Hypothesis
Can selective otolithic dysfunction be identified in patients presenting with acute spontaneous vertigo despite normal caloric and video-head impulse test results?
Conclusion
Selective otolithic dysfunction can present with acute vestibular syndrome and may be detected through thorough neurotologic evaluation and MRI.
Supporting Evidence
- Four patients with selective otolith dysfunction were identified despite normal results on caloric and video-HIT tests.
- Patients showed abnormal responses on vestibular-evoked myogenic potentials and subjective visual vertical tests.
- Gadolinium enhancements were found in the vestibule and vestibular nerves on MRI.
Takeaway
Some people who feel dizzy might have a problem with a part of their inner ear called the otolith, even if other tests seem normal.
Methodology
The study involved a retrospective review of medical records of patients with acute vestibular syndrome who underwent various neurotologic evaluations and MRI.
Limitations
The small sample size limits the generalizability of the findings.
Participant Demographics
Patients aged 32 to 74 years, including two males and two females.
