Breathing problems and nose dimples after primary septorhinoplasty - nasal valve issues? (Photo)

I'm am approx 2 years post septorhinoplasty, and the middle region of my nose seems to collapse inward, making it difficult to breathe. If I push these areas out and hold them there, I can breathe a lot better. My surgeon has stated that my septum has redeviated to my left and that he can straighten it, but he does not believe that I have breathing issues on both sides. To me, it feels like there is insufficient side support. Does this look like valve collapse (both sides) or other?
