Rhinoplasty is performed after your facial bones and nasal cartilage have stopped growing, typically at about age 16 for females and 17 for males. However, this age can vary. You can tell whether your growth has slowed by noticing how quickly your height and shoe size are increasing. If you’re getting taller or your shoe size increases every six months, that’s a signal that you should wait on rhinoplasty. If you’re within an inch or two of your projected adult height, your bone and cartilage structure have probably matured enough to have the surgery.
