Congenital Deafness

Congenital deafness is hearing loss present at birth or early infancy, due to genetic causes (nonsyndromic/syndromic) or intrauterine infections (rubella/CMV). Early detection prevents speech/language delay. Treatment: newborn hearing screening; hearing aids in infancy; cochlear implantation for severe-to-profound loss; speech/language rehabilitation; genetic counseling.

Common Symptoms

No response to sound; delayed speech; newborn-screen positive; by genetic/intrauterine-infection cause

Causes and Pathogenesis

Genetic cochlear defect or intrauterine infection damages the developing inner ear.

Treatment

Newborn screening; hearing aids; cochlear implant for profound loss; speech rehab; genetic counseling

Preventive Measures

Newborn hearing screening; rubella vaccination; genetic counseling.
