Accidentally sneezed through nose 13 days after rhinoplasty. I'm so worried this might affect the outcome of my surgery

You are probably okay at this point of your recovery. However, follow up closely with your surgeon to ensure the best results.

I would say at this point you are doing fine and sneezing probably didn't hurt your rhinoplasty results.  Follow up closely with your surgeon and double check but I'm confident you are fine.In general sneezing and blowing of the nose is ok around the two week post operative day.Chase Lay, MDDouble board certified facial plastic surgeonAsian Facial plastic specialist

At this point, you are probably ok. Your surgeon can examine your nose at your next postop visit. In the meantime, try to remember to sneeze with your mouth open to decrease the pressure it causes.

It is unlikely that you caused any permanent damage by sneezing through your nose 13 days postoperatively. It does not surprise me that you experienced some pressure and discomfort as your nose is still healing and tender. If you feel your nose looks different or doesn't feel right, I would recommend returning back to your rhinoplasty surgeon to get evaluated.
