Hard to say. It goes from a Class III underbite look, to normal. The upper lip seem to get more support, so probably upper jaw surgery, and it seems like lower jaw was adjusted as well. So probably a BiMax surgery. Just because someone else needed a bimax surgery to harmonize their facial structure, doesn't mean that you need it. It's very individual, sometimes it's an isolated deviation that makes the entire face look out of proportion and you s**t bricks when you see what only a genio or implant can do in some cases.
