facial sagging after zygoma reduction

I am desperately trying to search for something like this, but I feel like it’s nearly impossible. Bone grafts fail majority of the time and reverse zygoma is extremely difficult, even to the most experienced doctors. I read up that cheek implants are probably the best option, but I really am not sure I would want to go with that since it could slip or cause infection.
Has anyone found a solution to this? I went to a plastic surgeon near me and he said to fill it back up with fillers.
May I ask why are you looking for a similar solution? Is it due to FC?
