Nostrils look significantly uneven. Can I avoid a 3rd revision rhinoplasty? (Photos)

You are still very swollen. Most revision rhinoplasty patients (in my practice) require 2 years of edema (swelling) management / observation after surgery to see the final result. Some of the asymmetry may be related to the swelling. I would definitely express your concerns with your revision rhinoplasty surgeon. If you are concerned that the journey/recovery is not going as you anticipated after your discussion...I would recommend a 2nd or even 3rd opinion from an American Board of Plastic Surgery cetified plastic surgeon with extensive expertise in rhinoplasty (especially revisions).

Hello! Thank you for your question.
As far as I can see from your photos full equality can never be achieved due to facial asymmetry. After consulting with your surgeon on the subject, it would be correct to talk for revision rhinoplasty after your 1st year has expired.
Best Regards!

It is almost impossible to achieve nostril symmetry. Any attempts can lead to taking too much off one side and then going back to take some more from the other side. As this goes on permanent scarring with poor healing can lead to worst asymmetry than before the surgery was done.
Also, it is very important to remember that nobody will look at your nostrils from below. From the front view the nostrils don't look as asymmetric as from below. Unless the asymmetry is really obvious and disfiguring, it should be left alone.
