You have an atypical chin structure and your subjective concerns are anatomically justified. Better views are needed but seems your atypical chin needs a very specific and custom design of osseous geniplasty, with juditious preoperative discussion and planning. If few surgeons have experience in osseous genioplasty... fewer in custom designs; this is my planning advice for you:-beware of retrocession or backwards sliding genioplasty! do never accept such!!! sliding the chin forward is amazing, good, and provides some beneficial "side effects" like reducing the jowls and reducing the double chin or flaccid neck, due to its tightening effect... but sliding backwards is disastrous and makes double chin appear and jowls appear; if you are suggested this do change to next door-you need chin reduction, in anterior sense, not sliding backwards! as mentioned before; this is accomplished by a vertical or somehow oblique osteotomy and then slicing the previously measured slice of excessive bone-your chin has another issue, as important as its prominence but not mentioned by you, and IMHO even the most important: vertical microgenia, it is tiny vertically, out of proportions to your, otherwise, well balanced and beautiful face; it really requires as a must vertical lengthening; doing only deprojection of the chin would leat to a grotesque microchin of hateful proportions; the bone grafting for the vertical increas could be taken (totally or in part) from the prominence reduction, or maybe supplemented with elbow (better) or hip grafting.-I'd like to see your frontal view (if possible via private communication), to assess if eventually (as I guess) your chin might need as well an horizontal modificationYours is a case in need of a good osseus genioplasty expert with skills to perform a custom case which requires not that much manual skills but massive amounts of good aesthetic judgement and preoperative planning; may be a three-dimensional custom osseous genioplasty.
