Posturographic study in older patients with instability associated with benign paroxysmal positional vertigo: a prospective analysis

Caloric Analysis of Patients with Benign Paroxysmal Positional Vertigo.

OBJECTIVE The aim of this study is to compare nystagmus characteristics after caloric irrigation in patients with lateral canal (LC) and posterior canal (PC) benign paroxysmal positional vertigo (BPPV) and to analyze the role of symptom duration. MATERIALS AND METHODS A prospective study was conducted in 65 patients with BPPV (20 LC and 45 PC) who were subjected to caloric testing. Average sl...

Benign paroxysmal positional vertigo.

Benign paroxysmal positional vertigo (BPPV) is the most common cause of recurrent vertigo and has a lifetime prevalence of 2.4% in the general population. Benign paroxysmal positional vertigo is caused when calcium carbonate material originating from the macula of the utricle falls into one of the semicircular canals. Due to their density relative to the endolymph, they move in response to grav...

Benign Paroxysmal Positional Vertigo

Benign paroxysmal positional vertigo.

Benign paroxysmal positional vertigo (BPPV) is the most common and most treatable cause of vertigo. In most cases, a simple maneuver that takes less than a few minutes to do resolves the problem. BPPV is caused by misplaced calcium carbonate crystals (otoconia) in the semicircular canal of the inner ear that have broken free from the utricle. When these crystals break free, they either remain l...

Benign Paroxysmal Positional Vertigo

Dizziness and vertigo are among the most frequently encountered symptoms in primary care, with benign paroxysmal positional vertigo (BPPV) being the commonest type of vertigo. Its clinical course may vary considerably from a self-treatable to a persisting and/or recurrent disabling problem, with as yet unidentified prognostic factors. Although it is named as such, there are a considerable numbe...
