Electronystagmogram (ENG)
ENG (Electronystagmography)
What To Think About
- At some centers, you cannot have an electronystagmogram if you have a pacemaker because the tool that measures eye movements can affect pacemaker function.
- Because an electronystagmogram cannot find some inner ear problems, a normal result does not mean an inner ear condition is not present.
- To check for hearing loss or tinnitus, other tests such as audiometry or a brain stem auditory evoked response (BAER) test may be done. If a tumor or stroke is suspected in a certain part of the brain, a CT scan or MRI may be used to confirm the diagnosis. For more information, see the medical tests Hearing Tests, CT Scan of the Head and Face, and Magnetic Resonance Imaging (MRI) of the Head.
