Fat grafting , properly performed, can have a long-lasting results. Agree with previous poster that the surgeon must focus on the viability of the fat grafts.
Early fat grafting techniques had less than desirable outcome. The long term survival was poor and the incidence of irregularities was high.
With proper attention to harvest and implantation (you can call it many names, but it really depends on what the technique does) one can achieve fat survival rates of 50-80% (at least in my hands)
The location of the fat grafting influences the longevity. Better longevity in lower eyelids and cheeks (~80%) and lower in the lips and surrounding area (50%)
Better health may have an indirect effect on survival. However, in the early postoperative period it is important to protect the area from repetitive impact and prolonged edema.
If you consider fat grafting to correct Artefill removal defects, it is better to wait until the swelling has subsided after Artefill removal
