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.
当患者主诉因头部位置改变诱发短暂眩晕发作时，应怀疑为良性阵发性位置性眩晕（BPPV）。位置试验期间位置性眼震的方向对于确定受累半规管至关重要。对于后半规管BPPV和水平半规管BPPV（地向性和背地向性形式）的诊断以及后半规管BPPV和地向性水平半规管BPPV的治疗，已有共识。然而，对于前半规管BPPV的诊断以及背地向性水平半规管BPPV和前半规管BPPV的治疗仍存在争议。
