Body fat makes excellent soft tissue filler material. It can be used to recontour the face; diminish frown lines, crow's feet and nasolabial folds (smile lines); and provide definition to areas like the cheeks and chin. It can also be used to fill out depressed scarred areas on any part of the body. Fat injection is not permanent, and may require an effective maintenance program.
The procedure
After both the donor and recipient sites are cleansed and treated with a local anesthesia, the fat is withdrawn using a syringe with a large-bore needle or a cannula (the same instrument used in liposuction) attached to a suction device. The fat is then prepared and injected into the recipient site with a needle. Sometimes an adhesive bandage is applied over the injection site.
It is necessary to "overfill" to allow for fat absorption in the weeks following treatment. When fat is used to fill sunken cheeks or to correct areas on the face other than lines, this overcorrection of newly injected fat may temporarily make the face appear abnormally puffed out or swollen.
After treatment
If a larger area was treated, you may be advised to curtail your activity for a brief time. However, many patients are able to resume normal activity immediately. You can expect some swelling, bruising or redness in both the donor and recipient sites. The severity of these symptoms depends upon the size and location of the treated area. You should stay out of the sun until the redness and bruising subsides-usually about 48 hours. In the meantime, you may use makeup with sunblock protection to help conceal your condition.
The swelling and puffiness in the recipient site may last several weeks, especially if a large area was filled.
Results
The duration of the fat injections varies significantly from patient to patient. Though some patients have reported results lasting a year or more. Your doctor will advise you on how to maintain your results with repeat treatments.
Your new look
If you're like most patients, you'll be very satisfied with the results of your injectable treatments. You may be surprised at the pleasing results that can be gained from this procedure.
