Understanding Fat Grafting: Is It Reliable?

With the New Year upon us, many will resolve to exercise more or start a diet in order to lose those excess pounds or fat we’ve accumulated over the years. Too much fat in the wrong place leads to a flabby tummy, ‘love handles,’ full thighs, a fatty neck, etc. But fat isn’t always a negative thing. In fact, in the right amount, fat makes our face have a youthful richness, helps give fullness to a woman’s breast, and produces a youthful, round bottom. With fat, just like real estate, it’s about location, location, location.

At the Emory Aesthetic Center, we offer a technique called autologous fat transfer or fat grafting to help improve appearance, address early aging, and just make you feel better about yourself. Below are some common questions to help you make an informed decision if you are considering undergoing this type of procedure.

What is Autologous Fat Grafting?

Fat grafting is a relatively new technique that is growing in popularity each year due to the beautiful, natural results it produces. A fat grafting procedure transfers fat from areas in which you have excess fat, and injects it into areas that may be lacking in volume. People who are dissatisfied with the volume and contour of the buttocks, face, hips, breasts, or abdomen can have their own fat transferred to these areas, improving the appearance of both areas in the process.

What are the Common Areas on the Body for Fat Grafting?

The most common areas for fat transfer are the face, breast, buttocks and hands. In the face, fat transfer can be done alone or combined with chemical peels or excisional techniques such as a facelift. Fat is typically placed in the cheeks, nasolabial folds (smile lines), and even hollowed temples. Very little volume is needed to improve these deficient areas. Fat can also be used instead of implants to augment the breast or buttocks. These procedures require larger volumes of fat grafts and in some cases, require more than one surgical stage to get the desired result.

How is a Fat Graft Performed?

First, the fat has to be harvested and depending on where we are planning to graft the fat, the harvesting method is different. For the eyelids or face, we use tiny little cannulas or tubes to remove the fat. For areas such as the breast and buttocks, the tubes are much larger. The second step involves preparing the fat. Generally we use a sieve or strainer so that the supernatant fluid – the clear fluid that separates from the fat after the settling – is drained and the fat itself is left for grafting. That fat, we call micro-fat. The fat is then carefully injected in multiple tissue planes of the targeted area so that it receives plenty of oxygen and nutrients so it can develop a new blood supply. The fat that survives provides the soft tissue volume to address areas of need. The fat that does not survive is absorbed.

How Reliable are Fat Grafts?

The most challenging part of fat grafting is the ability to predict how much of the grafted fat the tissue will take. How much do we inject? How much will be retained? Because it is much easier and more convenient to reinject than it is to remove over-grafted fat, I tend to over correct by a very small amount, about 20 to 30 percent, knowing that not all the grafted fat will take. With experience, a qualified cosmetic surgeon will know that within his or her hands, how much of that fat will survive, so it’s less likely that a patient will have to come back for a second time of re-grafting.

Fat Grafting 101: What You Need To Know

lovely-ladyIf you are like me, you spend hours at the gym trying to get rid of it and you diet to prevent it. You know what I am referring to…“love handles”, “saddle bags”, basically the accumulation of fat on certain areas of our bodies. But without fat, our faces would appear drawn and old, our breasts and butt would droop and our hands would look like skeletons. In other words, fat is a necessity and it has its benefits. In the right location and quantity, it is a sign of youth. I am not recommending you hang up those running shoes, but at the Emory Aesthetic Center, we can reorganize this necessary fat to improve your appearance, address early aging, and make you feel better about yourself. I am referring to a technique called autologous fat transfer or fat grafting. Let me answer some common questions to help you make an informed decision when considering undergoing this procedure.

What is autologous fat grafting and how is it done?

Some refer to it as fat transfer or fat grafting, but the concept is not new and has been reported as early as 1893. Modern fat grafting did not develop however until the 1980’s with the popularity of liposuction. Today, in a fat grafting procedure, fat is harvested from the body by liposuction. The fat is gently prepared for injection back into the body, and then grafted into an area of deficit with small needles or cannulas. The fat is carefully placed in multiple tissue planes so that it receives plenty of oxygen and nutrients so it can develop a new blood supply. The fat that survives provides the soft tissue volume to address areas of need. The fat that does not survive is absorbed.

What are the common sites of fat grafting?

