本文报告240例良性位置性眩晕（BPV）的临床及眼电图特点。在每种情况下，从坐姿到头悬挂位置的快速位置变化后，直观地观察到刻板的扭转阵发性位置性眼震，并用眼震电图（ENG）记录。平均发病年龄为54岁，范围为11至84岁。在略多于一半的病例（122/240）中，确定了可能的诊断。最常见的可识别原因是头部创伤（17%）和病毒性神经鞘炎（15%）。在特发性组中，女性人数超过男性，约为2：1。47%的患者在双温冷热试验中发现异常。只有两名患者，都有明确的神经系统疾病，有中央体征的ENG。我们的数据是一致的外周，后半规管起源的BPV。
We report the clinical and oculographic features in 240 patients with benign positional vertigo (BPV). In each case, after a rapid position change from the sitting to head-hanging position, a stereotyped torsional paroxysmal positional nystagmus was visually observed and recorded with electronystagmography (ENG). The mean age of onset was 54 years, with a range of 11 to 84 years. In slightly more than one-half of the cases (122/240) a likely diagnosis was determined. The most common identifiable causes were head trauma (17%) and viral neurolabyrinthitis (15%). Females outnumbered males approximately two to one in the idiopathic group. Abnormalities on bithermal caloric testing were found in 47% of patients. Only two patients, both with well-documented neurologic disorders, had central signs on ENG. Our data are consistent with a peripheral, posterior semicircular canal origin of BPV.
