Operative Management of a Posterior Semicircular Canal Dehiscence
The Laryngoscope, 2006AbstractObjective: The objective of this study was to describe the operative management of posterior canal dehiscence.Methods: A transmastoid approach to and plugging of the posterior canal was performed for posterior semicircular canal dehiscence (PSCD).Results: Postoperatively, the patient exhibited improvement in conductive hearing loss and ...

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

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.

Posterior semicircular canal dehiscence secondary to jugular enlargement
American Journal of Otolaryngology, 2016Semicircular canal dehiscence is an important entity often presenting with symptoms of noise or pressure induced vertigo, autophony, aural fullness and conductive hearing loss. Due to its varied presentation and mimic of other otologic conditions its consideration is of increased importance. Within we report a case of right sided posterior semicircular

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 ...

Experimental selective posterior semicircular canal laser deafferentation
The Journal of Laryngology & Otology, 2005In 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,

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 ...

Posterior Semicircular Canal Occlusion for Intractable Benign Paroxysmal Positional Vertigo
Annals of Otology, Rhinology & Laryngology, 1990Benign paroxysmal positional vertigo (BPPV) is most often a self-limited disorder arising from the posterior semicircular canal of the undermost ear in the Hallpike position. Some individuals with this disorder have severe and protracted symptoms requiring more than expectant therapy.
