What happens if I injure my nose after rhinoplasty? For example falling on my face or walking into a wall.

Hello! I am contemplating whether or not to get rhinoplasty in the future, and there's a thing I've been wondering about for a while now. See, I like skateboarding, but with skateboarding there comes a risk of injury. So basically my question is, if I for example fall on my face after rhinoplasty (fullly healed ofcourse), what will happen?
