How Can I Fix The Loss of Supra-alar Crease After Rhinoplasty on One Side?

Faces are not perfectly symmetrical and neither are noses.  You have already had two revision to try to fix a minor assymmetry that most people will never notice.  It sounds that this seriously bothers you but the risk of having too many surgeries is to cause a worse problem that can lead to an obvious deformity or difficulty breathing.    Please consider the possible risks before flying anywhere on a promise by someone to fix something that is difficult to do and has already failed in the past.

In my opinion, this issue is one that does not have a significant negative aesthetic impact on your nose.  Equally important, given your past procedures and the anatomy of this area, it would be difficult and fraught with risk to try to deepen this crease.  For these reasons I would highly recommend you do not pursue treatment for this issue.  In these type of situations, one must shift one's thinking from "how can I make this better" to "how can I accept and be at peace with what I have."  

To create an alar groove cartilage and/or would need to be resected and a bolster dressing used.  This however may create nasal obstruction.  A better option may be to graft the opposite side for better symmetry and function.
