Dear Anna, I have operated on 15 years olds for Rhinoplasty (nose job), but in addition to their desire for surgery, they had to obtain the consent of their two parents and pediatrician. Every surgery is stressful and more so with nose job , because you can't hide it. So, we need to make sure that your daughter is mature enough to undergo the procedure and understand surgery and the healing process. Ward of caution. Not all results are the same , because experience, skills and aesthetic eye are critical for good outcome. So, do your due diligence and choose wisely. Always consult with experience board certified plastic surgeons who operate in accredited surgery center for your daughter safety. Check the before and after pictures, to make sure that they are numerous, consistent and attractive. Best of luck, Dr Widder
