Conclusion: Logon is superior to click to trigger larger and more consistent vestibular evoked myogenic potentials (VEMPs).
Objectives: To record and compare the parameters of VEMPs evoked by bone- and air-conducted logon (l-VEMPs) and click (c-VEMPs).
Subjects And Methods: Air- and bone-conducted l-VEMPs and c-VEMPs were recorded in 28 normal ears with an Amplaid MK12 (Amplaid, Milan) equipment.
Results: VEMPs response rate was 100% with both air-conducted logon and click, while l-VEMPs showed a higher response rate (79%) in comparison with c-VEMPs (21%) with bone-conducted stimuli. A significant (p<0.05) increase of P1, N1 and P1-N1 amplitude and augmented P1 and N1 latencies were noticed in l-VEMPs with respect to c-VEMPs.

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.
Vestibular Function in Patients With Vestibular Neuritis Experiencing Prodromal Dizziness.

Department of Otolaryngology and Head and Neck Surgery, Graduate School of Medicine, The University of Tokyo, Tokyo, Japan.
Introduction: It is unknown whether prodromal dizziness (PD) before an attack of vestibular neuritis (VN) has an association with peripheral vestibular lesions. The purpose of this study was to investigate whether the severity of vestibular dysfunction has an association with the presence of PD.
Methods: We reviewed the medical records of 88 consecutive unilateral VN patients with unilateral canal paresis in caloric testing.
Effect of induced astigmatism on vestibulo-ocular reflex.

Clinical Relevance: The vestibular-ocular reflex stabilises the retinal image and maintains balance during head movement. Astigmatism is one of the common refractive errors that can reduce the quality of visual inputs.
Background: The purpose of this study was to investigate the effect of induced astigmatism on the function of the vestibular-ocular reflex.

An 11-year-old male Bengal tiger () was referred for a 2-week history of ambulatory tetraparesis, generalized ataxia, and hypermetric gait, associated with mild right head tilt and spontaneous proprioceptive deficit on the right forelimb. Neuroanatomical localization was C1-C5 myelopathy; cerebellum-vestibular system involvement was also considered. Hematology and serum biochemistry were unremarkable, although serum vitamin A (0.
