“…As demonstrated in Table 2, it has been noticed by previous studies that even though caloric test usually demonstrates an asymmetry toward the affected ear, vHIT parameters are usually preserved in definite MD (22)(23)(24)(25)(26)(27)(28)(29)(30). Some authors tried to evaluate if this discrepancy in the results may be in relation to the duration or the stage of MD but failed to find a significant relationship (25,27,29).…”

“…This leads to propose that the presence of an abnormal caloric response in the presence of a normal vHIT results may be used as a marker in the diagnosis of MD. However, a recent study raised doubts as they failed to find an association between caloric/vHIT discrepancy and the pathophysiological marker of MD, namely, EH (28). They used an inner ear MRI to classify MD patients based on the presence or absence of a positive sign of EH.…”

Usefulness of Video Head Impulse Test Results in the Identification of Meniere's Disease

Meniere's disease (MD) is an inner ear disorder inducing tinnitus, aural fullness, sensorineural hearing loss, and vertigo episodes. In the past few years, efforts have been made to develop objective measures able to distinguish MD from other pathologies. Indeed, some authors investigated electrophysiological measures, such as electrocochleography and vestibular evoked myogenic potentials or imaging techniques. More recently, the video head impulse test (vHIT) was developed to assess the vestibulo-ocular reflex (VOR). In the last few years, authors aimed at identifying how vHIT may help to identify MD. The objective of this manuscript is to review the different vHIT results in MD patients. We will discuss the usefulness of these findings in the identification of MD, how these results may be explained by pathophysiological mechanisms associated with MD, and finally provide directions for future studies.

“…When considering studies with data regarding vHIT and Cal in patients diagnosed with MD, dissociation for these tests has been reported in 30–91%; most commonly normal gains on vHIT and canal paresis on Cal [ 9 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ]. These results may vary according to the active or inactive phase of the disease.…”

“…During unilateral MD attacks (active phase), both tests can be normal in 10–38%, both abnormal in 2–40%, low gains on vHIT and normal Cal in 18–30%, and normal gains on vHIT and hypofunction on Cal in 20–60% [ 26 , 28 , 30 , 36 ]. While in the inactive phase, 10–49% of patients have been reported to have abnormal findings in both tests, and 35–82% of the cases presented dissociation, where 9–18% had low gains on vHIT and normal response on Cal while 18–74% had normal gains on vHIT and hypofunction on Cal [ 9 , 26 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 37 ]. There is considerable variability for both test results, and their concordance rates.…”

Vestibular assessment tests such as the video head impulse test (vHIT) for the horizontal semicircular canal, and caloric test (Cal), both evaluate horizontal canal function. One would assume that the outcomes for these tests should lead to concordant results, yet several studies have suggested that dissociation can occur in certain pathological conditions. As this topic remains inconclusive, this review aims to analyze the scientific evidence regarding the patterns of hypofunction observed in vHIT and Cal in different otoneurological diseases. A comprehensive review of the literature regarding dissociation between these tests in common neurotological diseases was carried out. Articles were analyzed when data for vHIT and Cal were described in a way that it was possible to calculate discordance rates; both retrospective and prospective studies were analyzed. In this review, the discordance rates were as follows: 56% in Ménière’s disease, 51.5% in vestibular migraine, 37.2% in vestibular schwannoma, and 20.8% in vestibular neuritis. These results highlight the benefit of using both Cal and vHIT, and that they are complementary tests.

“…While, Sluydts et al (10) and Guo et al (6) reported that the abnormal caloric tests was correlated with the severity of vestibular. Moreover, few studies have focused on the relationships between semicircular canal hydrops and vestibularocular reflex (VOR) recorded by video head impulse test (vHIT) (11,12).…”

Background: Currently, 3 Tesla-MRI following intratympanic gadolinium injection has made it possible to assess the existence and the severity of hydrops in each compartment of the endolymphatic spaces in vivo. However, the relationship between vestibular endolymphatic hydrops (EH) visualized by MRI and vestibular functional tests, especially the correlation between caloric test, video-head impulse test, and semicircular canal hydrops, has not been well-investigated.Objective: The purpose of this study is to investigate the relationship between the severity of EH in each compartment of otoliths and semicircular canal and the results of vestibular functional tests.Methods: In this retrospective study, we performed three-dimensional fluid-attenuated inversion recovery (3D-FLAIR) sequences following intratympanic gadolinium injection in 69 unilateral patients with definite Menière's disease. Vestibular and lateral semicircular canal hydrops was graded on MRI using a four grade criterion. All patients underwent pure-tone audiometry, cervical vestibular evoked myogenic potential (cVEMP), ocular vestibular evoked myogenic potential (oVEMP), caloric test and video head impulse test (vHIT). The latency, amplitude and asymmetry ratio of VEMP, canal paresis (CP) and vestibulo-ocular reflex (VOR) gain of lateral semicircular canal of vHIT were collected. The correlation analysis were performed between the parameters of function test and EH.Results: Vestibular EH showed correlations with the duration of disease (r = 0.360) and pure tone average (r = 0.326). AR of cVEMP showed correlations with Vestibular EH (r = 0.407). CP (r = 0.367) and VOR gain of lateral semicircular canal at 60 ms (r = 0.311) showed correlations with lateral semicircular canal hydrops.Conclusion: EH in different compartments is readily visualized by using 3D-FLAIR MRI techniques. The degree of vestibular EH correlated with AR of cVEMP and EH in the semicircular canal ampullar affects the caloric and vHIT response in patients with unilateral Meniere‘s disease.
