Superior canal dehiscence syndrome – case report [PDF]

Romanian Journal of Neurology, 2012
We report a case of a patient with superior semicircular canal dehiscence syndrome, a recently described condition in which vestibular imbalance and/or hearing loss results from the discontinuity of the bone overlying the superior semicircular canals ...

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 ...

Observational study on risk factors determining residual dizziness after successful benign paroxysmal positional vertigo treatment: The role of subclinical BPPV [PDF]

, 2019
After successful treatment for benign paroxysmal positional vertigo, many patients may complain of residual dizziness. Possible explanations may be the persistence of otolith into canal insufficient to provoke noticeable nystagmus, utricular dysfunction ...

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 ...

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.

The Mechanics of the Growing Semicircular Canal [PDF]

Journal of Experimental Biology, 1973
ABSTRACT The motion of the endolymph in the semicircular canal is described with the aid of a linear second-order system, comprising the applied angular acceleration and the linear displacement, the linear velocity and the linear acceleration of the endolymph.
