Platelet rich plasma (PRP) is the procedure where your own blood is centrifuged (spinned) and all the growth factors are collected. The process takes less than 10 minutes to collect the plasma. It is known that growth factors are very important for wound healing. Fat transfer requires optimal conditions for the fat to survive. Theoretically, adding your own growth factors to the fat will increase the changes of fat survival by improving and stimulating the surrounding soft tissue to support the “take” of the fat.
Now, there are multiple studies that have shown that it might be beneficial to add PRP to the fat. There are also other studies that have shown no difference. In other words, results are controversial.
I routinely use PRP and mix the growth factors with the fat prior to transplantation. The cost is around $300.00. If it does not hurt the patient, why not use it? There is some evidence that it might help. Typically, I have a survival rate of more than 80% of fat injected. Now, does PRP help improve the survival of the fat or is it my experience and technique? I would not be able to answer this question unless I make a longitudinal study. It would require me to inject fat on one butt cheek with PRP and fat and one butt cheek without PRP and compare the results over the long-run.
