Why are my nostril wings uneven after my revision?

Despite a well planned rhinoplasty or revision rhinoplasty, it is next to near impossible to guarantee symmetry between the nostrils. It is unlikely over usage of muscles of facial expression would cause such a disparity. As long as the nostrils are close and the outcome is good, I would concentrate on the positive aspects of your rhinoplasty.

Although it is possible for repeated muscle function to influence healing after rhinoplasty, the most likely cause of this is pre-existing facial asymmetry
