“…In 61 % of our Meniere´s disease patients VEMPs were not found and in 39 % they were present. These fi ndings correlate with the literature (1,2,8,10,18,19,33), and indicate that there are a lot of patients having pathologic VEMP responses, e.i. a contribution of sacullar damage may be supposed in the Meniere´s disease, as well.…”

Objective: This study presents the role of vestibular evoked myogenic potentials (VEMPs) in the vestibular system investigation focused on the function of the saccule and inferior portion of the vestibular nerve. The main goal of the study is to report VEMP fi ndings in different groups of patients with inner ear disorders symptoms and to identify some clinical application of this test in our patients. Material and methods: WE have examined 218 patients with cochleovestibular symptomatology (sudden sensorineural cochlear hearing loss, retrocochlear hearing loss, vestibular neuronitis, benign paroxysmal positional vertigo (BPPV), Meniere´s disease, central vestibular disorder, as well as vertigo of non vestibular ethiology and 32 patients with conductive hearing loss with VEMP testing. We performed I channel and II channels measurements. Results: We found no VEMP response in the group of conductive or mixed hearing loss in all cases-100 % of 32 patients, in sudden sensorineural cochlear hearing loss in 35.4 % of 48 patients, in retrocochlear hearing loss in 19 % of 26 patients, in vestibular neuronitis in 40 % of 35 patients , in (BPPV) in 10 % of 43 patients, in Meniere´s disease in 61 % of 18 patients, in non vestibular vertigo in no case of 22 patients and in central vestibular disorders in 35 % of 23 patients. Conclusion: The present study shows the potential value of VEMP investigation in periferal vestibulopathy diagnosis (Tab. 1, Fig. 7, Ref. 33).

BackgroundThe literature on predictors of persistent postural-perceptual dizziness (PPPD) following peripheral vestibular insults has not been systematically reviewed.MethodsWe systematically reviewed studies on predictors of PPPD and its four predecessors (phobic postural vertigo, space-motion discomfort, chronic subjective dizziness and visual vertigo). Investigations focused on new onset chronic dizziness following peripheral vestibular insults, with a minimum follow-up of 3 months. Precipitating events, promoting factors, initial symptoms, physical and psychological comorbidities and results of vestibular testing and neuroimaging were extracted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.ResultsWe identified 13 studies examining predictors of PPPD or PPPD-like chronic dizziness. Anxiety following vestibular injury, dependent personality traits, autonomic arousal and increased body vigilance following precipitating events and visual dependence, but not the severity of initial or subsequent structural vestibular deficits or compensation status, were the most important predictors of chronic dizziness. Disease-related abnormalities of the otolithic organs and semi-circular canals and age-related brain changes seem to be important only in a minority of patients. Data on pre-existing anxiety were mixed.ConclusionsAfter acute vestibular events, psychological and behavioural responses and brain maladaptation are the most likely predictors of PPPD, rather than the severity of changes on vestibular testing. Age-related brain changes appear to have a smaller role and require further study. Premorbid psychiatric comorbidities, other than dependent personality traits, are not relevant for the development of PPPD.

“…10 Other studies confirmed this observation, with incidences ranging from 36% to 49%. 4,6,7,11 In 2002, Halmagyi et al, 29 using the HIT to measure the VOR, stated that VN can involve the inferior and superior vestibular nerves together or can induce selective injury of the superior vestibular nerves. Moreover, they reported 2 patients who had isolated posterior semicircular canal deficits on the HIT, suggesting a selective loss of inferior vestibular nerve function.…”

“…1-13 The vestibular dysfunction involves both the superior and inferior vestibular nerves and may affect them selectively. The incidence of involvement of the inferior vestibular nerve, which is less frequent than the reported superior vestibular nerve involvement, 1-16 ranged from 36% to 49% in different series. Although various studies have assessed the recovery of the superior vestibular nerve by testing the function of the horizontal semicircular canal through the caloric response, 1,3,12,13 few have investigated the recovery pattern of otolith dysfunction after a vertigo attack due to VN.…”

The implementation of C-VEMPs, O-VEMPs, and the vHIT in a vestibular diagnostic protocol has made it possible to observe patients with ampullary VN in a way that has not been feasible with other types of vestibular examinations. The age of the patient seems to have some impact on recovery from VN. When recovery occurs in the utricular and saccular nerves first and in the ampullary nerves subsequently, it may be reasonable to expect a more favorable outcome.
