There is no question that the chin and the nose are interrelated and are best addresses together. Performing the chin operation separately or ahead of time, does not provide you any specific advantage, other than cost savings. When balancing the nose and chin, you must decide, along with your surgeon, what might be the right chin operation for you; a chin implant, a sliding genioplasty, or a chin reduction. There are advantages to an implant (easier recovery and sometimes less costly) and disadvantages (external scar under chin, possible bone loss under the implant over the years). The main advantage of a sliding genioplasty (moving the chin bone forward) is that it tends to be good for life when healed and the incision is hidden inside the mouth. From a surgeon's stand point, and when possible, genioplasty and rhinoplasty are best performed together.
