Underbite: Moving Upper Jaw Forward or Lower Jaw Back?

My surgeon said there were 2 options for correcting an underbite. Should I let my lower jaw moved back or my upper jaw moved forward? what's the best solution if I want to keep my facial features, but looking better(Golden Ratio (fibonacci))?

I'm afraid my nose get wider and pointing up by moving my upper jaw. So maybe moving my lower jaw back is better (is genioplasty necessary?) I also want to take lefort 2 surgery in consideration. but think my surgeon won't do that

I would not recommend a mandible setback - your problem is that your mid face and maxilla didn't grow, not that your mandible grew too much.... more
