The buccal fat pads are located in the lower portion of both cheeks, and in some patients large buccal fat pads can create chubby "chipmunk" cheeks. Removal of these fat pads or reduction in their size is typically performed through an incision on the inner surface of the cheek. This procedure is not appropriate for everyone, and patients should be very carefully selected. As we age, we lose some of the fat in our face naturally, which is part of what makes a face look older. In the incorrectly selected patient, removing any portion of the buccal fat pad may lead to a gaunt, aged appearance, if not initially then later down the road when the aging process causes atrophy of the remaining facial fat pads. There are other procedures which can provide the slimming effect that you are interested in without removing any fat, such as augmentation of the upper cheeks with fillers or implants, or Botox injection to the masseter muscles that lie over the jaw. I recommend scheduling a consultation with a facial plastic surgery expert who can evaluate your concerns in person in order to determine which procedure or procedures would be most likely to give you the results you desire. Best wishes,
