UNLABELLED Benign Positional Paroxysmal Vertigo (BPPV) is one of the most common vestibular diseases and the active head rotation test one of the most modern methods of vestibular function assessment. AIM this study aims to verify if the active head rotation test may reveal signs of horizontal and/or vertical vestibulo-ocular reflex dysfunction in vertigo patients suspected for BPPV. STUDY ...

Neurology 2012;78:154–156 Benign paroxysmal positional vertigo (BPPV) presentations are one of the unique opportunities in medicine when the care rendered can result in substantial benefit with extremely low risk for harm. Disabling symptoms are cured in minutes by moving the otolithic debris out of the semicircular canal, and the maneuvers to do this carry no more risk than that of lying down ...

OBJECTIVES Benign paroxysmal positional vertigo (BPPV) is the most frequent vestibular disorder. Although it is easily cured with canal repositioning maneuvers for the majority of patients, it can be disabling in rare cases. For these patients, surgical solutions may be proposed. The aim of this article is to review the techniques used, the reported cases in the literature, and to discuss their...

There is compelling evidence that free-floating endolymph particles in the posterior semicircular canal underlie most cases of benign paroxysmal positional vertigo (BPPV). Recent pathological findings suggest that these particles are otoconia, probably displaced from the otolithic membrane in the utricle. They typically settle in the dependent posterior canal and render it sensitive to gravity....

An acutely vertiginous 47-year-old woman presented to the emergency department with simultaneous acute left neurolabyrinthitis and left posterior canal benign paroxysmal positional vertigo (BPPV). Gaze nystagmus from the neurolabyrinthitis hampered diagnosis of the BPPV. However, once the BPPV was identified and treated, the patient's subjective vertigo improved rapidly. Concomitant BPPV should...

Benign paroxysmal positional vertigo (BPPV) is the most prevalent form of peripheral vertigo and is seen in a significant number of patients who present at neurology and ear, nose, and throat clinics. Various maneuvers may be used to determine the affected canal based on observation of specific nystagmus signs, and may also be used for treatment. Multiple canal pathology can make diagnosis and ...

We present an experimental model for a semicircular canal with canalithiasis. Canalithiasis is a pathological condition where free-floating particles disturb the flow field in the semicircular canals. It may lead to a specific form of vertigo known as BPPV or top-shelf vertigo. A careful scaling of the physical and geometrical parameters allows us to study the mechanics of this disease on an en...

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...

OBJECTIVE The prevalence of benign paroxysmal positional vertigo (BPPV) is becoming more frequent in elderly population. The presence of comorbid factors has to be considered before assessment as well as before commencing any repositioning treatment. Our aims were evaluation of the maneuvers efficacy and evaluation of the applicability of hybrid maneuver (HM) in patients with physical limitatio...

Benign paroxysmal positional vertigo (BPPV) occurs when there are freely moving particles in a semicircular canal and the head is turned in the plane of the affected canal. The aim of the present study was to clarify whether BPPV manifests equally in both labyrinths or whether there is a preponderance for one side. We conducted a PubMed literature search of BPPV case series which specified the ...
