Otopathologic Patterns of Cellular Degeneration in the Peripheral Vestibular Organ Secondary to Head Trauma. [PDF]

Laryngoscope
This study examines vestibular degeneration following head trauma, comparing cases with and without fractures. Histopathological analysis of 26 temporal bones showed more severe damage in nonfracture cases, particularly in Scarpa's ganglion cells and vestibular hair cells.

Ongoing Discrepancy Between Unilateral Meniere's Disease and Bilateral Endolymphatic Hydrops on Hydrops MRI. [PDF]

Laryngoscope Investig Otolaryngol
ABSTRACT Objective In the era of Hydrops MRI, a clinical dilemma has emerged: while Meniere's disease (MD) is diagnosed unilaterally, Hydrops MRI demonstrates endolymphatic hydrops (EH) bilaterally. This study aims to clarify this ongoing discrepancy. Methods Fifty‐six MD patients underwent an inner ear test battery followed by 3 T Hydrops MRI.

Case Report: Isolated Idiopathic Saccular Dysfunction

Frontiers in Neurology, 2021
Advances in vestibular testing have now allowed us to test each semicircular canal as well as the utricle and saccule, independently. This has led to the discovery of new patterns of vestibular dysfunction that were once impossible to evaluate.

A Synchrotron and Micro-CT Study of the Human Endolymphatic Duct System: Is Meniere's Disease Caused by an Acute Endolymph Backflow?

Frontiers in Surgery, 2021
Background: The etiology of Meniere's disease (MD) and endolymphatic hydrops believed to underlie its symptoms remain unknown. One reason may be the exceptional complexity of the human inner ear, its vulnerability, and surrounding hard bone.

Epithelial cell stretching and luminal acidification lead to a retarded development of stria vascularis and deafness in mice lacking pendrin. [PDF]

PLoS ONE, 2011
Loss-of-function mutations of SLC26A4/pendrin are among the most prevalent causes of deafness. Deafness and vestibular dysfunction in the corresponding mouse model, Slc26a4(-/-), are associated with an enlargement and acidification of the membranous ...

Advances in otolith-related protein research

Frontiers in Neuroscience, 2022
Otoliths are biological crystals formed by a layer of calcium carbonate crystal that adhere to the ciliary surface of the utricular and saccular receptors in the vestibule of all vertebrates inner ear, enabling the utricle and saccule to better perceive ...

Quantitative assessment of inner ear variation in elasmobranchs

Scientific Reports, 2023
Considerable diversity has been documented in most sensory systems of elasmobranchs (sharks, rays, and skates); however, relatively little is known about morphological variation in the auditory system of these fishes.

Reduced Vestibular Function is Associated With Cortical Surface Shape Changes in the Frontal Cortex. [PDF]

Hum Brain Mapp
We identified significant cortical surface shape changes in focal areas of the prefrontal cortex that correlate with age‐related vestibular dysfunction in 117 older adults from the Baltimore Longitudinal Study of Aging. These findings provide important insights into mechanisms linking vestibular decline, cognitive impairment, and fall risk in aging ...

Morphological analysis of the vestibular system of guinea pigs poisoned by organophosphate

Brazilian Journal of Otorhinolaryngology, 2016
INTRODUCTION: The vestibular system is responsible for body balance. There are substances that damage it, causing dizziness; these are termed vestibulotoxic substances.

Inner ear morphology in the Atlantic molly Poecilia mexicana [PDF]

, 2011
Fishes show an amazing diversity in hearing abilities, inner ear structures, and otolith morphology. Inner ear morphology, however, has not yet been investigated in detail in any member of the diverse order Cyprinodontiformes.
