Facial fat grafting relies mainly on the establishment of blood circulation in the grafting bed, which ensures the survival of the grafted cells. From surgical practice, we have found that if fat grafting is performed in the same area where the surgery was performed, as long as the local scarring or local tension is not particularly heavy, it will help the fat cells to survive, and not only does it not reduce the survival rate of fat grafting, but it will increase it instead. In the process of fat grafting, usually the survival rate of the first filling is relatively low, but the survival rate of the second or third time will be significantly improved, because after the first surgery, the local establishment of a lot of blood vessel buds, and then fill the fat, the blood circulation will be established faster, and the survival rate will also be improved. So if the filling is done again due to excessive liposuction of the face, the survival rate of the filling is generally good. If there is any localized unevenness, it can also be improved by repairing it at a later stage to achieve a good repair effect.
