Why is my nose squint again 9 months after Septorhinoplasty? Is this my surgeon's fault? (Photo)

 Yes your nose still appears crooked from a deviated septum . Very often the septum wants to pull back to the way it was. Either have your original surgeon do the revision or get a second opinion from a revision rhinoplasty surgeon.

Yes, your nose is still deviated.  You should consider a revision rhinoplasty. You also need some additional work on the tip.  At least you are showing improvement. 

Yes your septum is still displaced but better. The septal cartilage often wants to bend back to its original position.  It can be tricky, and you likely could need another revision.

Overall a very acceptable result. Either revision of fillers could improve it. Best to ask your surgeon for an opinion... 

There are a variety of issues to consider.  First of all, at 9 months after surgery, while you are not completely healed, it is unlikely that you will see significant changes  as more time goes by.  Yes, your nose remains crooked and could benefit from a revision.  As revision surgery, by definition, is a bit more complex than initial surgery, please seek consultation with a surgeon who has a lot of experience with revision rhinoplasty.  Your problem is quite common, so I would expect that you could get improvement with further surgery.
