Posterior semicircular canal dehiscence: a morphologic cause of vertigo similar to superior semicircular canal dehiscence

European Radiology, 2003
The aim of this study was to assess imaging findings of posterior semicircular dehiscence on computed tomography and to evaluate incidence of posterior and superior semicircular canal dehiscence in patients presenting with vertigo, sensorineuronal hearing loss or in a control group without symptoms related to the inner ear.

Radiological prevalence of superior and posterior semicircular canal dehiscence in children

International Journal of Pediatric Otorhinolaryngology, 2015
Establishing the prevalence of semicircular canal dehiscence in a pediatric population using temporal bone CT imaging.Retrospective analysis of all temporal bone CT scans during a 5-year period (2007-2012).CT scan images were reformatted in the plane of the canals and assessed by two independent reviewers with a third to resolve disagreement.

Dehiscence of the posterior semicircular canal

American Journal of Otolaryngology, 2015
Semicircular canal dehiscence (SCD) is a condition of the inner ear wherein the temporal bone adjacent to the vestibular apparatus thins or erodes completely. It has no clear epidemiological predisposing factors that have been identified to date. Its diagnosis is made difficult by a clinical presentation that often overlaps with other pathologies of ...

Congenital Dehiscence in the Posterior Semicircular Canal

Otology & Neurotology, 2013
Posterior semicircular canal dehiscence (PSCD) may be of congenital origin.PSCD is characterized by the lack of bone coverage, which results in its lumen being exposed to the meninges of the posterior cranial fossa or to the gulf of the jugular vein. It has an incidence of 0.2%.

Cochlear implantation and simultaneous posterior semicircular canal plugging

Cochlear Implants International, 2022
Intractable benign paroxysmal positional vertigo (BPPV) may be treated by plugging the affected semicircular canal (SCC). A cochlear implant (CI) can diminish subjective symptoms of tinnitus. We present a case with intractable BPPV and incapacitating tinnitus who underwent surgery, simultaneously plugging his posterior SCC (PSCC) and implanting an ...

Posterior semicircular canal dehiscence in asymptomatic ears

Acta Oto-Laryngologica, 2010
This study revealed that, in the adult population, the final diagnosis of this entity can only be made by combining imaging with clinical tests.We developed the largest temporal bone multislice computed tomography (CT) scan study so far by including 410 cases to investigate the prevalence of posterior semicircular canal dehiscence in patients with ...

Cupulolithiasis of the posterior semicircular canal

American Journal of Otolaryngology, 2013
We sometimes experience patients with persistent torsional/vertical (upbeating) positional nystagmus in the head-hanging position. We have been convinced of the existence of cupulolithiasis of the posterior semicircular canal because such cases reveal persistent torsional/vertical (downbeating) positional nystagmus in the nose-down position.In order to

Posterior semicircular canal cupulolithiasis during acute pontomedullary demyelination

Practical Neurology, 2023
Positional vertigo poses a diagnostic challenge in people with multiple sclerosis (MS). The characteristics of positional nystagmus and its response to repositioning manoeuvres are usually sufficient to diagnose benign paroxysmal positional vertigo (BPPV).
