Orthognathic surgery and sliding genioplasty or chin implant and mandibular angle implant? Which best suits my case? (Photo)

I agree with both doctors. Jaw surgery is probably the best option. maxillomandibular rotation might give you the best result. You need to consult an orthognathic surgeon.

Your best option in jaw surgery. Without it you also have a risk for Obstructive Sleep Apnea in the future.  There are a lot of good Oral & Maxillofacial Surgeons in Texas that do the procedure.

double jaw surgery and either genioplasty or chin implant, depending on the prediction tracings. If after the jaws are advanced the chin still requires significant movement, a sliding genioplasty can sometimes leave a step deformity at the lower border of the jaw. This is where I would recommend and implant instead. Now, with respect to your nose, advancing your upper jaw will change the profile of your nose (will take away the convex profile or "hump") without having formal rhinoplasty. Also, prior to closing the upper jaw incision, evaluation of the width of the alar base of the nose is done.  Advancing the upper jaw widens the alar base. If that is what you want, then it is done. If you want to keep it narrow and only want a profile improvement, an alar-cinch procedure is performed to control the width of the nose.Dr David MuellerVirginia Facial Surgery
