I'm Dr Robin Van Look, plastic and aesthetic surgeon in Antwerp,
you mention a very interesting and important question. The subject of fat reabsorption has been researched by many institutes for many years. I assisted fat transfer already more then 25 years ago in cape town.
the technique has changed a lot since ! and with that also the results. nevertheless it is difficult to tell how much is reabsorbed exactly, because it can only be examined individually by biopsy and still.
But I suppose that your question is more does the procedure need to be repeated, how long will the result last will the result stay the same or will it change over time.
In that option we can be clear, that improvement of fat preparation infiltration , specialized harvesting cannullas, cleaning of the transplanted cells adding stemcell to the transplant taking in account the amount of fat that is transplanted the acceptable tissue pressure in the area after transplantation on the surgical site, but also on the patient site nutrition after the surgery will improve the way to have maximal take of fat cells etc.
you see it is a complicated matter with a lot of different elements to account for.
What I can tell you in my experience of performing this technique for a long time is that nowadays we can transfer fat in a safe way by using a closed circuit preparation and injection of the fat. Using well adapted instruments to reduce injury to the cells; knowledge on fysiology of viability the cells allows us to achieve remarkable results even with large volume transplants.
There are indeed important differences to inject a few mlls in the face then to do a 300 cc fat transfer to bum or breast.
it also depends on what you expect the result to be. So if it is a specific question that you have for yourself and you agree to be treated in Antwerp Belgium then please send me a picture and some more info about yourself to my personal email address
