20 Possible Causes for Absent or Abnormal Otoacoustic Emissions

  • Neuropathy

    At the same time, ABR responses are absent or very abnormal. This shows poor responses from the hearing nerve.[babyhearing.org] Emissions (OAEs) are often normal.[babyhearing.org] Auditory Brainstem Response (ABR) Otoacoustic Emission (OAEs) Behavioral Audiogram (if the child is older than 5 to 6 months of age) A characteristic finding with ANSD is that Otoacoustic[babyhearing.org]

  • Deafness

    Auditory brainstem potentials showed evidence of abnormal auditory pathway function beginning with the VIII nerve: the potentials were absent in nine patients and severely[doi.org] Auditory brainstem reflexes (middle ear muscles: crossed suppression of otoacoustic emissions) were absent in all of the tested patients.[doi.org] Evidence of normal cochlear outer hair cell function was provided by preservation of otoacoustic emissions and cochlear microphonics in all of the patients.[doi.org]

  • Sensorineural Hearing Loss
