Thank you for your question and photograph.I would recommend scheduling a consultation with a board certified plastic surgeon who specializes in rhinoplasty so that they can perform a nasal examination on you and give you the best recommendations. From what I can tell from your photographs, you may benefit from a tip rhinoplasty which includes trimming the lower lateral cartilages and placing precision sutures to refine the tip and make it look more pleasing along with an alarplasty which is the technique that is commonly used for nostril reduction. This procedure consists of making an incision on the inside or outside of the nostrils then removing a specific amount of tissue to reduce the size and/or make more symmetrical. 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. 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
