I had asymmetry after my first jaw work, so against my better judgement, got a chin implant with jaw revision. Well I had the chin implant taken out, I hated it AND literally once the swelling went down from the removal I returned to the same asymmetry. The surgeon didn't "contour" anything. So anyway because of nerves, I've heard the work that can be done in the chin area is limited. Surgeons just don't say that beforehand.
