The latest rage in Plastic Surgery is fat transfer or fat grafting. Fat transfer to your butt, breasts, face and lips – really wherever you need volume. Fat has a number of advantages to its use. Firstly, the fact that it is harvested via liposuction techniques allows you to rid yourself of unwanted fat in certain areas in your body. There is no risk of rejection as it’s your tissue and it’s free – well at least the fat is, getting it is a labor-intensive process. As we age, we lose volume, and many patients are born with deficiencies where they could use more oomph.
Well, what’s the down side? Fat grafting is a procedure where we remove tissues from where they live with a bloody supply, nutrients and oxygen and then re-inject them in another area hoping they survive long enough for new blood vessels to reconnect. The fat cells need to survive by diffusion – absorbing all the food and oxygen – until they are supplied by another, new blood vessel. Unfortunately, about 40-50% of all of these cells will die before this happens. Once this fat cell hangs around long enough to get its own capillary, it will likely survive forever. Permanently becoming part of the new location.
If we are going to lose half of the fat grafts, why not just put in twice as much? Great question, and here’s why. The diffusion process relies on the fact that each “grafted” fat cell is near a blood vessel or other cell that it can borrow from for awhile. The bigger the injection of fat, the more likely the fat is going to be next to more fat and will not survive. Thus, all we end up with is more fat loss.
It seems really complicated. How do we make this work? The success lies in a technique called micro-fat grafting. Meaning that very small amounts are placed in different layers of the skin and muscle to increase the chances that each fat cell is close to another cell it can borrow from. The more this happens, the better the overall success rate. This leads to increased volume and happier patients.
What’s next? Next on the horizon is the use of adult stem cells to enhance the survival of the fat grafts by making them “super-charged fat grafts.” The stem cell effect is still under investigation and not currently approved outside of a study in the US. Stay tuned for our next blog post where we will discuss the latest on stem cells and their use in cosmetic surgery.
