Can my columella be corrected with dermal filler or will I need a second revision rhinoplasty? (photos)

I have had 2 rhinoplasties. After revision I am still not happy, and it looks like the doctor took too much columella to use it as a graft. Now I ended up with no columella and my nose looks so odd. Could it be corrected with filler or is it too risky? Or could a 2nd revision be possible to correct the nostrils and the columella? I am okay with the overall size now it is just the issues mentioned above bother me. Thank you for your advice in advance.
