Anterior canal BPPV and apogeotropic posterior canal BPPV: two rare forms of vertical canalolithiasis
Posterior canal benign paroxysmal positional vertigo (BPPV) is the most frequent form of BPPV. It is characterized by a paroxysmal positioning nystagmus evoked through Dix-Hallpike and Semont positioning tests. Anterior canal BPPV (AC) is more rare than posterior canal BPPV; it presents a prevalent down beating positioning nystagmus, with a torsional component clockwise for the left canal, coun...
متن کاملDown-beating nystagmus in anterior canal benign paroxysmal positional vertigo.
Down-beating positional nystagmus is typically associated with central nervous system disease. Anterior canal benign paroxysmal positional vertigo (AC-BPPV) can mimic down-beating positional nystagmus of central origin, particularly when it is bilateral. Factors that increase the probability of bilateral AC-BPPV include a history of bilateral multicanal BPPV, transient down-beating and torsiona...
متن کاملPersistent positional nystagmus: a case of superior semicircular canal benign paroxysmal positional vertigo?
Involvement of the superior semicircular canal (SSC) in benign paroxysmal positional vertigo (BPPV) is rare. SSC BPPV is distinguished from the more common posterior semicircular canal (PSC) variant by the pattern of nystagmus triggered by the Dix-Hallpike position: down-beating torsional nystagmus in SSC BPPV versus up-beating torsional nystagmus in PSC BPPV. SSC BPPV may be readily treated at...
متن کاملConduct after Epley's maneuver in elderly with posterior canal BPPV in the posterior canal.

متن کاملSurgical management for benign paroxysmal positional vertigo of the superior semicircular canal.
Benign paroxysmal positional vertigo of the superior semicircular canal is a rare form of BPPV. It accounts for 1% to 3% of cases. The characteristic nystagmus is positional, down-beating, with a torsional component elicited by the Dix-Hallpike maneuver. Symptoms of superior semicircular canal BPPV often resolve spontaneously; however, it can be refractory to repositioning maneuvers. Surgical m...
