How to remove depressed scar on my nose bridge? (photos)

I want to get rid of this scar. When I was 5 years old I cut my nose with an aluminium plate two times in same place. My septum was deviated. I underwent septorhinoplasty at 26 years age. Now I am 34 years old. I am really worried about the scar. I checked with some local darmatologists. They have different suggestions like Skin grafting, PRP with CIT( collagen induced therapy), fat filler. I am confused. Kindly suggest me the best procedure to remove the scar on my nose bridge permanently.
