Benign paroxysmal positional vertigo: diagnosis and treatment.
Benign paroxysmal positional vertigo is a common disorder in Neurotology. This vestibular syndrome is characterized by transient attacks of vertigo, caused by change in head position, and associated with paroxysmal characteristic nystagmus. The symptoms result from movement of the free floating otoconia particles in the endolymph or their attachment to the cupulae of the semicircular canal. The...
متن کاملDiagnosis 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....
متن کاملBenign paroxysmal positional vertigo without nystagmus: diagnosis and treatment.
UNLABELLED Nystagmus tests to diagnose BPPV are still relevant in the clinical evaluation of BPPV. However, in everyday practice, there are cases of vertigo caused by head movements, which do not follow this sign in the Dix-Hallpike maneuver and the turn test. AIM To characterize BPPV without nystagmus and treatment for it. MATERIALS AND METHODS A non-systematic review of diagnosis and trea...
متن کاملBenign 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...
متن کاملBenign Paroxysmal Positional Vertigo
Benign paroxysmal positional vertigo is a disorder of the peripheral vestibular system characterized by brief episodes of vertigo precipitated by head movements in certain planes. It is one of the most common causes of vertigo. Displaced otolithic debris in the posterior semicircular canal is the proposed mechanism of this disorder and explains the success of repositioning procedures in treatin...
