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 ...

Tullio phenomenon in superior semicircular canal dehiscence (SSCD) [PDF]

open access: yes, 2015
A 68-year-old woman presented with worsening sound-induced vertigo (Tullio phenomenon) and left-sided hearing loss. Weber's test lateralised to the affected ear and audiography confirmed mild conductive hearing loss.

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

open access: yesAmerican 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.

Hennebert's sign in superior semicircular canal dehiscence syndrome: A Video Case Report [PDF]

open access: yes, 2012
Superior semicircular canal dehiscence (SSCD) syndrome has been called the great otologic mimicker because its presentation overlaps with otosclerosis, Meniere's disease, perilymphatic fistula, and patulous eustachian tube. A valuable examination finding

Asymmetrically severe internal auditory canal hypoplasia: A case report. [PDF]

open access: yes, 2020
We present a case of an otherwise healthy 20-month-old with congenital sensorineural hearing loss. CT and MR imaging demonstrated bilateral asymmetrically severe hypoplasia of the internal auditory canals and vestibulocochlear nerves.

Study the biomechanical performance of the membranous semicircular canal based on bionic models

open access: yesHeliyon, 2022
A BA (bionic ampulla) was designed and fabricated using an SMPF (Symmetric electrodes Metal core PVDF Fiber) sensor, which could imitate the sensory hair cells to sense the deformation of the cupula of the BA. Based on the BA, a bionic semicircular canal

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 ...

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

open access: yesAudiology 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

The number of procedures required to eliminate positioning nystagmus in benign paroxysmal positional vertigo [PDF]

open access: yes, 2005
AIM: To evaluate the number of weekly canalith repositioning procedures needed to eliminate positioning nystagmus in patients with benign paroxysmal positional vertigo and to verify influences of canalithiasis or cupulolithiasis and/or semicircular canal