The most common areas for fat transfer are the face, breast, buttocks and hands. In the face, fat transfer can be done alone or combined with chemical peels or excisional techniques such as a facelift. Fat is typically placed in the cheeks, nasolabial folds (smile lines), and even hollowed temples. Very little volume is needed to improve these deficient areas.

Fat can also be used instead of implants to augment the breast or buttocks. These procedures require larger volumes of fat grafts and in some cases, require more than one surgical stage to get the desired result. Fat grafts can also be used to correct lumpectomy deformities after breast cancer treatment and contour irregularities after liposuction. Releasing the scar in these instances and filling the deficiencies with fat grafts is a powerful improvement tool.

What is the recovery?

Recovery after fat grafting alone is generally rapid and may only be prolonged if additional procedures are performed at the same time. As an example, fat grafting to the cheeks alone may result in bruising of the cheeks and minor discomfort at the fat donor site (where the fat was taken), but requires no time away from work. If this is combined with a full facelift, then the recovery may require 2-3 weeks away from work. Recovery is also longer if a larger volume of fat is transferred. For example, a buttock lift where 600cc of grafts are placed will require 2-3 weeks of recovery compared to the fat grafting of 10cc to the cheeks where you return to work in 2-3days. After an isolated fat grafting procedure, you might notice a week or two of swelling, possibly more if the volume of grafts is high. The injected areas will likely be bruised and feel firm. The sites where the fat was taken will follow a similar recovery. The incisions are small so once swelling and bruising improve, you can be back to regular activities in a relatively short time.

Are there any complications?

Complications like infection can occur but are rare with isolated fat grafting. Donor site complications such as bleeding or contour irregularities are also rare. An additional complication is “loss” of the graft. This refers to fat not picking up a blood supply and being absorbed over time. Typically we wait to judge the increase in volume for 3-6months after the procedure to ensure that the fat has survived.

If you look in the mirror, and see fat that you wish were somewhere else, fat grafting may be a great procedure for you. Come meet with one of the board-certified physicians of the Emory Aesthetic Center. We can discuss your goals and see if fat grafting alone or in combination with other procedures is right for you.

Ask the Doctor: How Do Fat Transfers Work?

Fat TransfersPatients often ask “How do fat transfers work, and do they last?” It is a very good question, and pertinent, too, because fat transfers have become very common in cosmetic surgery over the past several years. Fat transfers have assumed an important role in facial rejuvenation, breast augmentation surgery, buttock enhancement, and the secondary treatment of body contouring deformities, so it is important to understand what is going on.

Fat transfer is a lot like the old real estate saying: It’s all about location, location, location. Most of us have extra fat in areas we don’t want, and the beauty of the fat transfer is that we can remove some of this unwanted fat and relocate it to where we want to enhance volume. Even though this concept is quite simple, the actual way the procedure is performed has taken cosmetic surgeons many years to develop. We are still constantly improving and enhancing our techniques as we get a better understanding of how these techniques affect the survival of the fat in the new location.

The first step in fat transfer is to collect the fat from the donor site. The most common location where we harvest fat is the tummy, but we can use many potential sites, including the love handles, the thighs, and the back of the arms. The fat is collected by liposuction, either using a syringe system or a system with a fat collection chamber. The fluid obtained during liposuction (the aspirate) is then treated to remove excess fluid from damaged fat cells so that concentrated fat is ready to inject. There is significant variability in how surgeons prepare the fat for transplantation. This prepatory step can be as simple as gently straining the aspirate, may involve washing the fat, or may involve centrifuging the aspirate. The prepared fat is then loaded into syringes for injection.

The injection of the fat cells into its new “home” is done using fat grafting cannulas, these are generally small and designed to be gentle on the fat cells. The surgeon injects the fat into many tunnels and layers, as you want the fat to be widely dispersed in the tissues and not to “pool” in one area. Pooling leads to a decreased “take” of the transplanted fat. To explain this further, I like to use the analogy of planting seeds. Like seeds, the fat grafts need to get nutrients from the bed in which they are planted in order to survive. If you plant a full bag of seeds into a single hole in the ground, the seeds in the middle of the “pool” would not be able to get their roots into the dirt and would eventually die. That’s how it works with transplanted fat – if you put too much in one place, the cells in the middle will die and will be absorbed by the body.

