Radiesse can be used to fill around the nasal hump

Hi, I'm 21 years old, male and considering Rhinoplasty. I am unhappy with the appearance of my nose, but only really when I smile (a big toothy grin particularly). I would look to correct a small hump (Is this a "dorsal hump"?) on the bridge of my nose. It's not bad and my nose isn't overly wide, so could this be done by just filing or rasping it down?

I've read a lot about this on the Internet but I never know what to believe! My other concern is that my nose seems to widen when I smile ("Pic.4" shows the areas on the side I don't like). Why is this? Would I need work on the tip as well to stop this? ne of my main issues, however, is recovery time because as a singer, management doesn't want a huge recovery time! Thanks, from a confused guy!
