Professor Wang Haibin from the Department of Plastic Surgery of the Second People's Hospital of Guangdong Province introduced that microtia must be treated surgically. Surgical correction mainly solves two problems: one is auricle reconstruction to solve external ear defect; Second, the ear canal and hearing reconstruction, so that children can hear. This deformity can be corrected by surgery, which can not only get a false ear, but also solve the hearing impairment.
