo, were the first in the United States in performing liposuction using vibrating cannulas. They taught surgeons from different parts of the country this new minimal invasive technique. Today, many patients have successful procedures with long lasting transplants that give them younger looks. In an evidence based review article published in the Journal of Plastic and Reconstructive Surgery, water assisted liposuction and power assisted cannulas were found to be the best liposuction techniques available today. This translates to exceptional and consistent harvesting procedures for fat transfer.
