Delving Deeper: Understanding Electrocochleography (ECochG) and Its Role at Baranagar Speech & Hearing Clinic

At Baranagar Speech & Hearing Clinic, we are committed to utilizing cutting-edge diagnostic techniques to provide the highest standard of care for our patients. One such advanced procedure that we offer is Electrocochleography (ECochG), a valuable tool in the assessment of inner ear conditions. In this comprehensive guide, we'll explore the intricacies of ECochG and its significance in diagnosing excessive fluid pressure within the cochlea.

Understanding Electrocochleography (ECochG):

Electrocochleography, or ECochG, is a specialized diagnostic test used to evaluate the electrical activity generated by the cochlea in response to sound stimuli. Unlike traditional hearing tests that focus solely on measuring auditory thresholds, ECochG provides valuable insights into the function of the inner ear, particularly in cases where there may be abnormalities such as excessive fluid pressure.

How ECochG Works:

During an ECochG procedure, electrodes are placed on the scalp or within the ear canal to detect electrical signals generated by the cochlea in response to sound. The patient is exposed to a series of auditory stimuli, ranging from clicks to tones of varying frequencies and intensities. By analyzing the amplitude and latency of the electrical responses, clinicians can assess the health and function of the cochlea.

Indications for ECochG:

ECochG is most commonly utilized to diagnose conditions such as Ménière's disease, a disorder of the inner ear characterized by episodes of vertigo, tinnitus, and fluctuating hearing loss. One of the hallmark features of Ménière's disease is the presence of excessive fluid pressure within the cochlea, which can be detected through abnormalities in the ECochG waveform.

Additionally, ECochG may be recommended in cases of suspected endolymphatic hydrops, a condition characterized by the accumulation of fluid in the inner ear. By accurately identifying the presence of fluid pressure abnormalities, ECochG plays a crucial role in guiding treatment decisions and improving outcomes for patients with inner ear disorders.

The ECochG Procedure at Baranagar Speech & Hearing Clinic:

At Baranagar Speech & Hearing Clinic, our experienced audiologists are trained in performing ECochG with precision and expertise. We utilize state-of-the-art equipment and adhere to strict protocols to ensure the accuracy and reliability of test results.

Prior to the procedure, our team will conduct a comprehensive evaluation to determine the appropriateness of ECochG for each individual patient. During the test, we prioritize patient comfort and safety, providing clear instructions and addressing any concerns or questions that may arise.

Once the ECochG data has been collected, our audiologists will carefully analyze the results, interpreting the findings in the context of the patient's overall clinical presentation. We believe in a collaborative approach to patient care, and we will work closely with referring physicians and other healthcare providers to develop a customized treatment plan tailored to each patient's unique needs.


In conclusion, Electrocochleography (ECochG) is a valuable diagnostic tool for evaluating inner ear function, particularly in cases where there may be abnormalities such as excessive fluid pressure. At Baranagar Speech & Hearing Clinic, we are proud to offer ECochG as part of our comprehensive range of services, providing patients with accurate diagnosis and personalized care. If you or a loved one are experiencing symptoms of inner ear disorders, we encourage you to schedule a consultation with our experienced team to learn more about how ECochG can help guide your treatment journey towards better hearing and overall wellness.
