Fat Transfer: Q&A
Ask a QuestionMust Fat Be Overdone for the Body Own Absortion?
Is it true that fat injections have to be exagerated because of the body's absortion and if so how long does it take for it to go back to normal ....and if the "fat transfer is almost permanent"(80 -90%) how does it work? I'm very interested in having this procedure but a bit resistance and won't do it until i have most questions answered

Fat Transfer Must be Done Methodically
Fat transfer requires knowledge and experience in how much fat will absorbed over time. Different medical studies have showed varying results about how what percentage of the fat goes away. As a result, your surgeon should be careful in the amount that is placed. Overfilling is irreversible and is not easily corrected. The doctor performing the procedure must use proper judgement in the amount that is placed in each area. Fat transfer is an art and should be performed by those with...

Overfilling across the board is not a good idea with fat grafting
Yes, fat grafting is truly both an art and a science. Doing beautiful work requires both a good artistic eye and considerable experience with watching long-term results. That being said, fat has characteristics that must be understood if the surgeon given that he has experience with this art should abide by.
1. Overfilling to a significant degree can cause problems because there is a certain degree of variability in fat take and the last thing you want is an overfilled...

Fat injections
The amount of fat that is resorbed after reinjection will vary with technique and the location in which it is injected. It does need to be overfilled

Overfilling is required to some degree
Yes, you are correct. Not all of the fat that is injected is viable, and some does not survive. The actual percentage of survival is very difficult to ascertain. We have traditionally believe that number to be in the 40-60% range, but some claim even higher numbers now, though again, its quite difficult to actually verify that number scientifically.
In general though, overfilling is required, but it is an art at this point, more than a science. I also agree that it is not prudent to...

Fat Survival 80 to 90% Survival In Face
80 to 90% survival in the face is a general guideline. Overfilling may be indicated, but it is better to undershoot than overshoot.

Fat transfer to the face
Dear Vivian Faith,
Fat transfer is done differently with each surgeon
Personally, I have certain techniques and amounts I inject to avoid overfilling
In fact, since results are permanent, we can be more conservative at first and if you need more volume, a touch up can be performed
If you go to an experienced fat transfer surgeon, you will be in good hands

Overfilling with fat graft
Yes - a little overcorrection is needed, in most cases. In a recent study, using BRAVA assisted fat grafting, about 65% of the fat was retained at three months after fat transfer.
So, if you want a 100 cc change, for example, about 150cc (100 divided by .65) of graft is needed. However, this is not always possible in one surgery, and multiple procedures may be required.

Fat Transfer - Overcorrection?
Most surgeons indicate that at least some of the fat is absorbed by the body over time and, for that reason, you will have less of a result ultimately than you do at the end of the procedure. One way to address this is to overcorrect with the assumption that it will not all stay as it is immediately post-op. Another approach is to plan to do additional procedures in the future if the correction is not maintained. In areas where "you can't have too much" (as is sometime...

Fat transfer
Fat transfer is one of my favorite procedures for rejuvenating the face, either as a stand alone procedure or in combination.
The procedure adds volume and rejuvenates overlying skin. The procedure works by transferring fat from a donor site, usually the abdomen, to the face.
I overfill slightly and that is where the 'art' of this procedure comes in; location of fat placement and the amount of fat used varies between patients. Usually patients are...

Fat grafting / Fat tranplant
Fat grafting is excellent for restoring volume to areas which are sunken or deflated and the results can be spectacular when done correctly.
When fat is transplanted from one part of the body to another, certainly not all of the fat cells will survive.
The fat injections do need to be overcorrected--but the key is to overcorrect SLIGHTLY. Generally this means an overcorrection of 15-20%.
It is better to slightly under-correct and then undergo a secondary procedure to...
