[Horizontal and anterior canal benign paroxysmal positional vertigo].
Benign paroxysmal positional vertigo (BPPV) is suspected when the patient complains of brief episodes of vertigo induced by changes in the head position. The direction of the positional nystagmus during the positional maneuvers is essential to affirm the canal involved. There is a consensus for the diagnosis of a PC-BPPV and HC-BPPV (geotropic and ageotropic form) as well as for the treatment of a PC-BPPV and a geotropic HC-BPPC. However, there is still a debate for the diagnosis of an AC-BPPV and the treatment of an ageotropic HC-BPPV and an AC-BPPV.
