What is the cause of congenital deafness

First, the possibility of parents' heredity or inbreeding affecting their children's hearing. Children born to parents with congenital deafness are susceptible to the disease. But not all of the children are deaf. Although some parents have no deafness, if they are close relatives, the incidence of deafness is higher. In addition, there are auricle deformity, middle ear deformity, atresia of external auditory canal, hypoplasia of inner ear, or mental retardation.

Second: maternal rubella or other viral infections during pregnancy: may affect the hearing of the fetus. Especially when the mother suffers from the disease within three months of pregnancy, the fetal hearing loss is greater. The virus can invade the fetus through placenta and cause inner ear malformation.

Third: maternal use of harmful drugs during pregnancy, such as quinine, streptomycin, gentamicin and other ototoxic drugs through the placenta and circulation, resulting in fetal seventh cranial nerve poisoning, resulting in deafness.
