Objective: This study aimed to define the characteristics and use of ocular and cervical vestibular evoked myogenic potentials for evaluating paediatric cochlear implant candidates.
Methods: Ocular and cervical vestibular evoked myogenic potentials of 34 paediatric cochlear implant candidates were analysed. All patients also underwent a routine audiological examination, including computed tomography.
Results: In all, 27 patients with normal inner-ear structures had absent or impaired vestibular evoked myogenic potential responses. In paediatric candidates with inner-ear malformations, ocular and cervical vestibular evoked myogenic potentials had lower thresholds and higher amplitudes. Vestibular evoked myogenic potential responses in this cohort were classified into three groups. There was significant concordance between vestibular evoked myogenic potentials and temporal bone computed tomography findings.
Conclusion: Ocular and cervical vestibular evoked myogenic potential waveforms were different in paediatric candidates with normal and abnormal inner-ear structures. Therefore, vestibular evoked myogenic potential responses can indicate temporal bone structure.

Gravitational changes have been shown to cause significant abnormalities in various body systems, including the cardiovascular, immune, vestibular, and musculoskeletal systems. While numerous studies have examined the response of the vestibular system to gravitational stimulation, research on functional changes in the peripheral inner ear remains limited. The inner ear comprises two closely related structures: the vestibule and cochlea.

Background/objectives: The auditory middle-latency responses (AMLRs) assess central sensory processing beyond the brainstem and serve as a measure of sensory gating. They have clinical relevance in the diagnosis of neurological conditions. In this study, magnitude and habituation of the AMLRs were tested for sensitivity and specificity in classifying dizzy patients with vestibular migraine (VM) and post-concussive syndrome.

Objective: The study aimed to explore the vestibular function in children with neurodevelopmental disorders (NDDs).
Methods: Twenty-eight participants with a NDD (6 girls, 22 boys; 6-13 years; 9;3 ± 2;4 years) were enrolled in this pilot study. Sixteen participants had a single NDD (Autism Spectrum Disorder: n = 7, Developmental Coordination Disorder: n = 3; Attention Deficit/Hyperactivity Disorder: n = 6), the remaining 12 had comorbid NDDs.

To analyse the 3D-Flair MRI manifestations of the inner ear, vestibular function status, and their correlation with hearing treatment outcomes in patients with severe sudden sensorineural hearing loss (SSNHL), and to explore potential prognostic indicators for sudden deafness. The clinical data of adult patients with unilateral profound sudden sensorineural hearing loss were retrospectively analyzed in Otorhinolaryngology Department of Shandong Provincial ENT Hospital from March 2018 to August 2020. Patients were categorized based on the results of their inner ear 3D-Flair MRI into two groups: the normal MRI group and the abnormal MRI group.

Purpose: The present study examined masseteric vestibular evoked myogenic potential (mVEMP) responses in children and compared these results with those of adults, using both air- and bone-conduction modes of stimulation.
Method: Fifteen children and fifteen adults with hearing thresholds below 15 dB HL were considered for the study. Ipsilateral 500-Hz narrow-band chirp (NB CE-chirp) evoked mVEMP responses were elicited via a zygomatic montage through both air- and bone-conduction modes of stimulation.
