Can Nose Tip Move to One Side After Rhinoplasty?

It is too early to tell whether this is due to swelling or scar contracture to one side. Time will tell, but sometimes as the nose heals scarring can cause the nasal tip to go to one side or the other. Your doctor should be able to evaluate this at 1 year.

Being that you are in the early postop phase, it would be difficult to tell if the asymmetry was from swelling or created anatomically at the time of surgery. For any asymmetries related to swelling I usually recommend a regimen of taping.
If you are less than 4 weeks postop, asymmetries related to bone position may be able to be gently changed. You will have to see after one year what your nose looks like. Small, fixed deviations can be camouflaged with injectible filler if necessary.
Good luck. Dr. Shah
