Posterior Semicircular Canal Dehiscence with Vestibulo-Ocular Reflex Reduction for the Affected Canal at the Video-Head Impulse Test: Considerations to Pathomechanisms [PDF]
Audiology ResearchPosterior semicircular canal dehiscence (PSCD) has been demonstrated to result in a third mobile window mechanism (TMWM) in the inner ear similar to superior semicircular canal dehiscence (SSCD).

“Sitting-up vertigo as an expression of posterior semicircular canal heavy cupula and posterior semicircular canal short arm canalolithiasis” [PDF]
Journal of Otology, 2022 Background: 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 ...

Posterior semicircular canal dehiscence: a diagnostic and surgical conundrum. [PDF]
BMJ Case Rep, 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

Preferential Impairment of the Contralesional Posterior Semicircular Canal in Internuclear Ophthalmoplegia [PDF]
Frontiers in Neurology, 2017 BackgroundThe 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.

Spontaneous Jamming of Horizontal Semicircular Canal Combined with Canalolithiasis of Contralateral Posterior Semicircular Canal. [PDF]
J Audiol Otol, 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 ...

Diagnosis and treatment of the short-arm type posterior semicircular canal BPPV [PDF]
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 ...

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 ...
