Facial augmentation with structural fat grafting.

Fat grafting through a blunt cannula has been used by plastic surgeons for altering facial contours for 100 years. Autologous tissue is completely biocompatible and is usually the safest choice for altering facial volume or contours. Fat grafts can be placed in such a fashion that they are long lasting, completely integrated, and natural appearing. Only in the past 20 years have advances in techniques and instrumentation allowed us to obtain predictable results that make fat grafting a viable option for soft tissue augmentation. Our understanding of aging and methods of rejuvenation have developed also. We now approach rejuvenation and adjustment of facial proportion with a better understanding of the need for the restoration or adjustment of facial volume.

Structural fat grafting: more than a permanent filler.

Grafted fat has many attributes of an ideal filler, but the results, like those of any procedure, are technique dependent. Fat grafting remains shrouded in the stigma of variable results experienced by most plastic surgeons when they first graft fat. However, many who originally reported failure eventually report success after altering their methods of harvesting, refinement, and placement. Many surgeons have refined their techniques to obtain long-term survival and volume replacement with grafted fat. They have observed that transplanted fat not only adjusts facial and body proportion but also improves surrounding tissues into which the fat is placed. They have noted not only the improvement in the quality of aging skin and scars but also a remarkable improvement in conditions such as radiation damage, chronic ulceration, breast capsular contracture, and damaged vocal cords. The mechanism of fat graft survival is not clear, and the role of adipose-derived stem cells and preadipocytes in fat survival remains to be determined. Early research has indicated the possible involvement of more undifferentiated cells in some of the observed effects of fat grafting on surrounding tissues. Of particular interest is the research that has pointed to the use of stem cells to repair and even to become bone, cartilage, muscle, blood vessels, nerves, and skin. Further studies are essential to understand grafted fat tissue.

Hand rejuvenation with structural fat grafting.

A simple, reliable technique of autologous fat grafting for long-lasting rejuvenation of the dorsum of the hand is presented. With this technique, small intact parcels of fatty tissue are harvested with a syringe and a blunt 3-mm cannula. Then, most of the nonviable components are removed from the harvested subcutaneous material by centrifugation, decanting, and wicking. Finally, a 17-gauge blunt cannula places the fat in minuscule parcels of tissue with many passes through five or six tiny incisions in the hand. Separation of the tiny parcels of fat maximizes contact between the surfaces of the transplanted fat and surrounding recipient tissues to encourage integration, anchoring, and long-term survival. Structured, purposeful placement of a thin layer of transplanted fat rejuvenates the dorsal hand by restoring a slight fullness to atrophic subcutaneous tissue, by softening the color and definition of exposed extensor tendons and dorsal hand veins, and by supporting the aging skin.
