This study investigated ocular vestibular-evoked myogenic potential (oVEMP) tests via Fpz and Fz taps to assess the role of the frontal sinus in mediating oVEMP elicitation. Forty healthy subjects and 80 patients with Ménière disease (MD) underwent a series of oVEMP tests via a minishaker tapping at the Fpz and Fz sites in a randomized order. Response rates of oVEMP test via various tapping sites were compared. Dimensions of the frontal sinus were measured via CT scan. A significantly negative correlation between the age and height of the frontal sinus was noted, and the cutoff age for discriminating present and absent Fpz oVEMPs in MD patients was 52 years...

This study aimed to compare cervical vestibular-evoked myogenic potentials (cVEMP), ocular vestibular-evoked myogenic potentials (oVEMP) and video head impulse test (vHIT) results between patients with type 2 diabetes mellitus (DM) or diabetic polyneuropathy (DPN) and healthy controls to determine vestibular end-organ pathologies. The participants in the present study consisted of three groups: the type 2 DM group (n = 33 patients), the DPN group (n = 33 patients), and the age- and sex-matched control group (n = 35)...

BACKGROUND: The cervical vestibular evoked myogenic potential (cVEMP) represents an inhibitory reflex of the saccule measured in the ipsilateral sternocleidomastoid muscle (SCM) in response to acoustic or vibrational stimulation. Since the cVEMP is a modulation of SCM electromyographic (EMG) activity, cVEMP amplitude is proportional to muscle EMG amplitude. We sought to evaluate muscle contraction influences on cVEMP peak-to-peak amplitudes (VEMPpp), normalized cVEMP amplitudes (VEMPn), and inhibition depth (VEMPid)...

OBJECTIVE: Postoperative vertigo is a common complaint after cochlear implantation, but published incidence rates differ vastly. The aim of the present study was to investigate both subjective complaints of vertigo before and after cochlear implantation and related vestibular diagnostic tests on cochlear implant candidates. DATA SOURCES: We performed a systematic literature search according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement in PubMed, Cochrane Register, and EMBASE...

Vestibular evoked myogenic potentials are currently the most clinically accessible method to evaluate the otolith reflex pathways. These responses provide unique information regarding the status of the utriculo-ocular and sacculo-collic reflex pathways, information that has previously been unavailable. Vestibular evoked myogenic potentials are recorded from tonically contracted target muscles known to be innervated by these respective otolith organs. Diagnosticians can use vestibular evoked myogenic potentials to better evaluate the overall integrity of the inner ear and neural pathways; however, there are specific considerations for each otolith reflex protocol...

OBJECTIVE: To assess vestibular function in patients with familial dysautonomia (FD), a hereditary sensory and autonomic neuropathy - caused by a mutation in the IKBKAP gene (c.2204 + 6 T>C) - and characterized by marked gait ataxia. METHODS: Cervical and vestibular evoked myogenic potentials (cVEMPs and oVEMPs) were recorded from the sternocleidomastoid (SCM) and extraocular muscles in 14 homozygous patients, 2 heterozygous patients, and 15 healthy controls during percussion of the forehead...

OBJECTIVE: Noise has been recognized as a major cause of cochlear damage resulting in both tinnitus and hearing loss. On the other hand, damage to the vestibular system, especially the saccule, can be considered as a potential problem. The cervical vestibular-evoked myogenic potentials (cVEMPs) have been established as a clinical test of measuring both sac-cular and inferior vestibular nerve function. Therefore, it is thought to be sensitive to the noise-induced damage to the vestibular system...

OBJECTIVE: Cervical spondylosis and cervical disk herniation are the most frequent forms of degenerative disease in the cervical spine. Surgical treatment mainly includes anterior cervical disk fusion. However, information concerning vestibular-evoked myogenic potential (VEMP) recording in patients undergoing cervical spine surgery is limited. The present prospective study aimed to investigate the effect of anterior disk fusion surgery on cervical VEMP (cVEMP) parameters. MATERIALS AND METHODS: Twenty-five patients were enrolled in this study, and 20 patients (10 men and 10 women) completed cVEMP testing...

A number of electrophysiological tests have been proposed for the initial diagnostic assessment or for the follow-up phase of patients affected by Ménière disease. The most common are: (i) vestibular evoked myogenic potentials (VEMPs); (ii) electrocochleography (ECochG); and (iii) otoacoustic emissions (OAEs). This paper presents the latest clinical developments with these 3 testing modalities. The PubMed, Embase, and Cinahl databases were searched from 2006 to December 2016. Full-text articles were obtained in cases where the title, abstract, or key words suggested that the study may be eligible for this review...

Vertigo is a multisensory syndrome that otolaryngologists are confronted with every day. With regard to the complex functions of the sense of orientation, vertigo is considered today as a disorder of the sense of direction, a disturbed spatial perception of the body. Beside the frequent classical syndromes for which vertigo is the leading symptom (e.g. positional vertigo, vestibular neuritis, Menière's disease), vertigo may occur as main or accompanying symptom of a multitude of ENT-related diseases involving the inner ear...

Cervical vestibular-evoked myogenic potentials (cVEMPs) are accepted to demonstrate the vestibulo-collic reflex. However, the brainstem pathway is still not fully understood. The aim of the study was to evaluate the contribution of cVEMPs to detection of brainstem involvement in multiple sclerosis (MS). Thirty patients fulfilling the criteria for definite MS were included in the study. All were newly diagnosed cases, admitted due to an attack with active lesions on MRI. Thirty-one age- and sex-matched healthy controls constituted the control group...

BACKGROUND: Superior canal dehiscence syndrome (SCDS) is a relatively rare neurotological disorder that is characterized by a heterogeneous clinical picture. Recently, vestibular evoked myogenic potential (VEMP) measurement was established for the diagnosis of SCDS. In the present study, a case series of patients with SCDS were analyzed, with a focus on VEMP. METHODS: Four patients with SCDS were prospectively examined with ocular VEMP (oVEMP) and cervical VEMP (cVEMP)...

The authors provide an update on the clinical manifestations, diagnosis and various approaches to the treatment of superior semicircular canal dehiscence (SSCD). SSCD is a rare condition where the bone overlying the superior semicircular canal thins or dehisces causing characteristic clinical findings. Since this was first reported in 1998 by Minor and colleagues, there has been much advancement made in terms of diagnosis and treatment. Signs and symptoms include a wide variation of both vestibular and auditory manifestations...

OBJECTIVE: To elucidate the clinical features and vestibular symptoms of patients with otolith organ dysfunction in the presence of normal function of the semicircular canals. METHODS: We reviewed the clinical records of 277 consecutive new patients with balance disorders who underwent testing of cervical and ocular vestibular evoked myogenic potentials (cVEMPs and oVEMPs) as well as caloric testing and video head impulse testing (vHIT). RESULTS: We identified 76 patients who showed normal caloric responses and normal vHIT findings in each SCC plane, but abnormal responses in cVEMP and/or oVEMP testing...

Horizontal OD was quantified by using the axial T2-weighted fast-spin echo (FSE) images of the brain at 1...
