No breathing improvement after Surgery for deviated septum, 1 year post op - What can I do to improve breathing? (photos)

Nose was squishy. Had surgery 1 yr ago to fix deviated septum, valve collapse (rib graft), and re-build tip. No normal breathing improvement. The Tip, sides, front, are stiff like a muzzle. Columella seems wider near bottom post op making nostril holes smaller. Does wider columella reduce normal breathing? Can you thin it to increase space at entrance would it help? Risks? Would removing scar tissue from sidewalls (thick rib graft) help? How important is empty space? 55 yrs male.
