The best age for otoplasty depends on the situation, generally the best age for otoplasty is around 6 years old, when it is technically and psychologically appropriate. around 6 years old the child’s ears have developed to 90-95% of their adult size, after which the size of the ears will not change significantly, so otoplasty around 6 years old will result in symmetrical ears, and the child will not have major changes as an adult. Before the age of 6, children are not particularly concerned about their abnormal ears, thus they do not cause serious psychological trauma and are not very cooperative with post-operative care, after the age of 6, children start to have a stronger will for surgical repair and can actively cooperate with the surgeon during and after surgery, and can compensate for ear deformities when they first become aware of them. This minimizes the psychological impact of the ear deformity on the child. In cases of bilateral microtia or aural agenesis, with external and middle ear deformities and hearing impairment, surgery is also advisable before school age, when not only the auricular deformity needs to be corrected, but also the hearing needs to be improved. This is not only for learning after school, but more importantly, for language development and for the physical and mental health of the child.
