Development of semicircular canal occlusion

Frontiers in Neuroscience, 2022
Surgical treatment of vertigo is performed with in-depth study of inner ear diseases. Achieving an effective control of vertigo symptoms while reducing damage to hearing and reducing surgical complications is the principle followed by scholars studying surgical modalities. Semicircular canal occlusion is aimed at treatment of partial peripheral vertigo

Functional implications of ubiquitous semicircular canal non-orthogonality in mammals.

PLoS ONE, 2013
The 'canonical model' of semicircular canal orientation in mammals assumes that 1) the three ipsilateral canals of an inner ear exist in orthogonal planes (i.e., orthogonality), 2) corresponding left and right canal pairs have equivalent angles (i.e ...

Synergistic Lewis Acid Photocatalysis Over Cluster‐Defect‐Engineered UiO‐66 for Efficient Liquid Biomass Upgrading

Angewandte Chemie, EarlyView.
A cluster‐defect engineering strategy is presented for the rational design of Zn‐incorporated UiO‐66 photocatalysts. Selective acid etching mediates hierarchical porosity and abundant Lewis acid sites, tailoring the electronic structure and enhancing light harvesting.

Measurement of Human Semicircular Canal Spatial Attitude

Frontiers in Neurology, 2021
Located deep in the temporal bone, the semicircular canal is a subtle structure that requires a spatial coordinate system for measurement and observation.

Reduction of the vertical vestibular-ocular reflex in military aircraft pilots exposed to tactical, high-performance flight

Frontiers in Neurology, 2023
BackgroundExposure to high-performance flight stresses the vestibular system and may lead to adaptive changes in the vestibular responses of pilots. We investigated the vestibular-ocular reflex of pilots with different histories of flight exposure both ...

Quantitative analysis and correlative evaluation of video-oculography, micro-computed tomography, and histopathology in Pendrin-null mice

Neurobiology of Disease, 2023
Patients with SLC26A4 mutations exhibit highly variable hearing loss and vestibular dysfunction. Although Slc26a4 mutant mice similarly exhibit vestibular deficits, including circling behavior, head tilting, and torticollis, the underlying pathogenesis ...

Turning semicircular canal function on its head: dinosaurs and a novel vestibular analysis. [PDF]

PLoS ONE, 2013
Previous investigations have correlated vestibular function to locomotion in vertebrates by scaling semicircular duct radius of curvature to body mass. However, this method fails to discriminate bipedal from quadrupedal non-avian dinosaurs.

Speech Perception in Ménière Disease

International Archives of Otorhinolaryngology, 2023
Introduction Ménière disease (MD) affects the inner ear, comprising the cochlea and semicircular canals. Symptoms include severe incapacitating vertigo, nausea, vomit, aural fullness, and sensorineural hearing loss – in which speech ...

Management of Lateral Semicircular Canal Benign Paroxysmal Positional Vertigo

Frontiers in Neurology, 2020
Benign paroxysmal positional vertigo (BPPV) is the most common cause of peripheral vestibular vertigo. It is caused by free-floating otoconia moving freely in one of the semicircular canals (canalolithiasis) or by otoliths adhered to the cupula ...
