Thank you for your question and photographs.A rhinoplasty would be the best procedure to correct the crooked appearance. You may also benefit from some tip refinement and an alarplasty to make the nostrils more symmetrical. Although, due to the crookedness of your nose, you may have some internal issues that need corrected so you may also need a septoplasty. I would recommend that you schedule a consultation with a board certified plastic surgeon who specializes in rhinoplasty to have a nasal examination performed and a review of your medical history to see what the best options are for you to achieve you cosmetic goals. In regards to cost, this varies based on surgeon and location. I can tell you that the RealSelf average cost for a rhinoplasty is between $7,000-$8,000 and if a septoplasty is needed, this should be covered by your insurance. Best of luck in your endeavors.Sincerely, James Fernau, MD, FACSBoard Certified ENTBoard Certified Plastic SurgeryMember of ASPS, ASAPS, ISAPS, The Rhinoplasty Society, AAFPRS, OTO/HNS, ASLMS, International Federation for Adipose Therapeutics & Science
