Do you feel any hearing loss? Electrocochleography is a test meant to find the electrical potential which you required.

Denoc Hearing Electrococheleography(ECOG or ECochG)

Electrocochleography is a test meant for recording electrical potentials generated in the inner ear (cochlea) and auditory nerveusing an electrode placed in the ear canal or tympanic membrane, in response to sound stimulation. It is predominantly used in the diagnosis, assessment and monitoring of Menier’s disease, and Endolymphatichydrops.

Clinical Procedure

  1. Patient is made to lie on a reclining chair or bed and remain still.
  1. The test involves placing few surface electrodes on the patient’s head.
  1. A tiny microphone and an earphone will then be inserted into the outer ear canal, so that it is close to the eardrum.
  1. The ear is stimulated with alternating polarity clicks
  1. The patient will be instructed to relax while they listen to a clicking sound.
  1. While the patient is listening to the clicking, Our audiologist will measure the ECochG response with the help of a computer that uses signal filtering and averaging to isolate neural activity from the cochlea.
  1. Our audiologist will collect several responses from the ear and will look for the presence of a largerwaveform which contains two components: the Summating Potential (SP) and the Action Potential (AP).
  1. Both of these waveforms are direct results of providing sound stimulation to the cochlea. A calculation of the SP/AP ratio is made. An increased SP/AP ratio can indicate excessive fluid pressure in the ear.

Patient Prior Preparation

  1. No major prior preparation is required for the patient.
  2. The patient should be relaxed for this test, since any tension or muscle movement can slow down the averaging process.
  3. No physical response from the patient is required for this test.

Average Testing Time

For an effective ECochG testing session it fetches around 45mins to 1hr for completion. Clinical reports will be provided immediately after test.
