What is Otoacoustic emissions?

It is a quick, painless, and risk-free procedure to assess the inner ear’s response to sound, which represents an important advance in the identification of hearing problems in newborns and young children, as well as in adults who show cognitive abnormalities or several types of dementia or other neurological conditions.

The evaluation of otoacoustic emissions is performed by inserting a mini-probe similar to a small hearing aid in the baby’s or the child’s ear canal to record and measure their hearing capacity when exposed to a series of sound frequencies that will determine if there is any flaw that will prevent him or her from having an adequate development in terms of speech and language. 

This test, which does not require the child to demonstrate a behavioral reaction, can:

  • Detect hearing disorders that alter the path to the inner ear.
  • Identify the presence of sensorineural hearing problems.

However, it does not distinguish the types of conductive and sensorineural flaws, so it should not be used for diagnostic purposes without the combination of other tests that include a complete hearing test that allows an accurate diagnosis of the specific condition involved in each specific case.

At the Neurophysiology Clinic we are prepared to offer you the most advanced neurophysiological tests to diagnose the various pathologies that affect your nervous system, which represent a quantitative, reproducible, and generally non-invasive measure that enriches the neurological examination, providing an interaction platform and support in the diagnosis and treatment of neurologically affected patients.

The tests we perform include all the tools of a comprehensive neurophysiology service:

  • Electroencephalogram.
  • Electromyography.
  • Evoked potentials.
  • Outpatient polysomnography.
  • Hospital polysomnography.
  • Transcranial doppler.
  • Neuro-otology tests.
  • Otoacoustic emissions.
  • Intraoperative monitoring.
  • Magnetic stimulation.
