A New Coordinate System for Magnetic Resonance Imaging of the Vestibular System

open access: yesFrontiers in Neurology, 2022
Objectives: To develop and evaluate a new coordinate system for MRI of the vestibular system.Methods: In this study, 53 internal auditory canal MRI and 78 temporal bone CT datasets were analyzed. Mimics Medical software version 21.0 was used to visualize

Video head impulse test in children after cochlear implantation [PDF]

open access: yesVojnosanitetski Pregled, 2019
Background/Aim. Cochlear implantation (CI) is a therapeutic modality that provides a sense of sound to children and adults with profound sensorineural hearing loss or deafness.

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

open access: yesJournal 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.

open access: yesPLoS 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 ...

Semicircular canal morphology in Rodentia and its relationship to locomotion. [PDF]

open access: yesJ Anat
Here, we present a selection of rodent inner ear 3D models in the lateral view, with rodents from seven locomotor categories (left to right: fossorial, semifossorial, semiaquatic, terrestrial, ricochetal, arboreal, and gliding). Semicircular canal (SCC) morphology, including radius of curvature and shape, can be differentiated between specialized forms

Superior Canal Dehiscence Syndrome: Lessons from the First 20 Years

open access: yesFrontiers 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 ...

Bilateral semicircular canal aplasia

open access: yesEuropean 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.

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

open access: yesPLoS 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.
