Will Accidentally Hitting the Nose Affect Rhinoplasty Results?

The bones should be pretty well healed after 4-6 weeks after surgery. Usually, when someone breaks their nose, it is pretty obvious.
Having said that, I always think it it best to be examined by your surgeon. It is impossible to know for sure unless you undergo a complete exam by the surgeon who operated on you.
I have had several patients with similar accidents weeks after their rhinoplasty. Not a single one has ever had a fracture or shift in their cartilage. So, usually it is fine. Sometimes there could be some swelling where you were hit. This might be the change you are seeing.
Again, the best thing to do is to call your surgeon, explain your situation and go in for an exam to be sure.

Without photos and an examination, it is impossible to tell.
In any event, the bones should be well healed by 6 weeks but this does not mean that you did not fracture them.
TYpically swelling will improve within 4-7 days. You need to have your nose re-assessed at this point to determine if there was any disfiguring damage caused by the injury. There is no problem in waiting up to 2-3 weeks after the surgery to have corrective surgery if necessary or required.

Although your nose should be healed by 6 weeks, any trauma to it could cause a shift in the underlying structures.  If you have any concerns, you should see your surgeon to have him/her check it.  He or she should help reassure you and answer any questions you may have about your nose.
