Rhinoplasty

I'm 26 and interested in a rhinoplasty and I've hear mixed reviews about my friends' success. I've had two friends get rhinoplasties done and one had to get her's fixed a few years later. She told me that this was common, but how could such an intense surgery be so common to have to fix? Also, how risky is it to have the surgery done multiple times? Finally, does the "fixing" procedure cost just as much, or less, than the original on average?

Thank you Doctor!
