Fat Transfer is also known as fat grafting or fat injection. This procedure transfers fat from areas in which you have excess fat, such as the outer thighs, and injects it into areas that may be lacking in volume, such as your face, breasts ,hands or buttocks.
The fat under the skin gives volume, shape and smoothness to our body. With ageing the volume of fat decreases and especially the face, neck and and hands lose the suppleness. Fat is one of the best soft tissue filler material. Fat can be taken from one part of the body (most commonly - thighs, waist and stomach) and injected into another. It can be used to reduce frown lines on forehead or to fill in other sagging parts of face or hands. Fat is harvested or removed from the donor site with a cannula under local or general anaesthesia. Excess fluid is removed from the fat and is reinjected with very fine cannula as multiple small injections into the treatment area. The micro-injections ensure a smooth distribution of fat and that the fat attains a blood supply and remains viable.The latest advances enable us to inject nanofat for finer wrinkles.
The advantage of using fat as filler is that it is natural, as harvested form your own body and is less likely to cause allergic reactions. It can be combined with liposuction with the benefit of two procedures in one sitting.
There maybe some bruising, tenderness or numbness in the donor and grafted area but it subsides within a couple of weeks. There is a small risk of infection and bleeding. Over or under correction of the defect can occasionally happen and the distribution of fat may not be smooth.
Facial fat transfer: If you have facial creases, such as laugh lines, smile lines, and crow’s-feet, fat can be removed from your abdomen, thighs, or other areas and be injected into your face. Acne scars and sunken areas of the face, lips, and cheeks can also be filled in. It can be used minimize lines between your nose and mouth, and improve forehead wrinkles.
Breast augmentation: If you desire a modest increase in breast size, you are a good candidate for fat grafting to the breast, but your breasts should already have a nice shape and good skin tone. If you have poor skin, sagging breasts, or want a significant increase in breast size, breast augmentation with fat transfer may not work for you.
Breast implants plus fat grafting: If your breast shape needs optimizing during a breast implant procedure, fat grafting can be useful. If you have residual breast irregularities after undergoing breast augmentation with implants, the irregularities can be filled in with fat to produce a smooth contour and an optimal shape.
Hand rejuvenation;Fat injection is very useful for rejuvenation of dorsum of hands.
Over time some of the fat may be absorbed which results in loss of some volume. With the latest technique of fat microinjection, in which Dr.Anup Dhir specializes, the chances of this are very low.
Even though the procedure sounds simple, a lot of experience and expertise is required to achieve good aesthetic results.Fat grafting can be used to improve surgical scars and post burn deformities as it has regenerative potential and produces angiogenesis. ADRC's or adipocyte derived regenerative cells can be separated by a special process and used either with fat or alone to treat certain deformities.There is a lot of future potential in fat grafting & it will be extensively used in regenerative medicine in coming days.
