OBJECTIVE The aim of the study was to evaluate the true incidence, diagnosis, and treatment of benign paroxysmal positional vertigo (BPPV) arising after whiplash injury and to distinguish this type of posttraumatic vertigo from other types of dizziness complained after trauma. METHODS This was a retrospective study comprising patients referred to our center after whiplash injury. The patients...

UNLABELLED Benign Paroxysmal Positional Vertigo (BPPV) is one of the most common causes of dizziness; it constitutes the most common vestibular disorder in the elderly with vertigo. Its characteristic clinical aspect is dizziness at head movement, with not hearing alteration. AIM This paper aims at studying the audiologic characteristics of elderly with BPPV of the posterior semicircular cana...

The pathophysiology of benign paroxysmal positional vertigo (BPPV) is not completely understood. Although the concept of degenerated otoconia transforming the posterior canal (PC) crista into a gravity-sensitive sense organ has gained popular support, several temporal bone (TB) series have revealed similar deposits in normal TBs, suggesting they are a normal change in the aging labyrinth. Furth...

Bull frogs posterior semicircular canals (psc) wee used to simulate the condition of benign paroxysmal positional vertigo (BPPV). The psc was isolated in frog Ringer's solution, and the saccular otoconia were used as a responsible material to stimulate the cupula. When the otoconia were placed on the cupular surface to mimic the condition of cupulolithiasis, the psc ampullary nerve action poten...

Benign paroxysmal positional vertigo (BPPV) is a common disorder caused by the dislocation of otoconia most commonly into the posterior canal. The primary symptoms are brief episodes of head-position related vertigo which may be accompanied by nausea and disequilibrium. BPPV is usually managed conservatively with excellent results, however in a small number of cases the symptoms can become pers...

British Journal of General Practice, September 2010 moved quickly ‘from a sitting position to lying with the head tipped 45 ̊ below the horizontal, 45 ̊ to the side, and with the side of the affected ear (and semicircular canal) downwards.’ The Dix-Hallpike test is positive when torsional (rotatory) nystagmus occurs when the head is turned to the affected ear. In a prospective study of diagnosis ...
