Professor Wang Haibin of the Plastic Surgery Department of Guangdong Second People's Hospital said that there is a certain incidence of ear defects. The most serious ear deformity is microtia, or ear development disability. For these ear deformities or defects, ear reconstruction is required. Ear reconstruction surgery is relatively mature. It is generally recommended to perform auricle reconstruction surgery at the age of six to seven years old to restore the shape of the auricle.
