The more unified view on the timing of surgery for external auricular deformity is that it is done during the child’s preschool years, usually around the age of 6. The main reasons for this are as follows: 1. The child’s psychological development begins when he is 4-5 years old, so if the auricular deformity is operated on before he goes to school, it will prevent the child from being ridiculed by other people after he goes to school and causing psychological disorders. 2. The length and size of the auricle of children between the ages of 5 and 10 years old are basically shaped, and may be only a little smaller compared to adults . If the surgery is performed at this time, it can achieve very good results and avoid doing it again in adulthood. The timing of surgery for auricular deformity in general depends on the patient’s personal situation, combined with the patient’s parents’ opinion and the severity of the patient’s lesion, and the specific time is usually before school age.
