Uneven Effects of Sleep Apnea on Semicircular Canals and Otolithic Organs

Frontiers in Neurology, 2022
ObjectiveThis study aimed to explore how obstructive sleep apnea (OSA) affects the function of each vestibular organ and to identify the correlations among them.MethodsA prospective study was conducted involving 32 healthy controls and 64 patients with ...

Inner ear morphology in the Atlantic molly Poecilia mexicana--first detailed microanatomical study of the inner ear of a cyprinodontiform species. [PDF]

PLoS ONE, 2011
BACKGROUND: 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.

Response of Vestibular Nerve Afferents Innervating Utricle and Saccule During Passive and Active Translations

Journal of Neurophysiology, 2009
The distinction between sensory inputs that are a consequence of our own actions from those that result from changes in the external world is essential for perceptual stability and accurate motor control. In this study, we investigated whether linear translations are encoded similarly during active and passive translations by the otolith system ...

Endolymph magnetic resonance imaging: Contribution of saccule and utricle analysis in the management of patients with sensorineural ear disorders

European Annals of Otorhinolaryngology, Head and Neck Diseases, 2020
Endolymphatic hydrops features excess endolymph in the membranous labyrinth, and is a marker of Menière's disease. Between the early 1980s and late 2000s, MRI in Menière's disease aimed purely to rule out tumor or malformation as differential diagnoses for the pressure disorder.

Membrane Stress in the Human Labyrinth and Meniere Disease: A Model Analysis

International Archives of Otorhinolaryngology, 2015
Introduction The nature and extent of membrane damage encountered in Meniere disease remains unexplained. Pressure-induced membrane stress may underlie the characteristic hydropic distention.

The Growing Evidence for the Importance of the Otoliths in Spatial Memory

Frontiers in Neural Circuits, 2019
Many studies have demonstrated that vestibular sensory input is important for spatial learning and memory. However, it has been unclear what contributions the different parts of the vestibular system – the semi-circular canals and otoliths – make to ...

Role of SoxE transcription factors in development and disease

Developmental Dynamics, EarlyView.
Abstract Sox8, Sox9, and Sox10 arose by multiple rounds of genome duplications from a single SoxE gene in ancestral vertebrates. In this review, we will briefly discuss the molecular structure and function of SoxE transcription factors and their evolutionary origin. We will then discuss their expression, function, and developmental disorders.

Acute histological reactions in the otolith organs to inner ear drug delivery through a cochlear implant

Frontiers in Neurology
IntroductionCochlear implantation is currently regarded as a safe and minimally invasive procedure. However, cochlear implantation can have an impact on vestibular function, despite the lack of correlation between patient symptomatology and damage in ...

First evidence of the link between internal and external structure of the human inner ear otolith system using 3D morphometric modeling

Scientific Reports, 2023
Our sense of balance is among the most central of our sensory systems, particularly in the evolution of human positional behavior. The peripheral vestibular system (PVS) comprises the organs responsible for this sense; the semicircular canals (detecting ...

Labyrinthine Abnormalities on MRI in Untreated Otosclerosis: Prevalence and Clinical Relevance

The Laryngoscope, EarlyView.
In untreated otosclerosis with labyrinthine symptoms, delayed 3D FLAIR MRI rarely demonstrates endolymphatic hydrops but frequently reveals blood–labyrinth barrier (BLB) disruption. BLB enhancement is spatially associated with cochlear endosteal and round window involvement and increases with the severity of the hearing loss phenotype.
