Benign paroxysmal positional vertigo (BPPV) is the most common form of vertigo. It is caused by loose otoconia from the utricle which, in certain positions, displaced the cupula of the posterior semicircular canal. BPPV most often is a result of aging. It also can occur after a blow to the head. Less common causes include a prolonged positioning on the back (supine) during some surgical procedu...

Acute peripheral vestibulopathy, of which the chief complaint is positional vertigo, comprises benign paroxysmal positional vertigo (BPPV), labyrinthitis, labyrinthine fistula, and cerebellopontine angle tumors. Since the typical presentation of labyrinthine fistulas may be sensorineural hearing loss, positional vertigo, or disequilibrium, it is often difficult to distinguish from BPPV or Menie...

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...

OBJECTIVES The prognostic significance of vertigo in patients with idiopathic sudden sensorineural hearing loss (SSNHL) remains a matter of debate because vertigo is associated with many different vestibular disorders. The purpose of this study is to determine the role of benign paroxysmal positional vertigo (BPPV) as a prognostic factor in patients with SSNHL. METHODS We conducted a retrospe...

OBJECTIVE To investigate the efficacy of postural restriction after canalith repositioning in treating benign paroxysmal positional vertigo (BPPV). DESIGN Prospective trial of patients with postural restriction vs those without postural restriction after treatment. PATIENTS Patients with classic BPPV and with BPPV without nystagmus were treated using the modified Epley canalith repositionin...

We evaluated 4 men who had benign paroxysmal positional vertigo (BPPV) that occured several hours after intensive mountain biking but without head trauma. The positional maneuvers in the planes of the posterior and horizontal canals elicited BPPV, as well as transitory nystagmus. This was attributed to both the posterior and horizontal semicircular canals (SCCs) on the left side in 1 patient, i...

OBJECTIVE To clarify the pathophysiological basis of persistent geotropic positional nystagmus (PGN) in patients with the horizontal canal type of benign paroxysmal positional vertigo (H-BPPV), the time constant (TC) of nystagmus and the relationship between its slow phase eye velocity (SPV) and the angle of head rotation in supine were defined. METHODS Geotropic or apogeotropic positional ny...

INTRODUCTION Benign paroxysmal positional vertigo (BPPV) is the most common cause of peripheral vestibular dysfunction. OBJECTIVE To assess whether the performance of the Dix-Hallpike maneuver after the Epley positioning maneuver has prognostic value in the evolution of unilateral ductolithiasis of posterior semicircular canal. METHODS A prospective cohort study in monitored patients at oto...

OBJECTIVE To prospectively test the efficacy of a device for the home treatment of benign paroxysmal positional vertigo (BPPV). DESIGN Multicenter prospective cohort study. SETTING Community and tertiary care clinic offices and patient homes. PATIENTS Forty patients with active BPPV. INTERVENTIONS Training on and treatment with a home treatment device (The DizzyFIX) as their primary the...
