Why do my nostrils look bigger after rhinoplasty?

It is common for the nose to look a bit turned up after surgery.  This typically goes  down as the swelling resolves.   There is no way to make any judgments on the results at 7 days.   

Thanks for your question. It's entirely possible that the change in the size and shape of your nostrils is temporary. Swelling can be unpredictable, and we do see this sometimes in the early phases of recovery. At any rate, it's far too early to worry. Give your nose some time to heal. Over the next few weeks and months, your swelling will reduce significantly, and you'll have a better idea of what your permanent results will look like. Good luck during your recuperation.

The nostril might be pulled up due to the taping of the nose and often come down with time. They can appear thicker due to swelling.
