Abstract PDF: Ramsay Hunt syndrome occurs when the varicella zoster virus reactivates. Classic findings include the triad of facial paralysis, otic pain and herpetic lesions due to the pathogenesis associated with anterograde axonal reactivation of the varicella zoster virus in the geniculate ganglion. In addition to the classic triad, rare features such as a central type of vestibular function test may be observed due to the retrograde spread of the varicella zoster virus from the geniculate ganglion into the brain stem, including involvement of the vestibular nucleus. We present a case of Ramsay Hunt syndrome in a 57-year-old male patients, manifesting not only the typical triad of symptoms but also the unique features associated with brain stem involvement. This presented as direction-changing gaze-evoked nystagmus and a decrease in gain on both sides on video head impulse test. And brain magnetic resonance imaging showed a lesion in the vestibular nucleus of the brain stem.

Abstract PDF: Facial palsy can be caused by central and peripheral causes, and it can also be caused by brain tumors or infarction. A 59-year-old male, who lost his right hearing 13 years ago due to Ramsay Hunt syndrome, visited our hospital with facial palsy and dizziness. Initial brain diffusion-weighted magnetic resonance imaging (MRI) showed no abnormal findings, and recurrent Ramsay Hunt syndrome or a neoplastic lesion in the internal auditory canal was suspected. After hospitalization, the patient was administered high-dose steroids, and the videonystagmography showed direction-changing gaze-induced nystagmus, so a brain MRI reexamination was scheduled. While waiting for MRI, the patient complained of neurological symptoms such as diplopia, and right lower pontine infarction was diagnosed on MRI. The patient was transferred to the neurologic department and was discharged on the 10th day after conservative treatment. During the 1-year follow-up, pontine infarction did not recur, and neurological symptoms such as facial palsy gradually improved.

Abstract PDF

Objectives
This study was performed to investigate the correlation between subjective residual dizziness and objective postural imbalance after successful canalith repositioning procedure (CRP) in benign paroxysmal positional vertigo (BPPV) by using questionnaires and modified Clinical Test of Sensory Integration and Balance (mCTSIB).
Methods
A total of 31 patients with BPPV were included prospectively in the study. All included patients were successfully treated after initial CRP and their symptoms and nystagmus disappeared. Two weeks after CRP, all patients were asked to fill out the questionnaire including both Dizziness Handicap Inventory (DHI) and visual analog scale (VAS). We also conducted mCTSIB 2 weeks after CRP. We divided patients into two groups according to VAS: RD (residual dizziness) group, VAS＞0; non-RD group, VAS=0. We compared age, number of CRP, rates associated with three semicircular canals, DHI score and mCTSIB results between two groups. In addition, we analyzed the correlation between DHI score and mCTSIB results.
Results
There were no significant differences in age, number of CRP, and rates associated with three semicircular canals between the two groups. RD group showed significantly higher DHI score and abnormal mCTSIB results than the non-RD group (p＜0.05). DHI score and the number of abnormal mCTSIB showed a statistically significant correlation.
Conclusions
We demonstrated the correlation between DHI score and mCTSIB after successful CRP for BPPV. It also represents that subjective residual dizziness is correlated with objective postural imbalance even after successful CRP. Therefore, mCTSIB would be a useful test to evaluate both residual dizziness and postural imbalance after CRP in BPPV.

Abstract PDF

Recently with the introduction of video head impulse test (vHIT), it can be easily performed quantitative and objective measurement of vestibulo-ocular reflex (VOR). vHIT has been used as a clinical vestibular function test that can individually evaluate the function of each semicircular canal. Loss of VOR gain and corrective catch-up saccades that occur during the vHIT usually indicate peripheral vestibular hypofunction, whereas in acute vestibular syndrome, normal vHIT should prompt a search for a central lesion. In this study, we will examine the principle of vHIT and its interpretation, and explain its clinical application in peripheral and central vestibulopathy. In addition, we will compare the caloric test and the differences, and review the most recently introduced suppression head impulse paradigm test.

Abstract PDF

Objective: Cervical vestibular evoked myogenic potential (cVEMP) is thought to be assessing the function of the saccule and inferior vestibular nerve. Therefore, cVEMP indirectly reflects the function of the posterior semicircular canal. Recently, the video head impulse test (vHIT) is considered as useful clinical tool to detect each semicircular canal dysfunction. Goal of this study was to evaluate and compare the results of cVEMP with posterior canal plane of vHIT (p-vHIT).
Methods
Retrospectively, we compared the results of cVEMP with p-vHIT in 43 patients who visited with dizziness. We analyzed the inter-test agreement of cVEMP with p-vHIT.
Results
Positive asymmetry of cVEMP was present in 37.2% (16/43), and no responses of both ears were identified in 16.3% (7/43). In p-vHIT analysis, unilateral positive was 27.9% (12/43), bilateral positive was 11.6% (5/43) and negative in both sides was 60.5% (26/43). The inter-test agreement between cVEMP and p-vHIT was 75.8% (25/33) as we considered even in lesion side. And, Fleiss’s kappa value showed a fair to good agreement (kappa value=0.559). In bilateral no response group (7 patients) in cVEMP, variable additional information could be obtained using p-vHIT.
Conclusion
cVEMP and p-vHIT showed relatively lower inter-test agreement than expected. But, p-vHIT could be easily performed, and give additional information for differential diagnosis.
