Functional Dissociation Between Cervical VEMP and Posterior Canal vHIT in 1770 Unselected Ears

open access: yesThe Laryngoscope, EarlyView.
Cervical VEMP and posterior canal vHIT are conventionally treated as measures of a single inferior vestibular unit. In 1770 unselected ears from a diagnosis‐agnostic registry, the two tests disagreed in 72.7% of ears abnormal on at least one test, with chance‐corrected agreement near zero (κ = 0.097) and unchanged across age strata.

Preferential Impairment of the Contralesional Posterior Semicircular Canal in Internuclear Ophthalmoplegia

open access: yesFrontiers in Neurology, 2017
BackgroundThe vertical vestibulo-ocular reflex (VOR) may be impaired in internuclear ophthalmoplegia (INO) as the medial longitudinal fasciculus (MLF) conveys VOR-signals from the vertical semicircular canals.

Factors Associated With Bilateral Involvement in Non‐Infectious Labyrinthitis: A Case–Control Study

open access: yesThe Laryngoscope, EarlyView.
Non‐infectious labyrinthitis may progress from unilateral to bilateral inner‐ear involvement, resulting in greater functional impairment. In this retrospective case–control study of 50 patients, younger age, female sex, and the presence of systemic disease were associated with bilateral involvement. These exploratory findings may help identify patients

Magnetic Vestibular Stimulation in Subjects with Unilateral Labyrinthine Disorders

open access: yesFrontiers in Neurology, 2014
We recently discovered that static magnetic fields from high-strength MRI machines induce nystagmus in all normal humans, and that a magnetohydrodynamic (MHD) Lorentz force, derived from ionic currents in the endolymph and pushing on the cupula, best ...

Rapid Postmortem Temporal Bone Extraction and Dissection of Human Inner Ear Organs From Organ Donors

open access: yesThe Laryngoscope, EarlyView.
We developed a postmortem protocol for temporal bone extraction and dissection in organ donors, enabling atraumatic bilateral temporal bone retrieval within 1–2 h of ischemia, followed by stepwise microsurgical dissection of neurosensory organs. Combining rapid extraction, abbreviated decalcification, and atraumatic microsurgical dissection, this ...

Sympathetic nerve activity during natural stimulation of horizontal semicircular canals in humans

open access: yes, 1998
We have shown that static head-down neck flexion elicits increases in muscle (MSNA) but not skin sympathetic nerve activity (SSNA) in humans. These findings suggest that stimulation of the otolith organs causes differential sympathetic outflow to ...

CHARGE Syndrome: What an Otolaryngologist Should Know—A Systematic Review and Meta‐Analysis

open access: yesOtolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective To synthesize the prevalence of otolaryngologic manifestations in CHARGE syndrome (CS) to support otolaryngologists in delivering comprehensive management. Data Sources PubMed/MEDLINE, Embase, and Google Scholar were searched for English‐ and French‐language studies published from January 1980 through January 2025.

Mechanical, rheological, and durability performances of GGBS‐based concrete for potential application to prestressed structures

open access: yesStructural Concrete, EarlyView.
Abstract Ground granulated blast‐furnace slag (GGBS) is a widely used clinker substitute in concrete, recognized for its potential to significantly reduce environmental impacts. However, its application in prestressed concrete remains limited in several countries, mainly due to concerns regarding early‐age mechanical performance and long‐term ...

Baclofen affects the semicircular canals but not the otoliths in humans

open access: yes, 2013
: Conclusion: This study showed that GABAB agonist baclofen (10 mg) affects the semicircular canals (SCCs), both centrally and peripherally, but does not influence the otolithic function.
