Routine
Uses:
• Screen infants in the newborn
nursery.
• Performs follow-up hearing
testing on infants from
the nursery screening, and at well-baby checks.
• Obtain objective hearing test
results from both ears of toddlers.
• Identify and monitor middle
ear pathology (e.g. otitis media).
• Assess cochlear function (without
the need for a behavioral response) following the insertion of pressureequalization
(PE) tubes.
• Monitor hearing in children
at-risk for progressive hearing loss.
• Screen patients of all ages
for cochlear (sensory) function so that appropriate recommendations
for
amplification can be made.
Differential
Diagnosis:
• Differentiate cochlear from
retrocochlear pathology when used in combination with auditory
brainstem
response (ABR).
• Observe changes in cochlear
function during episodes of Méniére’s Disease.
• Confirm suspected non-organic
hearing loss (malingering).
• Monitor the effects of ototoxic medications. OAEs will
often be abnormal before audiometric changes are noted.
• Detect early signs of hearing
loss from noise exposure (musicians, factory workers, others).
• Recognize auditory neuropathy.
The presence of normal OAEs and abnormal ABR
findings distinguishes
this low-incidence disorder.
