What can i do to fix this asymmetry? Is a rhinoplasty still possible? And what can be done about the crushed right nasal bone?

thank you for the photos  .  a profile view would be helpful.    the nose can be re operated on  but secondary surgeries are more complex , take longer and need a more skilled and experienced surgeon.. grafting may be needed.  an open method preferred.

a filler such as juvederm can give an idea as to how much it will help.   if this is adequate  a longer lasting filler such as radiesse can be used.

so ,  there are several options depending on your needs and budget

 

Provided you are now breating well, your chief complaint is aesthetic.  The nose must then be evaluated from the front, sides, and nostril view to determine which structures are causing and/or contributing to the crookedness, and any other existing aesthetic problems.  A surgical plan must be developed, and adjusted depending on intra-operative findings.

These can be challenging procedures, because all nasal structures are interconnected, and generally, complete mobilization of all deviated parts is required, modification to straighten everything out, and then secure the straightened parts to stabilize in the midline. 

The easy solution is injectables to fill your unilateral concavity.  Aquamid is ideal, or Radiesse.  The correction of nostril view or profile problems may be limited.  Since no profile or nostril view is submitted, I assume these are not huge issues for you.
