Buccal fat repair and loss of cheek and temple volume. Which treatment can give my youthful volume back?

I used to have full cheeks and temples but an endoscopic procedure damaged my temples and the way my cheeks were lifted I lost some volume. When the surgeon corrected with a deep plane lift he removed Buccal fat (looks terrible). In order to repair which is best….Renuva, sculptra, fat grafting or another filler ? Want my youthful volume back
