It was a long time ago, so I can't remember everything, but what is certain is that it's a lot better than before. Before the operation, the mandible was not developed much and it was an oval shape with no corners. It was closer to a cosmetic purpose than an improvement purpose. The doctor said that the effect would not be dramatic at first, but I was satisfied. It 's a lot harder than a 7-hour operation in total, it's a bone surgery, it's general anesthesia, it's both hard, so I almost died. I regret the contouring surgery, I decided I would never do it again for the rest of my life, but when time passes, I find myself wanting to do it again . I am regretting that I did not recommend doing the Accu sculpt (double chin removal) after contouring. I also want to remove forehead fat, but who knows where to do it .
