Hearing Loss- Health Encyclopedia and Reference |
 | | Common causes of conductive hearing loss are wax blocking the ear, a perforated eardrum, or fluid in the ears. |
 | | The causes of hearing loss may be congenital (present at birth) - genetic, use of ototoxic drugs during pregnancy, prenatal rubella in expectant mothers, infections during pregnancy, perinatal anoxia (fetal oxygen lack), or Rh blood disease. |
 | | Or, the cause may be acquired hearing loss - noise exposure, presbycusis, infections that affect the middle ear and inner ear such as mumps, measles and influenza, middle ear infections, ototoxicity (drugs that harm the inner ear), head injuries, benign tumors of the hearing nerve (acoustic neuroma), and cancer (rare). |
