Electronystagmography (ENG) in vertigo diagnosis
Electronystagmography (ENG) is a specialized test used to evaluate vestibular function and diagnose the underlying causes of vertigo. It measures involuntary eye movements (nystagmus) that occur in response to various stimuli, providing insight into the functioning of the vestibular system. Here’s an overview of how ENG is used in the diagnosis of vertigo:
Purpose of ENG
- Assessing Vestibular Function: ENG helps determine whether the vestibular system (part of the inner ear responsible for balance) is functioning properly.
- Identifying the Type of Vertigo: It can help distinguish between peripheral vestibular disorders (related to the inner ear) and central vestibular disorders (related to the brain).
Procedure
- Preparation: The patient is typically advised to avoid certain medications (e.g., sedatives, antihistamines) before the test, as they can affect results.
- Electrode Placement: Small electrodes are placed around the eyes to record eye movements.
- Testing: The patient undergoes a series of tests, which may include:
- Caloric Testing: Cold or warm water or air is introduced into the ear canal to stimulate the vestibular system. The resulting nystagmus is recorded and analyzed.
- Head Movement Tests: Rapid head movements are made to evaluate how well the vestibular system responds and how it affects eye movements.
- Positioning Tests: The patient may be positioned in different ways to provoke nystagmus and assess responses.
Interpretation of Results
- Positive Results: Abnormal nystagmus or asymmetrical responses between the two ears may indicate a vestibular disorder.
- Peripheral Causes: Conditions like Benign Paroxysmal Positional Vertigo (BPPV), vestibular neuritis, or Meniere’s disease may show characteristic patterns.
- Central Causes: Abnormalities in nystagmus that do not align with typical peripheral patterns may suggest central nervous system disorders (e.g., multiple sclerosis, tumors).
- Negative Results: Normal responses can help rule out vestibular dysfunction but may require further investigation if vertigo persists.
Advantages of ENG
- Non-invasive: The test is relatively safe and does not involve radiation.
- Detailed Information: ENG provides comprehensive data on eye movements and vestibular function, aiding in accurate diagnosis.
Limitations
- Subjectivity: Patient cooperation is essential, and some individuals may have difficulty maintaining focus during the test.
- Not Comprehensive: While useful, ENG is one of several tests that may be needed for a complete evaluation of vertigo.
Conclusion
ENG is a valuable tool in diagnosing the causes of vertigo. By evaluating eye movements in response to vestibular stimuli, it helps identify whether vertigo is due to peripheral or central vestibular issues, guiding further diagnostic and therapeutic strategies.
