a 2 years old bb girl can do a rhinoplasty?
While young children occasionally require nasal surgery, it is typically carried out for functional reasons--nasal polyps, broken nose, complications associated with cleft lip, rare nasal tumors, and the like. Without knowing your child's history and your concerns, I would say that elective cosmetic surgery in a 2-year-old child is not appropriate. Elective nasal surgery such as cosmetic rhinoplasty can be offered to adolescents at the youngest; the ideal young person is near to or has stopped growing and is mature enough to understand the risks and benefits of surgery, post-operative care and healing, and the importance of compliance in treatment.
Generally we recommend that patients wait until they're in their late teens prior to considering nasal surgery. Ideally we wait until the nose finishes growing so that the end result is more predictable.
