Benign Paroxysmal Positional Vertigo (BPPV)

Fluidmechanics of Benign Paroxysmal Positional Vertigo (bppv)

Particulate flow in the semicircular canals of the inner ear is suspected to be the most common cause for vertigo. This pathologic condition is known as benign paroxysmal positional vertigo (BPPV). We propose an analytical model for this flow configuration which consists of an equation for the fluid flow and of an equation of motion for the particles including the appropriate Stokes drag and gr...

Diagnosis and management of benign paroxysmal positional vertigo (BPPV).

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....

Differentiation of migrainous positional vertigo (MPV) from horizontal canal benign paroxysmal positional vertigo (HC-BPPV).

This article presents an approach to differentiation of migrainous positional vertigo (MPV) from horizontal canal benign paroxysmal positional vertigo (HC-BPPV). Such an approach is essential because of the difference in intervention between the two disorders in question. Results from evaluation of the case study presented here revealed a persistent ageotropic positional nystagmus consistent wi...

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...
