Persistent positional nystagmus: a case of superior semicircular canal benign paroxysmal positional vertigo?
Involvement of the superior semicircular canal (SSC) in benign paroxysmal positional vertigo (BPPV) is rare. SSC BPPV is distinguished from the more common posterior semicircular canal (PSC) variant by the pattern of nystagmus triggered by the Dix-Hallpike position: down-beating torsional nystagmus in SSC BPPV versus up-beating torsional nystagmus in PSC BPPV. SSC BPPV may be readily treated at...
متن کاملVestibulo-Ocular Reflex Abnormalities in Posterior Semicircular Canal Benign Paroxysmal Positional Vertigo: A Pilot Study
Introduction: Benign paroxysmal positional vertigo (BPPV), involving the semicircular canals, is one of the most common diseases of the inner ear. The video head impulse test (vHIT) is a new test that examines the function of the canals. This study aimed to investigate the vestibulo-ocular reflex (VOR) gain, gain asymmetry and saccades after stimulating all six canals in patients definitively d...
متن کاملAbout Nystagmus Transformation in a Case of Apogeotropic Lateral Semicircular Canal Benign Paroxysmal Positional Vertigo
THERE ARE TWO FORMS OF LATERAL SEMICIRCULAR CANAL BENIGN PAROXYSMAL POSITIONAL VERTIGO: geotropic and apogeotropic. When the pathophysiological mechanism of the apogeotropic form is that of canalolithiasis, we can observe a transformation from an apogeotropic nystagmus into a geotropic one. Usually, this phenomenon happens simultaneously on both sides, thus enabling us to observe a right-beatin...

متن کامل[Characteristic of nystagmus and treatment of horizontal semicircular canal benign paroxysmal positional vertigo].
OBJECTIVE To investigate the characteristic of nystagmus and treatment of horizontal semicircular canal benign paroxysmal positional vertigo (HSC-BPPV). METHOD The positioning nystagmic features in 43 patients with HSC-BPPV treated between April 2004 and October 2006 were recorded and analyzed with video nystagmography. After the subtype and the effect side were determined, the appropriate re...
