Videonystagmography for vertigo
Videonystagmography, often called VNG, helps assess eye-movement patterns that reflect balance-system function. It may be advised when recurrent vertigo needs clearer evaluation.
- Recurrent vertigo, imbalance or dizziness needing more detailed balance assessment
- Eye-movement based balance testing advised after ENT evaluation
- Inner-ear vertigo pattern suspected but diagnosis still needs confirmation
What videonystagmography looks at
VNG records and analyses eye movements because the balance organs and eye movement pathways work together. Abnormal patterns can help point toward an inner-ear balance issue or clarify the dizziness pattern.
This is useful when the history suggests vertigo but the exact cause or side is not yet clear from symptoms alone.
When this test is usually considered
VNG may be advised when vertigo keeps returning, when position-related dizziness is not straightforward, or when the doctor needs more objective balance information before guiding treatment.
It may be combined with other balance assessment steps depending on symptoms, hearing findings and whether BPPV, unilateral vestibular weakness or another inner-ear disorder is suspected.
What patients should know before testing
The test is generally planned, explained and tailored to the symptom pattern. Some parts may briefly reproduce dizziness because the purpose is to study the balance response safely under observation.
Preparation advice can vary, so patients should confirm instructions directly before the visit instead of assuming all dizziness tests are identical.
How the result helps treatment
The report helps the ENT doctor decide whether the pattern supports inner-ear vertigo, whether more focused positional treatment is reasonable, or whether another pathway should be considered.
This helps avoid vague trial-and-error treatment when a more targeted balance plan is possible.

Frequently asked questions
Is VNG needed for every vertigo patient?
No. It is advised only when it adds useful information beyond the history and examination.
Can the test make me feel dizzy during the procedure?
Some parts may briefly provoke dizziness because the balance response is being studied, but the test is done in a controlled setting.
Does VNG replace all other balance tests?
Not always. It may be used alongside positional assessment, caloric testing or other balance evaluation depending on the case.
