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%.

Radiological patterns of the posterior semicircular canal

Surgical and Radiologic Anatomy, 2013
The identification and definition of the radiological patterns of the posterior semicircular canal (PSC), with a view to obtain readily applicable conclusions.The parietal morphology of the PSC has been studied by multi-slice helical computed tomography (Philips Brilliance 6).

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

Isolated bilateral posterior semicircular canal hypofunction: comparison with bilateral vestibulopathy

Acta Oto-Laryngologica, 2023
Chronic unsteadiness is a common complaint at vestibular clinics. Bilateral vestibulopathy (BVP) is a major cause of chronic unsteadiness but is often overlooked. Although diagnostic criteria for BVP have been established by the Barany Society, isolated vertical canal hypofunction can remain undiagnosed.

Enhanced Retrosigmoid Exposure with Posterior Semicircular Canal Resection

Otolaryngology–Head and Neck Surgery, 1996
A subset of patients with acoustic neuromas and useful hearing have tumors that are inadequately approached by both middle fossa and retrosigmoid techniques. The enhanced retrosigmoid technique combines the hearing preservation of posterior semicircular canal ablation to achieve lateral internal auditory canal exposure with the ample cerebellopontine ...

Experimental selective posterior semicircular canal laser deafferentation

The Journal of Laryngology & Otology, 2005
In this experimental study, we attempted to perform selective deafferentation of the posterior semicircular canal ampulla of guinea pigs using carbon dioxide laser beam. The results of this study document the efficacy of this procedure in achieving deafferentation of the posterior semicircular canal safely with regards to the other semicircular canals,
