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

The septoplasty operation is specifically designed to improve airflow dynamics through the nose, not to correct a crooked nose.  The concaved appearance of the upper lateral cartilages on one side or the other is best addressed by harvesting residual septal cartilage and placement of a spreader graft on the concave and flail side that has herniated into the airway.  If the nose is cartilage depleted, then a small ear cartilage graft can be employed.  Any irregularities in the bone will be addressed through osteotomies to make the nose more symmetrical.  

Hello;

If the septum is still deviated, particularly if it's causing a nasal blockage, then the septum must be re-operated on. 

It sounds like it's needed because if it is distorting the lower portion or tip portion of the nose, then it does need to be corrected.  The revision rhinoplasty surgery will reveal that.

With respect to the outside of your nose: if straightening the septum straightens the outside, bravo! 

If it does not, however, another option may be, not necessarily a revision rhinoplasty, but rather  fillers instead to correct the depression, particularly on the right side. 

Only when the septum is straightened will the surgeon know exactly what it has, or has not, done.

My advice: have a very detailed re-consultation with the original surgeon.  Also, a second opinion is always worthwhile. 

Each surgeon must do a very thorough examination of the nose, particularly by anesthetizing and shrinking the inside so the existing architecture can be seen, as well as whatever tissues may have been removed in the original surgery. 

The more information a surgeon has, the better the choices that will be available to him and to you. 

Do not dismiss the filler option because it is very difficult often to get an ideally straight nose that is a bit crooked, and particularly if there is some depression of the bony or cartilaginous elements. 

Good luck!

Rhinoplasty can be safely performed after septoplasty but seek an experienced surgeon. An experienced Facial Plastic or Plastic Surgeon will be able to deal with the increased risks of revision septal surgery. The main limitation in performing rhinoplasty after prior septoplasty if finding adequate cartilage to rebuild the structural support of the nose. If this cannot be obtained from the nasal septum it can be readily obtained from the ear, cartilage portion of a rib or cadaveric donor tissue (my last choice due to some issues with warping and resorption). Fillers are a temporary solution and not without risk such as skin necrosis when used after prior nasal surgery. Further, fillers are camouflage. They are not a structural or permanent solution to your concerns.
