If a newborn has a deformed ear, it is mostly due to an intrauterine infection. If the child gets infected with viruses like rubella virus, herpes virus and other infections in the mother’s womb. The child then develops abnormalities in development, which can lead to auricular deformities. Common ear deformities include microtia or unusually shaped ears. These conditions are specific manifestations of auricular deformities. In addition, children often have other deformities, such as polydactyly or congenital heart disease. In this case, parents will have to tailor the treatment to the child’s specific condition. For example, if the child has cytomegalovirus infection, antiviral drugs such as ganciclovir can be administered promptly. In addition, if the child’s ear deformity is very serious, it can be treated with surgery in plastic surgery.
