Crooked nose in certain lighting after rhinoplasty (6 years post OP). Can it be fixed with fillers or only revision?

Hello, I am currently 6 years post my initial rhinoplasty. First year or so, I did not notice any crookedness, but it seems as years have gone by, there is some odd collapse and shadowing in the left side of my nose that wasn't there before. Can anyone advise why that might happen? Can it be fixed with fillers or only revision?
