The dorsal aspect of the hand is one of the areas of the body that show the most volume reduction due to fat loss. This phenomenon reflects an aging hand that frequently causes aesthetic concerns. Autologous fat grafting of this region is easy and highly successful. This procedure is performed through one or two puncture incisions that leave no residual scars. The grafted fat blends with other structures of the dorsal hand such as veins and tendons restoring its youthful appearance. As with fat transfer to the face and other areas, the overlying skin texture improves due to biologic activity of the transplanted cells.
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.
