Fenestration and occlusion of the posterior semicircular canal for benign positional vertigo

Clinical Otolaryngology, 1992
Benign 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, 1968
A 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.

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,

Quantification of hearing loss in patients with posterior semicircular canal dehiscence

Acta Oto-Laryngologica, 2015
Patients 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.

Radiological prevalence of superior and posterior semicircular canal dehiscence in children

International Journal of Pediatric Otorhinolaryngology, 2015
Establishing the prevalence of semicircular canal dehiscence in a pediatric population using temporal bone CT imaging.Retrospective analysis of all temporal bone CT scans during a 5-year period (2007-2012).CT scan images were reformatted in the plane of the canals and assessed by two independent reviewers with a third to resolve disagreement.

A Comparative Study of the Isolated Anterior and Posterior Semicircular Canals of the Bull Frog

Acta Oto-Laryngologica, 1987
The anterior semicircular canals of bull frogs were isolated and the cupula was removed from the crista and the sensory cilia on the crista were depressed toward the canal side by a glass micropipette. Seven points on the crista were selected for stimulation.

Hearing and vestibular functions after plugging surgery for the posterior semicircular canal

Acta Oto-Laryngologica, 2008
Results of audiometry, caloric testing and vestibular evoked myogenic potential (VEMP) testing were hardly influenced by plugging surgery.To evaluate the influence of surgical plugging of the posterior semicircular canal on inner ear function in patients with benign paroxysmal positional vertigo (BPPV).The subjects were five consecutive patients with ...
