Never had mine broken but my brother and my dad both had serious nose breaks. I'm pretty sure that the doctor just sets it straight, (OUCH), and there is a lot of bruising and swelling till it heals up.
I'm with Fint on the "wear it with pride" deal. My brother's came from the rifle butt of a cop in a very corrupt regime part of the world while he was pleading for the release of a hostage.
