What are the telltale signs you messed up your rhinoplasty?

The question of ruining your rhinoplasty is appropriate but overly emphasized. You are right, the nose is very strong, however the newly manipulated nose fragments are fragile and have to be protected for several weeks. A light brush will not do damage. An elbow on the basketball court will be devastating. You can't play tennis, for instance, for six weeks. Wear your glasses, but be careful. The result is totally stable after six weeks and it really takes quite a blow to do some damage. There is nothing that can't be fixed if it does happen.
