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).

Analysis of 30 patients with cupulolithiasis of the posterior semicircular canal

European Archives of Oto-Rhino-Laryngology, 2022
The diagnostic characteristics of patients with cupulolithiasis of the posterior semicircular canal are persistent torsional nystagmus in the supine position and persistent torsional nystagmus (opposite direction) in the nose-down position, which are caused by the affected canal becoming gravity sensitive.To investigate the clinical features of ...

Posterior semicircular canal occlusion in the normal hearing ear

Otolaryngology–Head and Neck Surgery, 1991
This report outlines our experience with posterior semicircular canal occlusion, a new operative procedure for intractable benign paroxysmal positional vertigo (BPPV). We postulate that the resulting solid canal “plug” prevents endolymph movement within the posterior canal, which effectively fixes the cupula.
