When does the majority of swelling in a nose go down after rhinoplasty?

You are still early in your recovery period and the nose is expected to be quite swollen at this point.The swelling during this time is rarely symmetric. One side will always resolve more quickly than the other. The majority of the swelling will resolve in 3-6 months, and will continue to resolve as your nose heals for up to 1-2 years. You have not reached your final shape as the nose will continue to heal and reduce in size for up to a year. Once it does reach its final shape you may be more pleased with the appearance of your nose.

The answer depends on a few things.  First it definitely depends on the approach.  Closed rhinoplasty swelling generally goes down much faster than open rhinoplasty.  Also the maneuvers performed during surgery can influence how long swelling sticks around.  Your surgeon should be able to give you a better idea.  

Hello,
As you rightly say, the swelling takes over a year to go down. The swelling in the upper nose improves quicker than the tip which takes longest to improve. Most of the changes are early on within the first 3 months but minor changes are still expected after that time. You can take regular dated photos to monitor the progress for reassurance.
