Who Performs Electrocochleography?

Electrocochleography is performed by highly specialized medical and audiology professionals. Specifically, the test is conducted by an otologist or an audiologist who possesses specialized training in this diagnostic procedure.

Key Professionals Involved

The accurate administration and interpretation of Electrocochleography (EcochG) require specific expertise. Here’s a breakdown of the professionals who perform this test:

• Otologist:

  • An otologist is a medical doctor who specializes in diseases and disorders of the ear. They often have surgical training and focus on conditions affecting hearing, balance, and the temporal bone.
  • Their role in performing EcochG often involves diagnostic assessment related to complex ear conditions or the monitoring of inner ear and auditory nerve function during surgical procedures.

• Audiologist:

  • An audiologist is a healthcare professional who specializes in identifying, diagnosing, treating, and monitoring disorders of the auditory and vestibular systems (hearing and balance).
  • Audiologists perform EcochG primarily for diagnostic purposes, such as evaluating specific types of hearing loss or balance disorders, particularly those related to inner ear fluid pressure.

The Importance of Specialized Training

Both otologists and audiologists who perform Electrocochleography must undergo specialized training. This training is crucial due to the intricate nature of the inner ear, the technical demands of the test, and the precise interpretation of the electrical responses measured. The procedure involves placing electrodes near or in the ear to record the electrical potentials generated by the cochlea (inner ear) and auditory nerve in response to sound.

Purpose of Electrocochleography

This specialized test is utilized for several important diagnostic and monitoring purposes related to inner ear health:

• Detection of Elevated Inner Ear Pressure: One primary use is to detect elevated inner ear pressure, a condition often referred to as endolymphatic hydrops. This condition is associated with symptoms such as fluctuating hearing loss, tinnitus, and vertigo, commonly seen in Meniere's disease.
• Intraoperative Monitoring: It is also used for the testing and monitoring of inner ear and auditory nerve function during surgery. This helps surgeons protect these delicate structures and ensure their integrity throughout the procedure.
