Fat that dies with BBL--where does it go?

Of course, there will always be surgeons who claim 60%, 80%, or even "near 100%" fat graft "take" and long-term retention, but even a lay person knows there is some trauma in removal of the fat (dead cells, free lipid), as well as blood, local anesthesia, and other cellular debris. Then there are the technical factors of placement to achieve adequate blood supply to those cells that DO make it there alive, so they STAY alive. Too much fat injected in one spot and there is inadequate oxygen and nutrients for all the cells in the injected glob to survive. Some of the fat ALWAYS dies. This has been studied and the honest science has pegged the survival at about 50%. 

To claim more fat survival is usually puffery.

The dead fat cells are reclaimed by the body's macrophages, white blood cells that are "scavengers" for your body, and large(r) lumps of dead fat can calcify and turn into scar fibrosis (lumps and hard spots that can dimple and retract overlying skin). This is why technique (and perhaps honesty) is important. Best wishes! Dr. Tholen

Fat Grafting to the Buttock

When using fat to augment your buttock, each patients fat retention will vary. What fat your body does not retain will be metabolized.  It is best to seek a Board Certified Plastic Surgeon to do your procedure.  Make sure you look at reviews and before and after photos before making your decision with who to go with.

it is well accepted that around 40% of the fat cells will not survive in a fat grafting procedure, this depends on many variables: technique, postoperative care, nutrition and health factors. However, the data about survival is, at best, anecdotal, meaning there is no way to demonstrate those numbers.The fat that do not survive is remove from the body by the normal inflammatory process (macrophages), when the surgery is performed with the micrograph ( small fragments of adipose tissue) the chances of having lumps of dead fat cells is very small, when larger fragments are use or injection of too much tissue in a place, that is when lumps of fat necrosis are seen.Like any other cosmetic surgery, the most important factor in obtaining a good result from your surgery is the surgeon you elect to perform it. Be sure you elect a surgeon member of the American Society for Aesthetic Plastic Surgery.

BBL fat retention

In my practice we see over 80% of graft take and retention at one year.  It has to do with patient age, physiology, non smoking, procedural instruments and minimal manipulation of the fat with minimal time out of the body and with reduction of post op swelling.
