Is it possible to have fat grafting after fillers?

I recently consulted with a surgeon about the possibility of getting fillers for a year or two and then full facial fat transfer. My problem area is mainly under the cheekbones. His preference is to do one or the other - for reasons that the scar tissue from the filler injections can affect the outcome of the fat transfer. Do surgeons who perform full face fat transfer believe previous fillers affect results. i have already had cheek/temple fillers previously in any case.
