I had extensive orthognathic surgery performed on my jaw and cosmetically had a piece of my chin moved forward 15 years ago. I would like to have the length of chin reduced now by about a half or so centimeter. I have attached recent xrays. Is this something a credible would feel comfortable attempting-due to the weakened structure? Would anyone recommend a New York Surgeon in Chin Reduction? Most Surgeon's sites don't even mention this. Thank you!
