AbstractAbstract PDF
Objectives
This study is performed to evaluate the effect of early steroid treatment within 24 hours of onset in acute vestibular neuritis (AVN).
Methods
We performed a retrospective case-control study with 46 patients with AVN. Video head impulse test paradigm (HIMP) and suppression HIMP were performed, and dizziness handicap index (DHI) was determined at initial; all tests were repeated at 1 month. Patients were divided into two groups depending on whether they were treated with steroids (group S, n=21) or not (group n-S, n=25).
Results
There was no significant difference in age, sex, and side between the two groups. In HIMP, group S showed a significantly lower occurrence of overt corrective saccade (CS) (p=0.034) and lower peak velocity of overt CS (p=0.020) than group n-S at 1 month. In addition, the DHI score at 1 month was significantly lower in group S than in group n-S (p=0.040). In correlation analysis between subjective symptom and objective parameters, the DHI score showed a significant correlation with the occurrence of overt CS (p=0.028) and PR score (p=0.006) at 1 month.
Conclusions
Early steroid treatment in AVN would be helpful for relieving symptoms and the improvement of vestibular ocular reflex function in the recovery phase.

Objectives
Big data analytics in healthcare research have gained momentum, offering unprecedented opportunities to investigate complex medical conditions like acute vestibular neuritis (AVN). However, an inappropriate definition can introduce bias and inaccuracies into prevalence estimation, making the results unreliable and hindering cross-study comparisons. The Health Insurance data in South Korea will be used to create a robust operational definition for AVN.
Methods
The study utilized the National Patients Sample dataset from the Health Insurance Review and Assessment Service (HIRA) of the Republic of Korea. The operational definition of AVN was defined using the HIRA data, which includes specific codes for diagnosis, testing, and medications. The revised categorization scheme for AVN was presented as case 1 through case 5, with criteria for each category.
Results
The optimal conditions are deemed to be those that encompass the outcomes of both case 5 and case 1-1, encompassing all conditions. The study also provided prevalence estimates for subgroups based on demographic factors (age, sex), and found a consistent pattern throughout all years, sex, and age.
Conclusions
The study analyzed the prevalence of AVN in case 1 and case 5, which were similar to the reference prevalence of 3.5 per 100,000 people reported in other countries. The study’s results are encouraging for several reasons, including the validity of the operational definitions used, and the agreement between the study’s prevalence estimates and the reference prevalence. The operational definition in statistics, in the context of big data, serves as a precise and standardized criterion.

AbstractAbstract PDF
Coronavirus disease 2019 (COVID-19) spread rapidly and was declared a pandemic. In this situation, vaccination for COVID-19 is important and has been prompted in many countries. However, a number of adverse events have been reported for the Pfizer, Moderna, and AstraZeneca vaccines. Otolaryngologic adverse events after COVID-19 vaccination were reported, including several cases of sudden sensorineural hearing loss. Vestibular neuritis (VN) is an acute vestibular syndrome that causes acute and spontaneous vertigo due to unilateral vestibular deafferentiation, leading to nausea or vomiting and unsteadiness that can last from days to weeks. Neurotropism for the cochleovestibular nerve, immunoglobulin G mediated immune off-target reaction, and reactivation of latent viruses are hypothesized to be etiologies. Herein, the case of a 49-year-old female who developed VN after COVID-19 vaccination is presented. Although the association between VN and COVID-19 vaccination remains unclear, clinicians should be aware that VN may occur as an adverse event of COVID-19 vaccination.

AbstractAbstract PDF
Paraneoplastic cerebellar degeneration is a rare neurological manifestation of nonmetastatic malignancy. Its usual manifestation is subacute to chronic dizziness, gait ataxia, and dysarthria. There have been only a few cases of paraneoplastic cerebellar degeneration with acute presentation. This study describes a patient with paraneoplastic cerebellar degeneration, who presented acute vestibular syndrome and then episodically developed horizontal gaze-evoked nystagmus and gait ataxia.

AbstractAbstract PDF
Acute vestibular syndrome refers to the rapid onset of vertigo, nausea, vomiting, and unsteady gait. Acute unilateral vestibular neuritis is the most common cause of acute vestibular syndrome. However, vascular lesions involving the brainstem and cerebellum also produce acute vestibular syndrome even without other neurologic deficits. The vestibular nucleus or nucleus prepositus hypoglossi in the dorsal portion of the brainstem, cerebellar structures including flocculus, tonsil, and nodulus, and cerebellar peduncle can produce isolated vertigo and imbalance when damaged. Early recognition of the pseudo-vestibular neuritis of the vascular etiology is warranted for clinicians.

