Inferior Vestibular Nerve

Vestibular schwannoma (VS) originates from Schwann cells in the superior or inferior vestibular nerve. Identifying the precise origin will help in determining the optimal surgical approach. We retrospectively analyzed the preoperative vestibular function test according to VS origin to determine whether the test is a valuable indicator of tumor origin. Forty-seven patients with VS (male:female = 18:29, mean age: 54.06 ± 13.50 years) underwent the cochleovestibular function test (pure-tone audiometry, caloric test, video head impulse test (vHIT), cervical and ocular vestibular-evoked myogenic potential, and posturography). All patients then underwent surgical removal of VS, and the schwannoma origin was confirmed. The tumor originated from the superior vestibular nerve (SVN group) in 21 patients, the inferior vestibular nerve (IVN group) in 26 patients, and an undetermined site in eight patients. The only value that differed significantly among the groups was the gain of the vestibular-ocular reflex (VOR) in the ipsilesional posterior canal (iPC) during the vHIT. Our results indicate that VOR gain in the iPC may be used to predict the nerve origin in patients with VS. Other cochleovestibular function tests have limited value to discriminate nerve origins, especially in cases of medium to large VS.

Susac Syndrome

BACKGROUND: Susac syndrome (retino-cochleo-cerebral vasculopathy, SuS) is an autoimmune endotheliopathy characterized by the clinical triad of encephalopathy, branch retinal artery occlusions and sensorineural hearing loss. In contrast to data regarding auditory function, data measuring vestibular function is sparse and the cervical vestibular-evoked myogenic potentials (cVEMPs). OBJECTIVE: To determine whether the video head impulse test (vHIT) can serve as a confirmatory assessment of vestibulocochlear dysfunction in cases of suspected SuS. METHODS: Seven patients diagnosed with SuS underwent pure tone audiometry, a word recognition test, cVEMPs and the vHIT. RESULTS: Five patients were diagnosed with definite SuS, and two with probable SuS. Two patients were asymptomatic for hearing loss or tinnitus, and no sensorineural hearing loss was detected by audiograms. Four patients complained of tinnitus, and three patients reported experiencing vertigo. Three patients had abnormal cVEMPs results. All seven patients’ vHIT results were normal, except for patient #2, who was one of the three who complained of vertigo. The calculated gain of her left anterior semicircular canal was 0.5, without saccades. CONCLUSIONS: This is the first study to describe the results of the vHIT and cVEMPs among a group of patients with SuS. The results suggest that the vHIT should not be the only exam used to assess the function of the vestibular system of SuS patients.

Objectives: This study aims to determine the prevalence of vestibular dysfunction in the Malaysian elderly and its association with presbycusis, age and other associated risk factors. Methods: A cross-sectional study was undertaken in a tertiary otorhinolaryngology department and the community. Adults aged 60 years and above who attended the ORL CLINIC with or without presbycusis were invited to participate. The main outcome measures, including the Malay Version Vertigo Symptoms Scale, pure tone audiometry and vestibular assessment, were obtained using a Video Head Impulse Test (VHIT). Results: The prevalence of vestibular dysfunction with presbycusis in the study population of 135 participants was 46.7 per cent (95 per cent confidence interval, 24.0 to 36.2 per cent). The median age was 68 years (range, 60–86 years). The A chi-square test of independence showed that there was significant association between Presbycusis and Tinnitus, X2 (1, N = 135) = 97.37, p < .001. A chi-square test of independence was performed to examine the relation between presbycusis and dizziness. The relation between these variables was significant, X2 (2, N = 135) = 28.42, p < .001. A chi-square test of independence showed that there was no significant association between presbycusis and VHIT, X2 (1, N = 135) = .01, p = .938. Conclusion: Vestibular dysfunction is independently associated with ageing and presbycusis. More research investigating the advantages of additional screening for vestibular dysfunction in older presbycusis patients is needed.
