Adenoid faces generally appear in children and adolescents after the age of 3, but their stereotypes have no specific age. Adenoid face is a facial feature caused by adenoid hypertrophy, which will change with human growth and development. Once the adenoid face is formed, it can't recover on its own, and it needs drug intervention or other treatment methods to change it. Therefore, once the adenoid face appears, it generally needs professional medical treatment or plastic surgery to deal with it.
