OBJECTIVES: Over the last decades, numerous studies on the effect of vestibular rehabilitation (VR) have been reported in western countries, but there has been no report about real experiences of customized VR in Korea. The aim of this study was to analyze of the efficacy, compliance and satisfaction in patients with acute and chronic dizziness. METHODS: Patients with dizziness were treated with a customized VR at least 4 weeks. Subjects were assessed before and after at least 4 weeks of customized VR for visual analogue scale (VAS) and disability scale (DS). Patients were asked to score the satisfaction of their treatment as 1 (very poor) to 5 (excellent). Compliance to exercise program were graded as 1 (regularly performed), 2 (frequently performed), or 3 (rarely performed). RESULTS: Thirty-two patients with dizziness were included. Diagnosis of patients were vestibular migraine (n=5), Meniere's disease (n=2), vestibular neuritis (n=10), persistent perceptual positional dizziness (n=10), bilateral vestibulopathy (n=3), and central dizziness (n=2). Mean VAS and DS before VR were 15.3 and 2.4, respectively. Mean VAS and DS after VR were 4.5 and 0.7, respectively. Significant improvements in VAS and DS were observed after VR (p=0.00). Mean treatment satisfaction score was 3.3±1.0 and mean compliance score was 2.3±0.8. Satisfaction to VR showed positive correlation with patient's compliance. (p=0.00, r=0.644) CONCLUSIONS: Significant improvements were seen in symptom and disability in patients with acute and chronic dizziness after customized VR. Patients showed moderate compliance to exercise program and overall satisfaction was fair.

Objective:To analyze the site of vestibular nerve damaged in patients with acute vestibular neuritis. Methods:Fifty-seven patients with acute vestibular neuritis were recruited, and each patient underwent caloric irrigation test, video head impulse test（vHIT） and vestibular evoked myogenic potentials（VEMPs）. The results were further analyzed. Results:Analysis of abnormal rates of different vestibular function tests: the abnormal rate of caloric irrigation test, horizontal semicircular canal vHIT, anterior semicircular canal vHIT, and posterior semicircular canal vHIT were 92.98%, 92.98%, 92.98%, and 52.63%, respectively. The abnormal rate of cervical vestibular evoked myogenic potentials（cVEMP） and ocular vestibular evoked myogenic potentials（oVEMP） were 52.63% and 89.47%. The abnormal rate of caloric irrigation test, horizontal semicircular canal vHIT, anterior semicircular canal vHIT, and oVEMP were significantly higher than posterior semicircular canal vHIT and cVEMP（P<0.01）. Combination analysis of different vestibular function tests: there are twenty-six patients（45.61%, superior and inferior vestibular nerve） with abnormal caloric irrigation test, video head impulse test, and VEMPs. There are twenty-five patients（43.86%, superior vestibular nerve） with abnormal caloric irrigation test, horizontal semicircular canal vHIT, anterior semicircular canal vHIT, and oVEMP. There are 4 patients（7.02%, inferior vestibular nerve） with abnormal posterior semicircular canal vHIT and cVEMP. There are two patients（3.51%, ampullary vestibular nerve） with abnormal caloric irrigation test, horizontal semicircular canal vHIT, and anterior semicircular canal vHIT. The rate of superior and inferior vestibular neuritis and superior vestibular neuritis were significantly higher than inferior vestibular neuritis and ampullary vestibular neuritis（P<0.01）. Conclusion:Acute vestibular neuritis subtypes can be divided into four categories: superior and inferior vestibular neuritis, superior vestibular neuritis, inferior vestibular neuritis, and ampullary vestibular neuritis. Video head impulse test can accurately assess the site of vestibular nerve damage in patients with acute vestibular neuritis. In addition, vHIT combined with VEMPs can provide objective evidence for the diagnosis of ampullary vestibular neuritis.

Objective:This study aims to compare the examination results of the vestibular evoked myogenic potential（VEMP） and video head impulse testing（vHIT） in patients with vestibular neuritis（VN）, thus exploring the methods to distinguish superior and inferior vestibular nerve damages in VN patients, and their feasibility. Methods:A total of 25 patients with unilateral VN treated in the Otology Department of the First Hospital of Qinhuangdao from May 2018 to July 2021 were recruited. They were respectively tested for ocular VEMP（oVEMP）, cervical VEMP（cVEMP） and vHIT, and the examination results were analyzed. Results:Examination results of oVEMP showed that 96%（24/25） patients had one-ear abnormalities with the amplitude decline or no waveform introduced, and 4%（1/25） patient had no waveform introduced of both ears. The overall abnormal rate examined by oVEMP was 100%（26/26）. Examination results of cVEMP showed that 36%（9/25） patients had one-ear abnormalities with the amplitude decline or no waveform introduced, and 4%（1/25） patients had no waveform introduced of both ears. The overall abnormal rate examined by cVEMP was 40%（10/25）, and 60%（15/25） patients had normal waveforms of both ears. Examination results of vHIT showed that 100%（25/25） patients had semicircular canal gain decline of one side, 92%（23/25） had anterior Semicircular canal decline of one side, and 36%（9/25） had posterior semicircular canal decline of one side. VEMP and vHIT results were compared. Examination results of VEMP showed that 60%（15/25） VN patients had superior vestibular nerve damage, and 40%（10/25） had both superior and inferior vestibular nerve damages. Examination results of vHIT showed that 64%（16/25） VN patients had superior vestibular nerve damage, and 36%（9/25） had both superior and inferior vestibular nerve damages. There was no significant difference in the ratio of VN patients with superior and inferior vestibular nerve damages examined by VEMP or vHIT（χ²=0.085, P>0.05）. The matching ratio of VEMP and vHIT results was 80%（20/25）, and the non-matching ratio was 20%（5/25）. Conclusion:Consistent results obtained from both VEMP and vHIT can preliminarily identify the type of vestibular nerve damage. If their results are not consistent, it is recommended not to identify the scope of the vestibular nerve damage.