When fat cells survive in their new location, they are there forever, and will be of stable size (unless you gain or loose a lot of weight). Cosmetic surgeons love to argue sometimes about the best way to harvest, prepare, and transplant the fat in order to optimize graft survival, and although we’ve made tremendous progress (fat transplantation is now highly effective and reliable – probably in the range of 70% survival), I don’t think we know all the answers yet. Be cautious if you feel you are being sold a “magic solution” for fat grafting, as these are often not backed up by good clinical evidence, at least currently.

One more word of warning relates to “stem cell fat grafts.” Stem cells are a current hot topic in medicine, and indeed stem cell science has tremendous potential to change the way medicine will be in the future. All tissues – including fat harvested for transfer – have stem cells anyway. However there is currently no compelling science to support the clinical claims of any special stem cell fat transplantation techniques in aesthetic surgery, and there is a lot of deceptive advertising to entice unknowing patients. In fact, both the American Society for Aesthetic Surgery and the American Society of Plastic Surgeons have issued a joint statement emphasizing this point.

The physicians at the Emory Aesthetic Center keep up with the latest developments in fat transplantation, and we’d be happy to help you figure out how they can work for you.

Fat Grafting: How Your Own Fat Can Be Transferred to Give You the Look and Shape You Want

Body GraftingBody fat…we love to hate it. We try so hard to make it go away. Too much fat in the wrong place leads to a flabby tummy, ‘love handles,’ full thighs, a fatty neck, and in men, feminine appearing breasts. However fat has another side…a positive side. Yes, I said it – a positive side. Fat, in the right amount, makes our face have a youthful fullness, helps give fullness to a woman’s breast, and produces a youthful, round bottom. With fat, just like real estate, it’s about location, location, location.

As our faces age, we can develop somewhat sunken temples, flat cheeks, thin lips, and more hollowed eyes, all related to a loss of soft tissue volume. Not only does this loss of volume affect contours, but it also contributes to making the skin look looser. As women age, they sometimes lose volume in the breast, which also can make the breasts appear droopy (ptosis). In the buttock area, sometimes we are born with flat bottoms, but sometimes bottoms flatten with aging or weight loss.

Over the past several years, cosmetic surgeons have developed better and better techniques for fat transfer. In a fat transfer, or “fat graft” procedure, fat is harvested from the body by means of liposuction. The fat is gently prepared for injection back into the body, and then is “grafted” into position using small cannulas or needles. The fat is placed in the appropriate position and tissue plane so that it gets plenty of oxygen and nutrients as it develops a new blood supply. The fat that survives the transfer process and grows a new blood supply will survive long term to provide the soft fill needed to correct volume deficiencies. The part of the fat that doesn’t survive is simply reabsorbed.

The most common areas for fat transfer are the face, breast and buttocks, although sometimes fat is placed into aging hands. In the face, fat transfer can be done alone or it can be combined with excisional procedures such a facelift, blepharoplasty (eye-lid tuck), or brow lift. Fat is most commonly used to fill out a flattened cheek, deep nasolabial lines (run from nose toward corner of mouth), the groove underneath the eyes, or sunken temples. In the face, only small amounts are generally needed to get the right result. On the other hand, buttock augmentation with fat grafts, often referred to as the “Brazilian Butt Lift,” requires larger volumes, and in some instances, may require more than one surgical stage to get the full, desired result. One area where fat has proven particularly helpful is in the correction of contour irregularities that sometimes occur after previous liposuction procedures. In these instances, moving the fat around to fill in the depressions is a powerful improvement tool.

Recovery after a fat graft procedure is generally rapid, although this depends on if any other procedures were performed at the same time. For instance, facial fat grafts in combination with a full face-neck lift will take longer to settle than facial fat grafts alone. Typically after an isolated fat graft procedure you might experience a week or two of swelling, perhaps a little bruising (but often not), and the injected areas may feel firm for a few days. Since incisions are very small, after the swelling and bruising subside you can usually be up and working out in relatively short time. Complications like infection can occur but this is very rare with fat grafting procedures. Another potential complication is “loss” of the fat graft. In this instance, the transferred fat simply doesn’t seem to grow its new blood supply and hence melts away over several weeks. A good rule of thumb is that whatever volume that you have present at three months after surgery is the volume that you’re going to keep.

Of course everybody is different, and every BODY is different. Let the physicians at the Emory Aesthetic Center talk with you about your goals, your unique situation, and create a plan to fit your specific needs.
