Simulation Study of Canal Switching in BPPV

Frontiers in Neurology, 2022
The objective of this research was to investigate the mechanism of canal switching in benign paroxysmal positional vertigo through a virtual simulation model.

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

Spontaneous Jamming of Horizontal Semicircular Canal Combined with Canalolithiasis of Contralateral Posterior Semicircular Canal [PDF]

Journal of Audiology and Otology, 2022
Spontaneous canalith jam is an uncommon form of benign paroxysmal positional vertigo mimicking acute vestibular neuritis. We described for the first time a spontaneous horizontal semicircular canalith jam associated with a typical canalolithiasis involving contralateral posterior semicircular canal (PSC), illustrating how the latter condition modified ...

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 ...

Bilateral semicircular canal aplasia

European Annals of Otorhinolaryngology, Head and Neck Diseases, 2013
Bilateral semicircular canal aplasia is extremely rare; discovery, when the cochlear-vestibular system is normal and there is no hearing loss, is serendipitous.Bilateral semicircular canal aplasia was serendipitously discovered in a 24-year-old male during assessment of unilateral mixed hearing loss with subnormal contralateral hearing.

Prevalence of Superior Semicircular Canal Dehiscence on High-Resolution CT Imaging in Patients without Vestibular or Auditory Abnormalities

American Journal of Neuroradiology, 2019
BACKGROUND AND PURPOSE: Prior studies of radiologic superior semicircular canal dehiscence have suggested that CT may overcall dehiscence. However, many of those studies were performed before the advent of multichannel helical CT.

Superior Canal Dehiscence Syndrome: Lessons from the First 20 Years

Frontiers in Neurology, 2017
Superior semicircular canal dehiscence syndrome was first reported by Lloyd Minor and colleagues in 1998. Patients with a dehiscence in the bone overlying the superior semicircular canal experience symptoms of pressure or sound-induced vertigo, bone ...

Apogeotropic variant of horizontal semicircular canal benign paroxysmal positional vertigo: Where are the particles?

Audiology Research, 2019
The apogeotropic variant of horizontal semicircular canal benign paroxysmal positional vertigo (HC-BPPV) is attributed to free floating particles in the anterior arm of the lateral semicircular canal – particles attached to the cupula facing the canal or

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.

Investigation Into the Dynamics of the Cupula in the Vestibular Organ of Adult Zebrafish Using Metabolic Glycoengineering

Angewandte Chemie, EarlyView.
The cupula is a membrane within the vestibular organ that senses rotatory accelerations of the head. Metabolic glycoengineering in combination with bioorthogonal labeling demonstrates that in adult zebrafish – being a model for the human inner ear – this membrane is constantly renewed.
