The easiest and most widely used method of Asian forehead augmentation employs injection of liposuctioned fat obtained from the patient's own body.
Since there is no surgical incision on the forehead, recovery is fairly rapid and there is no scar. The fat is most commonly obtained from the patient's thighs or abdomen, but almost any site can be used.
Once in a syringe, the fat is injected through a fine cannula passed many times through the tissues at different levels. The procedure takes thirty to sixty minutes. The forehead may be bandaged for about five days afterwards to control swelling.
The goal is to build volume to areas of generalized or discrete depression and create a less sloping contour on the highest third of the forehead.
Unfortunately, nearly half (if not most) of the transferred fat will die and absorb over the first six months, so more than one or two treatments may be needed to achieve and maintain the best result. As with all fat grafting operations, fat survival is highly technique-dependent.
The final forehead contour is usually smoother with a customized silicone implant than with fat grafting, which, because of irregular survival and loss, may appear somewhat irregular.
Any improvement is more apparent in side profile view that when viewing the face straight ahead.
