If I get rhinoplasty, can it effect the hole of my nose piercing at all?

You shouldn't have piercings for at least 2-4 months. Then, if you talk to your surgeon and get approval, there is no obstacle to having a piercing. 

The exact answer to your question depends on what kind of rhinoplasty you are having. If you are only removing a dorsal hump, for instance, that procedure probably would not affect the placement of your nasal piercing. If you are undergoing tip refinement, or narrowing your nose, it's quite likely that the position of your piercing hole would change. However, you can always re-pierce your nose after surgery or even have it done (and the other hole closed) as part of your procedure. Just be sure to be clear about your hopes and expectations during your consultation with a facial plastic surgeon. I hope this helps.

A closed rhinoplasty approach can accomplish making all of the required changes to the nose with all of the incisions placed on the inside of the nose.  Plan on re-piercing the nose at least 3 months after the nasal surgery
