I recently had a consult with a max/fac surgeon about the type of jaw surgery I needed to fix my gummy smile and lower jaw prognathism. He said he would move my upper jaw straight up 5mm because if he was going to rotate it my lower jaw would stick out 8mm more than it does now which is no good. He also said he would move my upper jaw forward 2mm and setback my lower jaw along with a genioplasty. He didn't have a projected result and he said the changes would be subtle but I really would like a shorter face. His assistant made it sound like my case wasn't all that bad and seemed to try and talk me out of it. So my question is how noticeable will the changes be?
