Posterior semicircular canal dehiscence in asymptomatic ears
Acta Oto-Laryngologica, 2010This 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 ...

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.

Cupulolithiasis of the posterior semicircular canal
American Journal of Otolaryngology, 2013We 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

Children with posterior semicircular canal dehiscence: A case series
International Journal of Pediatric Otorhinolaryngology, 2019Posterior semicircular canal dehiscence is a rare condition and can cause a variety of symptoms. We report three cases of children between 5 and 12 years of age with a PSCD. They all presented with different complaints as follows: Tullio phenomenon in the first case, conductive hearing loss in the second and, conductive hearing loss and pulsatile ...

Enhanced Retrosigmoid Exposure with Posterior Semicircular Canal Resection
Otolaryngology–Head and Neck Surgery, 1996A 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 ...

A third window of the posterior semicircular canal: An animal model
The Laryngoscope, 2010AbstractObjectives/Hypothesis:A third window in the vestibular apparatus has been investigated in both animals and humans, specifically in superior semicircular canal dehiscence. There are as yet no animal model studies of the effect of a third vestibular window of the posterior semicircular canal.Study Design:Original basic research study.Methods:A ...

Posterior semicircular canal cupulolithiasis during acute pontomedullary demyelination
Practical Neurology, 2023Positional 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).

Posterior semicircular canal nystagmus is conjugate and its axis is parallel to that of the canal
Neurology, 2000A patient with a postoperative fistula of the left posterior semicircular canal is presented. Negative pressure in the external ear canal produced upbeat-torsional nystagmus, which was recorded in three dimensions using binocular scleral search coils. The nystagmus was conjugate, without skew deviation, and its trajectory corresponded to the anatomic ...
