Question: What is the purpose of the centrifuge in the fat transfer procedure? And how long after fat transfer can I expect to see results?
Answer: Fat transfer to the face has become a frequently requested procedure. The results of well performed autologous fat transfer are very satisfying for the patient and the surgeon. The major issue with fat transfer is being able to predict the exact amount of transferred fatwhich will survive in the transferred site. Most surgeons expect about a 20 percent reduction in the volume of transferred fat from the time it is injected to a few weeks following the procedure. Experienced surgeons are careful not to over inject the recipient site with fat as this transferred fat is very difficult to get rid of. What we have learned over years of studies in fat transfer is that the higher the concentration of pure fat, and the less trauma to the individual fat cells, the better the survival of individual fat cells. When fat is harvested from places like the abdomen, hips, or thighs, the fat is in a solution of blood and damaged fat cells. Centrifugation allows us to get rid of the impurities of the aspirate and harvest a highly concentrated mixture of pure fat cells which is the best substance to inject. The results of the fat transfer procedure can be realized immediately, however, because well performed fat transfer requires numerous injections of fat into the face, swelling and bruising will be present and last for a few weeks.
