Nasal valve collapse: breathing difficulty and asymmetry. Can this be corrected? (Photo)

Hi doctors, I have a nasal valve collapse in my left nostril (internal/external?) that I'm getting fixed soon with septal cartilage grafts. The collapse is causing my left lower lateral cartilage/nostril rim to sink in & downward, with a triangular shape to it. There's a dent on the side and top as well. If you were to correct it, what specific grafts or technique would you use? Also, to what degree of symmetry can be restored, realistically? I've some pics that will hopefully help. Thank you!
