Liposuction under the chin – submental liposuction – works well to thin the neck. But liposuction of the face does not work. However there are two marble shaped pieces of fat in the cheek called "buccal fat" which can easily be reduced. Buccal fat is the fat that gives babies their chipmunk appearance. But that look can exist even in thin adults. With a small incision inside of the mouth, a small amount of this fat can be removed through a procedure called "buccal fat excision." By removing the bulge in the lower cheek, the face can be made to look much leaner. Because facial fat is lost as we age, plastic surgeons must be careful not to remove buccal fat without careful consideration as to whether that person has so thin of a face that they may look too thin after face is lost in the future. For the many patients who undergo buccal fat excision, they enjoy a much leaner appearance, and the surgery leaves no tell tale signs that anything was ever done.
