Screening

Abnormal Finding

Loss of hearing sensitivity and acuity, from mild to profound, unilateral or bilateral

Tested By

Automated auditory brainstem response testing (AABR or ABR), sensitivity=100%, specificity=99.7% [Hall: 2004] or otoacoustic emission testing (OAE), sensitivity of 76.9%, specificity of 90% [Llanes: 2004]
AABR measurements reflect the function of the auditory system up through the brainstem, including the peripheral auditory system, the eighth nerve, and the brainstem auditory pathway. OAEs reflect the status of the peripheral system extending to the cochlear outer hair cells. In some clinics, OAE testing is performed first, with secondary AABR testing if the OAE is failed.

Description

The Joint Committee on Infant Hearing endorses early hearing detection and intervention for infants with hearing loss. The goal is to maximize linguistic competence and literacy development for children who are deaf or hard of hearing. Without early detection and opportunities for language development, children with hearing loss will fall behind their peers in communication, cognition, reading, and social-emotional development. [Joint: 2007]
  • Conductive hearing disorders involve outer and middle ear structures (congenital anomalies, otitis media, etc.).
  • Sensory hearing disorders involve the cochlea and inner ear structures (maternal and acquired infections).
  • Neural hearing disorders involve problems of the auditory nervous system (neoplasm and hypoxia, auditory neuropathy/dyssynchrony).
All infants should have a newborn hearing screening prior to 1 month of age. If immediate newborn screening is not possible (e.g., home birth, birth in a center not offering screening, or the infant is discharged before testing is completed), a referral should be made to a pediatric audiologist who can perform a screening within the first month of life. Repeat newborn hearing screening is recommended if an infant is readmitted to the hospital for sepsis, meningitis, or hyperbilirubinemia requiring exchange transfusion.
Infants admitted to the NICU for 5 days, or more are at increased risk for auditory neuropathy and should have both an AABR and OAE performed as part of their screening; in these patients, an OAE alone is insufficient.

Clinical Characteristics

With treatment starting by 6 months of age, children have improved language and speech skills.
Without treatment, children have impaired ability to communicate, decreased speech and language development, and problems with emotional and social development.

Incidence

For babies screened in the US for hearing loss, the incidence is about 1.7:1,000. It is higher in NICU populations. [National: 2019]

Inheritance

More than half of childhood hearing loss is genetic:
  • 77% recessive
  • 22% dominant
  • 1% X-linked
More than 400 genes have been identified that are associated with hearing loss. Approximately 70% of genetic sensorineural hearing loss is not associated with other known anomalies or abnormalities.

Primary Care Management

Next Steps After a Positive Screen

  • Contact the family and evaluate the infant for potential causes, including infections and syndromes.
  • Refer to an audiologist for repeat testing within 1 month and, if still positive, diagnostic testing to determine the type of hearing loss and possible causes.

Confirming the Diagnosis

Confirmatory testing for hearing loss and deafness should be completed by the time the infant is 3 months old. To confirm the diagnosis, work with:
