Diagnosis and treatment of the short-arm type posterior semicircular canal BPPV

Brazilian Journal of Otorhinolaryngology, 2022
Introduction: The Epley maneuver is useful for the otoconia to return from the long arm of the posterior semicircular canal into the utricle. To move otoconia out of the posterior semicircular canal short arm and into the utricle, we need different ...

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

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.

Preferential Impairment of the Contralesional Posterior Semicircular Canal in Internuclear Ophthalmoplegia [PDF]

Frontiers in Neurology, 2017
The vertical vestibulo-ocular reflex (VOR) may be impaired in internuclear ophthalmoplegia (INO) as the medial longitudinal fasciculus (MLF) conveys VOR-signals from the vertical semicircular canals. It has been proposed that signals from the contralesional posterior semicircular canal (PSC) are exclusively transmitted through the MLF, while for the ...

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 ...

Posterior semicircular canal dehiscence following endolymphatic sac surgery [PDF]

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.

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.

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 ...

An Uncommon Case of Bilateral Posterior and Superior Semicircular Canal Dehiscence Syndrome [PDF]

International Journal of Anatomy Radiology and Surgery, 2020
Semicircular Canal Dehiscences (SCD) are rare and involvement of Posterior Semicircular Canal (PSCC) and/or multiple dehiscences are even rarer. A dehiscence of any of the semicircular canals may produce various auditory or vestibular symptoms by ...

Association between superior semicircular canal dehiscence and other dehiscences in temporal bone

Folia Morphologica, 2020
BACKGROUND: The study of the association between superior semicircular canal and other dehiscences in the temporal bone. MATERIALS AND METHODS: We have studied computed tomography of radiologically diagnosed people with superior or posterior semicircular
