Over 1 year Post Septo-rhinoplasty - Can this be fixed with only a scar revision, or would a cartilage graft be needed? (Photos)

I am over 1 year Post Op (Septo-rhinoplasty) and as you can see I am left with a very bad scar along my columella. There are also some symmetry issues with the alignment of the columella and inner nostrils. This can be seen from the 3/4 view as well as the profile. It looks as if the "upper" part of the columella is slightly lower than the "bottom" part of the columella, so the two sections do not sit flush. Can this be fixed with just a simple scar revision, or would cartilage need to be placed in the lower section of the columella? Additionally, I would greatly appreciate if anyone could tell me if they have seen this issue before. Kind regards, M