Objective: To explore the dynamic changes of vestibular autorotation test (VAT) before and after vestibular rehabilitation treatment in patients with unilateral vestibular hypofunction (UVH). Methods: A retrospective study was carried out,48 patients who were diagnosed with UVH and under vestibular rehabilitation in department of otorhinolaryngology, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, from January 2019 to January 2021 were enrolled. Among them, there were 21 males and 27 females, with an average age of 46.9 years old, including 25 cases of Meniere's disease, 13 cases of sudden deafness with vertigo and 10 cases of vestibular neuritis. The course of disease ranged from 5 days to 10 years. Demographic characteristics, detailed case data and routine examination were collected for the patients. The horizontal gain/phase, vertical gain/phase, and asymmetry of VAT at different frequencies before and after vestibular rehabilitation were collected. The absolute value of the difference between the measured value of 2.0-5.9 Hz before and after rehabilitation and the standard value were statistically analyzed. Results: Before vestibular rehabilitation, the incidence of abnormal gain was 62.5% (30/48), the incidence of abnormal phase was 56.3% (27/48), and the incidence of asymmetry was 16.7% (8/48). After 4-6 weeks of vestibular rehabilitation, the incidence of gain abnormality was 22.9% (11/48), the incidence of phase abnormality was 31.3% (15/48), and the incidence of asymmetry was 12.5% (6/48).The horizontal gain at frequency of 2.0-3.9 Hz showed statistically significant difference compared with before vestibular rehabilitation (P<0.05), and the horizontal gain at frequency of 4.3-5.9 Hz showed that there was no significant difference (P>0.05); the horizontal phase at 5.9 Hz showed that the difference was statistically significant (P=0.043), and there was no significant difference before and after rehabilitation treatment at 2.0-5.5 Hz (P>0.05); the vertical gain at 4.3 Hz showed the difference was statistically significant (P=0.020), and the remaining frequency showed no significant difference (P>0.05); No frequency of asymmetry and vertical phase showed the difference before and after rehabilitation was statistically significant (P>0.05). Conclusion: VAT can be used to monitor the change trend of multiple frequency bands before and after vestibular rehabilitation in UVH, in order to provide reference for the formulation of personalized rehabilitation strategies.

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.

Multiple sclerosis (MS) is a chronic disease characterized by multiple areas of demyelination, inflammation, and glial scarring in the central nervous system. MS is the most common chronic and usually progressive neurologic disease whose clinical course varies from a benign and symptom-free disease to a rapidly progressive and disabling disorder. MS can be presented with various symptoms, but isolated vertigo, represented in only 5%, is very rare. Nevertheless, in such a case, differential diagnosis of peripheral vestibular disease is very important for neuro-otologist. We recently experienced a 39 year-old female patient of multiple sclerosis with isolated vertigo mimicking vestibular neuritis. We report our case with a review of literature.

Although classical benign paroxysmal positional vertigo (BPPV) has generally been resolvable by routine manual repositioning maneuvers, nevertheless resistant cases and variant remain a significant problem. Recently, we experienced a case of posterior semicircular canal BPPV combined with changes to various types of BPPV during manual reposition maneuver and vestibular neuritis. We examined her brain MRI due to low response of routine manual reposition maneuvers and frequently recurrence of BPPV. In brain MRI, we found 1.3cm sized mass in hypoglossal canal. It seemed to be neuroma on hypoglossal nerve. A refractory BPPV poses problems of pathophysiogenetic interpretation, differential diagnosis with a CNS lesion and therapeutic strategy. We thought that refractory BPPV should be treated with more frequently examination and manual repositional maneuver and distinguished from CNS lesion.

Cerebral venous infarction is associated with a wide variety of clinical symptoms and signs, which may often delay appropriate diagnosis. Unilateral vestibular deficit as a presenting sign of cerebral venous infarction has rarely been reported. We report a patient with cerebral venous infarction who had severe prolonged vertigo, vomiting, occipital headache, positive head thrust testing, and unilateral caloric weakness as main clinical features. Although the patient had occipital headache, overall symptoms and signs closely mimicked those of acute peripheral vestibulopathy.

For differential diagnosis between vestibular neuritis and lateral medullary infarction with similar clinical features, bedside examination of nystagmus is important. We report a 45-year-old male who presented with acute vertigo for two days. He showed spontaneous right-beating nystagmus. However, left-beating nystagmus was evoked during bilateral horizontal gaze and by horizontal head oscillation. Brain MRI revealed an acute infarction in the left lateral medulla.
