Time goes by so fast. Before the surgery, I was so stressed out about my chin that I didn't want to live, but after the surgery, I'm so happy. The hospital said there was no other way than double jaw surgery, so I worried about it and had the surgery. I had it done at an oral surgery clinic, and it was a case of correction after pre-surgery, so I had pre-surgery and correction for about a year more. Seems like?!! There are no particular side effects, just less sensation in areas such as the roof of the mouth. People don't even know they had surgery.
