Newborns without ear canals can undergo reconstructive ear surgery. Newborns without ear canals are congenital malformations, which are caused by a variety of reasons during fetal development, either due to the lack of internal development of the ear, or due to the underdevelopment of the external auricle. Congenital auricular malformations should be treated as early as possible through surgery, including reconstruction of the ear canal and the auricle, to restore hearing and aesthetics. At the same time, the inner ear canal and the middle ear should be excluded to see if they are accompanied by congenital hypoplasia. During pregnancy, you should avoid exposure to harmful substances and undergo regular prenatal checkups to ensure the normal development of the fetus and to avoid malformations. If the fetus is affected and malformed during its development, you can wait for the birth of the fetus and choose the right time to undergo surgical treatments or terminate the pregnancy in time.
