Can I use apple cider vinegar on my nose 12 days after rhinoplasty/septoplasty?

Dear ahansen5,That should be a fine toner to use at 12 days after rhinoplasty. You should discuss this with your surgeon to be sure that they do not have any concerns.

Dear ahansen5,every plastic surgeon has his own postoperative protocol which he recommends to his patients. I would suggest you to discuss this with your plastic surgeon.Daniel Barrett, MD, MHA, MS

It should be no problem to use your toner on your nose after the Rhinoplasty.  However, if you do have external sutures you should make sure to avoid these areas.  I would also consult with your PS on what their recommendations are.
