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 ...

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 ...

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

Posterior Semicircular Canal Dehiscence: Case Series and Systematic Review
Otology & Neurotology, 2020Objective:To conduct a systematic review of posterior semicircular canal dehiscence (PSCD) and to present a series of patients with PSCD with and without classic third-window symptoms.Data Sources:PubMed, Scopus, and the Cochrane Library from inception until April 2019.

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 ...

Fenestration and occlusion of the posterior semicircular canal for benign positional vertigo
Clinical Otolaryngology, 1992Benign positional vertigo is a potentially disabling condition characterized by episodic vertigo following certain provocative head movements. In most patients it is self limiting; however, in a few it may prove intractable, causing considerable social morbidity. In these patients surgery may be considered.

Action potentials in the nerve from the posterior semicircular canal of the cat
Canadian Journal of Physiology and Pharmacology, 1968A method is described to implant electrodes for recording the electrical activity in the branch of the vestibular nerve from the posterior semicircular canal of the cat. A tungsten electrode eroded to a point is inserted into the nerve through the internal auditory meatus and held in position with dental cement.

Quantification of hearing loss in patients with posterior semicircular canal dehiscence
Acta Oto-Laryngologica, 2015Patients with posterior semicircular canal dehiscence (PSCD) have low frequency conductive hearing loss similar to patients with superior semicircular canal dehiscence (SSCD) secondary to a pathologic third window.PSCD can result in conductive hearing loss, but the magnitude of this hearing loss remains to be quantified.

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,

Direction-reversing Nystagmus in Horizontal and Posterior Semicircular Canal Canalolithiasis
Otology & Neurotology, 2016To investigate the incidence and characteristics of direction-reversing nystagmus in patients with horizontal (HSCC) and posterior semicircular canal (PSCC) canalolithiasis, and evaluate the effect of direction-reversing nystagmus on the treatment outcome.A retrospective study.Between March 2014 and September 2015, 63 and 92 consecutive patients with ...