AbstractAbstract PDF
Vast majority of triggering factors preceding vestibular neuritis (VN) are unknown, although many cases are associated with viral infection. A 55-year-old woman was bitten by a viper on her right hand, and she was treated with antivenom at the primary clinic. Three days later, acute persistent vertigo was developed. Neuro-otologic examinations revealed spontaneous left-beating nystagmus and abnormal head impulse test in the right side. Taken together with negative result of brain magnetic resonance imaging, she was diagnosed with a right VN. Various neurological complications such as paralysis, optic neuritis, and stroke can occur after snakebite envenoming. In this case, given the time interval between snakebite and development of dizziness, snakebite envenoming might be a possible predisposing factor of VN as a proinflammatory condition rather than a direct cause of VN. Furthermore, the VN of this case was probably caused by late adverse reactions after antivenom administration. Since about 10% of the snake-bitten patients have complained dizziness, detailed neuro-otologic evaluations may lead to a proper understanding of pathomechanism and a correct diagnosis.

AbstractAbstract PDF
Objectives
The aim of this paper was to determine if a correlation exists between video head impulse test (vHIT) and electronystagmography with caloric test (ENG). More specifically, comparison of covert and overt value from vHIT test with cold and warm stimulation value from ENG test.
Methods
Retrospective study of our single institue from the period of January 2015 to January 2017 enrolled 91 patients. Patients were divided into 3 groups by their diagnosis of either vestibular neuritis (VN), Meniere disease, or sudden sensorineural loss with vertigo accordingly. Each of the patients’ both ENG and vHIT data were recorded and parameters were evaluated.
Results
VN group was the only group to show a significant correlation between canal paresis (CP) with covert and overt saccades. Further analysis was done in the VN group and result showed covert saccade showing a larger area under the receiver operation characteristic curve value (0.77) compared to overt saccades (0.70), implying that covert saccade is a more accurate parameter for the prediction of the CP value. Furthermore, a positive correlation was seen between the gain value and the cold caloric stimulation value as well as between warm caloric stimulation value.
Conclusions
The value of our study lies in the fact that we have attempted to find a correlation between different parameters of 2 different vestibular tests. We concluded that the evaluation of overt nystagmus by the bedside head thrust test is inappropriate for predicting CP, and a vHIT is required to accurately evaluate vestibular function.

AbstractAbstract PDFSupplementary Material
Down-beat nystagmus in peripheral vestibulopathy may rarely occur in selective involvement of inferior division. Diagnosis of isolated inferior vestibular neuritis is based on torsional down-beating spontaneous nystagmus, abnormal head-impulse test for the posterior semicircular canal, and abnormal cervical vestibular evoked myogenic potentials (cVEMPs) with normal bithermal caloric tests and ocular vestibular evoked myogenic potentials (oVEMPs). Herein we report a 50-year-old male patient with spontaneous down-beat nystagmus who demonstrated vestibular dysfunction involving only the posterior semicircular canal. The patient showed normal results in the bithermal caloric test, the oVEMPs and cVEMPs test. Video head impulse test showed decreased gain and corrective saccades only in the posterior semicircular canal. This case is significant in showing that peripheral dizziness with spontaneous down-beating nystagmus can occur as a result of an abnormality involving only a single semicircular canal.

AbstractAbstract PDF
Objectives
Despite patients with dizziness were reported of revealing gait problems, there is still lack of objective quantitative measurement of gait patterns of peripheral vestibular disorders. To demonstrate gait variability in acute unilateral peripheral vestibular deficit, we evaluated the differences in gait patterns between vestibular neuritis (VN) patients and healthy subjects by the use of shoe-type inertial measurement unit (IMU) with sensors mounted.
Methods
Between April 2017 and January 2019, 30 patients diagnosed with unilateral peripheral vestibular deficit presumed to be caused by VN were enrolled in this study. The shoe-type IMU was used to analysis subjects. We assessed gait speed, cadence, stride length, stance phase, normalized stride length, normalized step length, phase coordination index and gait asymmetry of data from shoe-type IMU sensors with the walking protocol. We tested 30 healthy volunteers as control group.
Results
We identified spatiotemporal parameters of human gait. The gait speed of patients with VN was decreased to 3.82±0.8 compared to 4.93±1.08 in control group. In addition, there were differences in normalized stride length, normalized gait speed and related gait parameters, when comparing VN group and control group.
Conclusion
Gait analysis by the use of shoe-type IMU could provide important information regarding vestibular pathophysiology in patients with VN. Gait performance tests can examine gait variability quantitatively. It will be taken into consideration as a vestibular function test for patients with vertigo.

