5 years ago, I had a square jaw reduction surgery through an incision in the mouth. It was very difficult at the time, but I forgot about it. The big swelling went away in 1-2 weeks, but it was still swollen for about a month . The feeling of having candy on my cheeks lasted quite a while. Six months? 1 year? After about a while, the feeling of the candy bite has weakened, but it doesn't seem to go away at all. Other than that, I'm satisfied with the surgery. I really hated the square jaw, but now I don't have a square jaw, but I would have done the same with the cheekbones .
