Oto Acoustic Emission (OAE) is a screening (early detection) or hearing test of newborns that capture emissions in the cochlea. If the OAE test states that PASS and the baby have no risk factors, then the baby will have a further hearing diagnostic at 1 to 3 years of age. If the results of OAE are known to have nerve deafness, then the baby must immediately undergo hearing rehabilitation. This is done as early as possible using a hearing aid (ABD) no later than 6 months or cochlear implant. The causes of hearing loss in newborns vary greatly, ranging from TORCHS infection during pregnancy to a family history of nerve deafness from birth. Hearing loss in infants can also be caused by anatomic abnormalities or brain infections.
Why Need an Acoustic Rural Emission (OAE) Test?
Hearing loss in infants and children is difficult to know from the beginning. Hearing loss in infants can cause speech, language, cognitive, problems s emotional and emotional. The critical period of hearing and speech development begins in the first 6 months of life and continues until the age of 2 years. The newborn hearing test is done after the baby is born or no later than 1 month after birth. Hearing test results can be used as a further examination for the diagnosis of hearing loss in infants aged 3 months.
Does the Acoustic Emission Oto Test Need Follow Up?
After hearing tests on newborns with Oto Acoustic Emission (OAE) and automated Brain Evoked Response Auditory (BERA), 3-month-old babies should be examined further if necessary such as a diagnosis of hearing in the external ear by otoscopy, middle ear with tympanometry, examination repeated OAE for the ear nerve, as well as a repeat examination of the BER for the auditory central nerve in the brain.
If all examination results show normal values, monitoring of the development of speech in the baby will then be followed by monitoring hearing function every 3 to 6 months until the age of 3 years. However, if the results are abnormal, it should be followed by checking tone burst bursts ASA or ASSR and high frequency tympanometry.
If there are known nerve deafness, then immediately do hearing habilitation as early as possible and you should install a hearing aid no later than 6 months of age or do cochlear implants.
