Vestibular-evoked myogenic potentials and video head impulse test in cochlear otosclerosis
The Egyptian Journal of Otolaryngology, 2023 Background Otosclerosis is one of the most common causes of hearing loss in adults with clinical onset between 20 and 40 years of age. Vestibular symptoms may be the most agonizing and primary symptom in cases with otosclerosis, so the assessment of ...

Characteristics of spontaneous nystagmus and its correlation to video head impulse test findings in vestibular neuritis. [PDF]
Front Neurosci, 2023 Objective To explore the direction and SPV (slow phase velocity) of the components of spontaneous nystagmus (SN) in patients with vestibular neuritis (VN) and the correlation between SN components and affected semicircular canals (SCCs). Additionally, we

Do measures of gain asymmetry and catch-up saccades improve video head impulse test agreement with caloric results? [PDF]
Clin Neurophysiol PractHighlights • Measures of gain asymmetry and catch-up saccades improve caloric and vHIT concordance in vestibular neuritis and vestibular schwannoma.• Discordant test results were most common in Ménière’s disease, irrespective of which vHIT outcome ...

Refining the Video Head Impulse Test Diagnostic Accuracy: A Case-Control Study.
Audiol Neurootol, 2023 Introduction: Current clinical practice considers the vestibulo-ocular reflex (VOR) gain as registered by the video head impulse test (vHIT) as the primary measure for semicircular canal function, while the role of the re-fixation saccades (RSs) is still

Video head impulse test (vHIT) unravels the hidden pathology in chronic vestibular deficit
The Egyptian Journal of OtolaryngologyBackground The caloric test is persistently altered in chronic peripheral vestibular hypofunction (PVH). So, we cannot depend on it to measure the degree of compensation in chronic vestibulopathy patients who are still complaining.
