This is one of my biggest issues with the movement towards contour - where some people feel that the answer is always "buccal fat pad excision". In most patients, adding volume to the mid face, rather than subtracting it from the buccal area, greatly improves the natural aesthetics of the face and gives a youthful, heart shape. My rant aside, without pictures, it is hard to determine. Often times when doing fat grafting, a lot is used to help recontour the cheek and lateral jawline area. Everyone is a little different, and the most important thing to remember is that 1cc of fat does not equal 1cc of filler. They function intrinsically differently. All these things should be discussed with your doctor prior to the procedure just so everyone is on the same page. Best of luck to you.
With good photos it is impossible to give any opinion.You need to discuss this with your surgeon during planning.
