Can you help with trauma to facial fat transfer several years after the procedure?

Fat transfer after so many years will behave the same way as normal fat in your face. Therefore it could be traumatized and you can have fat atrophy. There could also be a scaring that could affect the result- this is not due to having a fat injection, but rather the fact that fat cells can be traumatized.

After about four months, any fat transfer is incorporated into the surrounding tissue. Therefore, the fat placed five years ago is essentially the same as the fat that you were born with in the area. It is permanent and respond like normal fat to anything that happens to the area. It, therefore, it is possible for the pet to be injured enough to cause problems. This would, however, happen to the normal fat had you not had the transfer. Yes, if you hit the area significantly, it is also possible to form a large hematoma which would then liquefy and become like a cyst, requiring drainage. This, however, can happen whether or not you have had that transferred to the area or not. If you were worried about the area, see a plastic surgeon for an evaluation.
