Can I straighten my crooked nose? How old would I have to be to get it straightened?

It's usually ok to consider having nose surgery to straighten it out around 14-17 years old. It sounds like you have quite a bit of functional problems with breathing from your nose so this aspect could be improved as well.You and your parents should consult with a surgeon who is experienced in correcting this type of problem. you can read more about crooked nose repair and see some before and after photos at my web reference link below.

Great question!  In general your nose keeps growing  all the way to the completion of puberty.  A lot of people might suggest that you wait until that time.  Given your functional problems with breathing it might make sense to do it early.   

Dear LilymeHow old do you have to be for rhinoplasty? Well, it depends on how severe your breathing problems are, as well as how much growth you have left as you get older. We repair children's noses with rhinoplasty at young ages, but most wait until your face has matured for a  cosmetic surgery.It is worth discussing with a surgeon and your parents, possibly checking the cause of your breathing problem with a small camera, and reviewing the best options for you.Best Wishes
