nose/chin effects of surgery

[Guest guest]

I was wondering how much of a change that orthognastic surgery has on

the appearance of one's nose and chin. My oral surgeon wants to slide

my lower jaw back and my upper jaw forward (the latter will have more

of an effect on my nose). My nose is already a bit broad to begin

with, so will such a procedure make it that much broader? Or is the

change in nose/chin appearance only temporary following the surgery

due to swelling?

I'm not sure if I should have these additional cosmetic alternations

done or not. If the change is noticable, then I probably will. Any

advice would be most welcome!
