Fat Transfer / Fat Injection / Fat Grafting

Dr. Ben Talei, a dual board certified plastic surgeon at the Beverly Hills Center for Plastic & Laser Surgery is a dedicated specialist of facial cosmetics, reconstruction and rejuvenation. He has developed a significant number of uses for fat transfer and fat grafting to treat a variety of needs. Dr. Talei is also a specialist in revision fat grafting, often treating patients who have had suboptimal outcomes.

How Does Fat Grafting Work?
Fat transfer has many uses based on the utilization of fat for volumization and camouflage, as well as using fat for its regenerative potential. The source of fat varies, but it is most commonly taken from the anterior abdomen by means of liposuction and micro-liposuction. The use of micro-liposuction cannulas decreases the risk of irregularities. Other areas such as the inner thighs are commonly used as well.
Next, the fat is immediately purified and injected with micro-cannulas into the intended areas. This can easily be done under local anesthesia. Although, many patients elect to receive some form of anesthesia. Fat grafting is extremely technique-dependent, meaning results can vary significantly from provider to provider. In general, younger patients tend to have a higher take rate for grafting integration, but this is not always the case. For the individual patient, the probability cannot be accurately predicted despite data presented by published studies.
Multi-level fat grafting is the most commonly used technique. This places fat cells (adipocytes) into different tissue layers increasing the chance of graft survival and decreasing the chance of irregularities. Once the fat cells integrate, they can grow naturally with the body just like the surrounding cells. Because take rates vary from patient-to-patient and side-to-side, many practitioners treat fat grafting as a staged procedure. Instead of addressing the entire region with one procedure, the final result is sometimes best achieved using two or three procedures. More fat can always be injected at a later time, but the fat once integrated is difficult to remove.
In situations where a larger volume of augmentation is needed, such as with atrophic or sunken defects, dermal fat or composite fat grafts may be used. This involves the removal of a larger segment of fat with or without the use of the overlying skin. This type of grafting is very useful and successful with the only limitation being the thickness of the graft.
Do I Need Fat Grafting?
Fat grafting can be used for cosmetic purposes as well as reconstructive. Fat grafting is a wonderful procedure to use in facial rejuvenation. As people age, the fat pads on the anterior cheek tend to droop with gravity. Some patients may also experience volume loss, although this is not the case with all patients. The patients most commonly encountering volume loss are those with recent weight loss or a high muscle-to-fat ratio, such as those avidly involved in weight training and exercise. This may cause a gaunt appearance with flattening of the anterior cheek and deepening of the tear troughs and under eyes. Fat can be harvested and replaced in multiple planes in the cheek both laterally and anteriorly. Care must be taken to avoid superficial injection near the tear troughs where irregularities are commonly seen following fat transfer.
Another area where caution must be used are the lips. Although dermal fat grafts and lateral SMAS grafts demonstrate outstanding results, micro fat transfer with cannulas should be performed judiciously, if at all. Irregularities are sometimes seen with free-fat injections and are difficult to repair.
The reconstructive uses of fat grafting include patients with lipodystrophy, facial asymmetry, hemifacial microsomia, facial paralysis, bony defects and even in burn patients. Fat grafting in burn patients has shown promising results by improving contracture from deep scarring.
