“…Theoretically, selective lesions involving either the HSC or the SSC are less likely given that both SCs share the same innervation through the superior vestibular nerve and the same vascular supply through the anterior vestibular artery. Therefore, an isolated HSC involvement on vHIT has been most frequently depicted in MD [52,53], while it has been rarely described in vestibular neuritis [54,55] and only anecdotally in cases of canalith jam [37]. On the other hand, an isolated SSC hypofunction has been mostly described in SSCD [44][45][46]49,50] and only sporadically in some variants of SSC-BPPV [39].…”

“…Similarly, acute ischemic lesions of the labyrinth can result in a selective SC dysfunction only when the common cochlear artery or its branches are involved, resulting in PSC and saccular involvement in association with sudden SNHL [36,40,41]. Besides the aforementioned dysfunctions, other inner ear disorders can account for a selective PSC impairment at the vHIT, including MD either in the acute or inter-ictal stage and atypical variants of PSC-BPPV [36,39,40,53,[57][58][59]. In these cases, alterations of the intralabyrinthine micromechanics should be considered as the underlying pathomechanism, likely because the physiological undermost position of the PSC increases its vulnerability to acute/chronic damages on a hydropic basis and to a sudden blockage of the endolymphatic flow due to otoconial dislodgements [38][39][40]58,59].…”

Posterior semicircular canal dehiscence (PSCD) has been demonstrated to result in a third mobile window mechanism (TMWM) in the inner ear similar to superior semicircular canal dehiscence (SSCD). Typical clinical and instrumental features of TMWM, including low-frequency conductive hearing loss (CHL), autophony, pulsatile tinnitus, sound/pressure-induced vertigo and enhanced vestibular-evoked myogenic potentials, have been widely described in cases with PSCD. Nevertheless, video-head impulse test (vHIT) results have been poorly investigated. Here, we present six patients with PSCD presenting with a clinical scenario consistent with a TMWM and an impaired vestibulo-ocular reflex (VOR) for the affected canal on vHIT. In two cases, an additional dehiscence between the facial nerve and the horizontal semicircular canal (HSC) was detected, leading to a concurrent VOR impairment for the HSC. While in SSCD, a VOR gain reduction could be ascribed to a spontaneous “auto-plugging” process due to a dural prolapse into the canal, the same pathomechanism is difficult to conceive in PSCD due to a different anatomical position, making a dural herniation less likely. Alternative putative pathomechanisms are discussed, including an endolymphatic flow dissipation during head impulses as already hypothesized in SSCD. The association of symptoms/signs consistent with TMWM and a reduced VOR gain for the posterior canal might address the diagnosis toward PSCD.

Endolymphatic hydrops (ELH) known as the main pathophysiology of Menière’s disease (MD) changes both the cochlear and vestibular function of the inner ear. These physiological changes can occur simultaneously (cochleovestibular involvement) or separately (cochlear or vestibular involvement). They can also present unilaterally or bilaterally (simultaneously or sequentially). Moreover, ELH recurs periodically without any specific etiology and known rhythm. Therefore, the patient referred for audiological tests may be in attack phase (acute) or inter-attack phase (chronic). MD itself may be in early- or advanced stage. In addition, considering comorbidity (vestibular or non-vestibular) is vital for differential diagnosis. On the other hand, each audiological test (including PTA, ECochG, VNG, vHIT, SVV, VEMPs …) has its specific diagnostic viewpoint and gives us a limited snapshot of MD’s clinical picture. Consequently, in this chapter, we want to discuss these viewpoints and try to explain associations and dissociations of audiological test findings in MD patients.

The interest in the diagnosis of common vestibular disorders in children and adults is permanently increasing. In this survey, the applications of the main diagnostic methods in this interdisciplinary field are briefly discussed. The diagnostic capacities of the caloric test, video head impulse test, cervical and ocular vestibular evoked myogenic potentials, videonystagmography, electrococheography, magnetic resonance imaging, computed tomography, etc. are summarized. Special attention is paid to some common vestibular disorders such as Menière's disease, benign paroxysmal positional vertigo, vestibular migraine, vestibular neuritis, and acute vestibular syndrome. United international efforts will contribute to further improvement of the diagnosis of the vestibular disorders, which warrants their adequate treatment.
