One month post op and it appears that my nostrils alternate when I breathe after Rhinoplasty. Is this normal?

I am pleased that you are happy with your surgical outcome.  You are experiencing what is the normal nasal cycle.  The nasal mucosa, and more specifically the inferior turbinates, will swell and shrink throughout the day and this cycle will alternate sides.  If nasal congestion is an ongoing issue you may be a candidate for an in office procedure to reduce your turbinates.  If your surgeon is experienced in the functional aspects of your nose they will be able to evaluate you for this procedure.

Intermittent congestion is normal one month after rhinoplasty.  Cyclic or alternating congestion is also part of the normal nasal cycle.  I suggest you followup with your physician to rule out any other issues causing nasal obstruction, but from what you are describing this all seems normal for the recovery process.  Good Luck!

This sounds completely normal.  What you are feeling is likely due to swelling of the inferior turbinates.  These are structures inside the nose along the side wall of the nose.  You can think of the inferior turbinate as a small shelf of bone wrapped in soft tissue.  These structures shrink and swell more than anything else inside the nose.The back and forth nasal obstruction that you describe is common.  There's actually a name for this -- "the nasal cycle."  It's normal for the turbinate on one side to swell and have the opposite side shrink at the same time.  This varies from side to side and also varies at different times throughout the day.You are probably noticing this more for two reasons.  First, you're only a month out from surgery, so as you already mentioned you still have some swelling and generalized inflammation inside your nose.  The second issue is probably that you are just so much more aware of everything related to your nose and breathing through it since you have just had such an important operation.Without examining you there's no way to tell if anything else may be contributing, but be reassured that what you described seems common and not worrisome.  Keep close follow up with your surgeon, and best of luck as you continue to heal!
