I just had a chin implant and I'm not real happy with the results. My side profile looks okay but from the front I can see dents on the sides of the chin. I think the implant is too short. I can palpate the implant and it ends before the marionette lines. Should I be looking into the extended anatomical or the pre-jowl chin implant? Will the pre-jowl chin implant make my face look rounder or more squared? The right side of my face is rounder than the left side. Will this affect the results?
