Revision rhinoplasty - do I need to make this better? (Photo)

I had a septo rhino plasty 12 years ago. Was really happy with the results. Unfortuately my 2 year old son head butted me by accident 6 weeks ago. No blood or black eyes. Only hurt at the time not after. I now have a bump on the left of my nose, and a long dent down the middle of my nose. It looks fine sideways on. Could this still resolve it self and what treatment do i need to make this better?
