It was about ten years ago that I first met Dr. Sidney Coleman. He had just published a text called Structural Fat Grafting and was showing his results which were superior to others I had seen. I had been studying fat grafting since 1991 when I did my first case. I immediately saw the genius behind his methods backed up by beautiful photographic documentation; I purchased his book, had him sign it, bought all of the recommended equipment and was on my way.
It was about this time that it became obvious that adipose tissue was special in ways we had never figured. Our own fat turns out to be the bodies’ primary depository of mesenchymal stem cells, rather than from bone marrow, explaining adipose tissue’s ability to rejuvenate our faces when injected into the face.
After a number of years and hundreds of cases I began to notice a pattern in our results. It became clear that our older (>60 years old) patients seemed to have much less than the 80-90% graft survival that we had become accustomed to. Others had noticed the same phenomenon (PRS 2014 August; 134(z), 227-232) but placed the cut-off at 45 years of age.
Empirically we studied the gross appearance of the suctioned and centrifuged fat noticing there tended to be a demarcation within the fat layer itself. Approximately 30-50% of the fat looked somehow different, less “cellular or robust” if you will. The location of the donor fat areas also seemed to appear different with the entire specimen seeming more cellular. Donor locations have been studied and our observations confirm that flank and upper buttock fat seem more vital than abdominal or thigh fat. For younger patients the opposite seems true.
We also believe, as do others, that stem cells from older individuals seem to lose some of their “potency” in regards to being multi-potential mesenchymal cells. The rejuvenating ability of adipose derived stem cells may age and become less potent over the lifetime of the organism. This observation has practical implications as many people are choosing to donate their adipose stem cells for possible future use as a treatment for certain diseases and possibly even cancer. It makes sense to donate one’s stem cells as early- as young- as possible to have maximum effectiveness. The cryopreservation of adipose tissue is now a growing industry requiring only standard liposuction techniques to obtain the fat which is cryopreserved indefinitely for a small yearly fee.
The TV news media is reporting the latest “break-through” in cosmetic medicine science. Evidently for a mere $4,000 one can take a punch biopsy of a patient’s skin, send it to a lab where fibroblasts are isolated, cultured and expanded. This results in millions of fibroblasts which are then re-injected into the face to rejuvenate the tissues as fibroblasts are known to synthesize the protein collagen which is lost in the aging face. This clearly is a break-through in cell biology albeit an expensive one and not a popular alternative since it doesn’t last longer than 6 months.
A different technology has been available for several years and achieves pretty much the same thing at a fraction of the cost, and it lasts forever. Adipose derived stem cells are isolated from liposuction aspirate and then re-introduced into the areas requiring rejuvenation. The stem cells are more basic precursor cells to fibroblasts thus are thought to transform into fibroblasts as well as other cell types that increase vascularity and provide many of the trophic growth factors that help rejuvenate skin. Depending on their environment, stem cells can be encouraged to form cartilage, even re-create osteoblasts that form bones. Therefore, stem cells have been used for a wide variety of clinical problems including skin rejuvenation, joint cartilage re-growth and healing, wound healing and even re-growth of cardiac muscle tissue.
All of these new technologies whether or not they are “FDA approved” need to be evaluated through the prism of overall scientific advances. It seems that the imprimatur of the FDA allows the science to be exploited for marketing gain by the few. Regardless, FDA involvement with these new scientific advances has not been well defined and tends to allow for marketing adulteration of the product in question often misleading the consumer regarding other available options
Beautiful, full, pouty lips are considered youthful. One of the natural consequences of facial aging is the loss of normal lip volume causing a deflated appearance with wrinkling. There are many misconceptions regarding attractive lips that seem to have found their way into the social consciousness due to Plastic Surgery results that seem to have gone awry. Merely increasing the size or the amount of vermillion show (red portion of the lips) does not make lips youthful or attractive. In fact, exaggerated lips seem to invoke the opposite response much like the overdone rhinoplasty, facelift, or breast augmentation. It should be clear that exaggerated Plastic Surgery is a choice, not a necessity. Plastic Surgery has progressed do the point where overdone is not mandatory and we Plastic Surgeons should question not what we can do but what we should do. Because a patient asks for bad Plastic Surgery doesn’t mean we are obliged to do it. Our role should be to educate those who ask for things we know are unattractive and if no common ground can be negotiated, no surgery should be performed.
There are details commonly associated with youthful lips that are easy to achieve as long as you know what you are trying to achieve. Full lips are youthful, grossly inflated lips are not attractive and reek of bad Plastic Surgery. Full lips require replacing the lost lip fullness with natural material such as fat. There are numerous off-the-shelf graft materials that seem easy to use, but as foreign materials they present a multitude of problems that make the result less than perfect. Autologous fat taken from the abdomen or hips, when properly processed, provides the best graft material for lips. Increasing lip volume causes some increased vermillion show (red portion of lips) seen from the front as well as increased “pout” as seen from the side. The increased volume must be apportioned so that they appear fuller and pouty. Other aspects of the beautiful lip include definition of the white roll, fully visible philtral columns, and important for a natural look, a lower lip that is slightly fuller than the upper lip. These nuances are not obtained by luck, but rather because of detailed surgical planning using the correct filler material. The results should be apparent immediately and should last a lifetime. Continued aging may lead to the need for touch-up grafting after several years even though the transferred fat, once healed, is permanent even though the lips are a highly mobile area of the face. Any perceived problems with graft “take” are generally due to poor harvesting of the fat and inadequate processing of the harvested fat. One should expect to have the fullness lost since the teenage years. It can be helpful for your Plastic Surgeon to see high school photos for reference.
