“Sitting-up vertigo as an expression of posterior semicircular canal heavy cupula and posterior semicircular canal short arm canalolithiasis” [PDF]

Journal of Otology, 2022
Vestibular symptoms on sitting-up are frequent on patients seen by vestibular specialists. Recently, a benign paroxysmal positional vertigo (BPPV) variant which elicits vestibular symptoms with oculomotor evidence of posterior semicircular canal (P-SCC) cupula stimulation on sitting-up was described and named sitting-up vertigo BPPV.

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 ...

Apogeotropic Posterior Semicircular Canal BPPV—A Case Series from South Rajasthan [PDF]

Annals of Indian Academy of Neurology, 2023
Apogeotropic variant of posterior semicircular canal benign paroxysmal positional vertigo (apo-PSC-BPPV) is a rare peripheral vestibular disorder, characterized by paroxysms of positionally triggered dizzy spells associated with non-positional disequilibrium.

Posterior semicircular canal dehiscence: a diagnostic and surgical conundrum [PDF]

BMJ Case Reports, 2019
Third window defects have increasingly been identified as a cause of vertigo. These defects are bony dehiscences that occur in the bony labyrinth, resulting in abnormal pressure gradient in the inner ear fluids leading to sound (Tullio’s phenomenon) or pressure (Hennebert’s sign) induced vertigo. The superior semicircular canal dehiscence syndrome is a

Behavior of the Posterior Semicircular Canal after Dix-Hallpike Maneuver

Audiology Research, 2016
The objective of the present study is to analyze the quantitative vestibulo-ocular responses in a group of patients with benign paroxysmal positional vertigo (BPPV) canalolithiasis and compare these data with the data of the tridimensional biomechanical model.

Posterior semicircular canal dehiscence following endolymphatic sac surgery [PDF]

The Laryngoscope, 2012
AbstractPosterior semicircular canal dehiscence is a rare otologic entity that presents with third window signs and symptoms. Petrous apex cholesteatoma, fibrous dysplasia, high riding jugular bulb, and eosinophilic granuloma have been reported to be associated with posterior semicircular canal dehiscence.

Clinical Characteristics of Posterior and Lateral Semicircular Canal Dehiscence [PDF]

Journal of Neurological Surgery Part B: Skull Base, 2015
The objective of this study was to evaluate the characteristic symptoms of and treatments for lateral semicircular canal dehiscence (LSCD) and posterior semicircular canal dehiscence (PSCD) and its proposed mechanism. A dehiscence acquired in any of the semicircular canals may evoke various auditory symptoms (autophony and inner ear conductive hearing ...

Experimental study on the frog anterior semicircular canal in comparison with the posterior semicircular canal.

Equilibrium Research, 1986
The anterior semicircular canals of bull frogs were isolated, and the cupula was removed from the crista and the sensory cilia on the crista were depressed toward the canal side by a glass micropipette. Seven points on the crista were selected for stimulation.
