Today, with the scientific and professional development of the medical team, birth defects can be screened early in the fetus and after birth.

Congenital deafness is a rare birth defect. There are many causes of congenital deafness, such as: Genetic problems, due to the mother's exposure to substances during pregnancy (such as medications, alcohol, tobacco, streptomycin poisoning...) that can damage the fetus's auditory nerve, or due to the newborn's head being damaged due to a difficult birth process, causing congenital deafness.
