OP, you look fine and normal, you have no functional issues, do you really want to have jaw surgery? This is major, risky surgery where bones are cut etc., lots of potential complications, and anybody that tells you the chance of nerve damage is zero is lying. You can get very lucky but the chances of no nerve damage / no lasting numbness at all are very low. I personally think people should only have jaw surgery if they feel that the potential benefits are worth the risk of nerve damage / numbness.