AbstractAbstract PDF
Acute vestibular neuritis (VN) is characterized by acute/subacute vertigo with spontaneous nystagmus and unilateral loss of semicircular canal function. Vestibular system in human is represented in the brain bilaterally with functional asymmetries of the right hemispheric dominance in the right handers. Spatial working memory entails the ability to keep spatial information active in working memory over a short period of time which is also known as the right hemispheric dominance. Three patients (patient 1, 32-year-old female; patient 2, 18-year-old male; patient 3, 63-year-old male) suffered from acute onset of severe vertigo, nausea and vomiting. Patients 1 and 2’s examination revealed VN on the right side showing spontaneous left beating nystagmus and impaired vestibular ocular reflex on the right side in video head-impulse and caloric tests. Patient 3’s finding was fit for VN on the left side. We also evaluated visuospatial memory function with the block design test in these 3 VN patients which discovered lower scores in patients 1 and 2 and the average level in patient 3 compare to those of healthy controls. Follow-up block design test after resolved symptoms showed within normal range in both patients. Our cases suggest that the patients with unilateral peripheral vestibulopathy may have an asymmetrical effect on the higher vestibular cognitive function. The right VN can be associated with transient visuospatial memory dysfunction. These findings add the evidence of significant right hemispheric dominance for vestibular and visuospatial structures in the right-handed subjects, and of predominant dysfunction in the hemisphere ipsilateral to the peripheral lesion side.

AbstractAbstract PDF
Objectives
In vestibular neuritis (VN), the lesion preferentially affects the superior vestibular nerve because of the anatomic arrangement. It is well known that VN patients have a higher score of metabolic syndrome or a higher incidence of vertebral artery hypoplasia than controls. However, it is unclear whether the frequency of cardiovascular risk factors can affect the selective involvement of the branch of the vestibular nerve. Thus, we investigated the influence of cardiovascular risk factors on the development of total- or divisional VN. Methods: 61 patients with VN were enrolled. Video head impulse tests and caloric tests were performed to determine which vestibular divisionswere affected. The patients were divided into divisional-VN (superior or inferior) and total-VN groups. Statistical analysis of the frequency of cardiovascular risk factors was performed only in superior and total VN groups because the number of inferior VN patients was too small to be statistically analyzed. Results: Nineteen (31.1%) patients were classified as the total-VN group. In the divisional-VN group (42 patients, 65.6%), 40 were superior VN. The frequency of cardiovascular risk factors are not significantly different in superior VN and total-VN groups (All patients 50/61 [82.0%], superior-VN 36/40 [90.0%], total-VN 13/19 [68.4%]). The frequency of having more than one cardiovascular risk factor was slightly higher in the superior VN group, (13 [68.4%] vs. 36 [90.0%], p=0.062) but did not show any significant difference. Conclusions: The number of cardiovascular risk factors did not differ in superior VN patients compared to total VN patients.

AbstractAbstract PDF
Acute vestibular neuritis is the disorder characterized by acute, spontaneous vertigo with the unilateral vestibular loss. Reactivation of herpes simplex virus is considered as its cause. Its management consists of symptomatic therapy in the acute phase and following rehabilitation exercise to improve central compensation. The differential diagnosis should include central vestibular disorders mimicking peripheral vertigo. Ramsay-Hunt syndrome, which defined as a herpes zoster oticus with facial paresis, is also a disorder frequently accompanied with vestibular deficit. Combination therapy of acyclovir and corticosteroid is recommended for the treatment. In this review, diagnosis and management of the two disorders are described.

AbstractAbstract PDF
Vestibular neuritis is characterized by rapid onset of vertigo, nausea and vomiting without neurological symptoms or signs, but central vestibular lesions can cause similar symptoms and signs. A 66-year-old woman previously diagnosed with ovarian cancer initially presented with vertigo. The patient had typical symptoms and signs of vestibular neuritis. As time proceeded, the patient presented with bilateral catch-up saccade and the symptoms and signs of cerebellar dysfunction. Magnetic resonance image and computed tomography scan showed brain metastasis surrounded by edematous lesion. We report an ovarian cancer patient with metastasis mimicking vestibular neuritis with a review of related literature.

AbstractAbstract PDF
Background and Objectives: Vestibular neuritis predominantly affects the superior branch of the vestibular nerve, resulting in vertigo. Acute viral labyrinthitis occurs when an infection affects both vestibulo-cochlear nerve and labyrinth, resulting in hearing changes as well as vertigo. The purpose of study is to identify there is a difference of cervical vestibular evoked myogenic potentials (cVEMP) and ocular VEMP (oVEMP) in patients with vestibular neuritis and acute viral labyrinthitis. Materials and Methods: cVEMP and oVEMP tests using 500-Hz tone-burst stimuli were performed on patients with vestibular neuritis and acute viral labyrinthitis. Pure tone audiometry, caloric test and subjective visual vertical (SVV) were performed in all patients. We compared the VEMP results, SVV, caloric test in patients with vestibular neuritis and acute viral labyrinthitis. Results: Abnormal cVEMP responses were detected in 2 (20%) patients with vestibular neuritis and 5 (100%) patients with labyrinthitis. Abnormal oVEMP responses were detected in 9 patients (90%) with vestibular neuritis and 5 (100%) patients with labyrinthitis. oVEMP abnormalities is correlated with caloric test and subjective visual vertical in patients with vestibular neuritis and labyrinthits. Conclusion: Our results shows that the response of cVEMP and oVEMP between patients with vestibular neuritis and acute viral labyrinthitis is different. We can infer that oVEMP response to air-conducted sound is different vestibular origin compared to cVEMP and may originate from utricle.
