A neuro-otological examination was given to 22 patients with paroxysmal positional vertigo within 1 week of head injury. In all cases, reverse rotatory positional nystagmus accompanied by a vertiginous sensation was observed in the positional nystagmus test. No relationship between the affected side and the direction of eye movement in the head-hanging position was found in the positional nystagmus test. From the prognosis and the nystagmus findings, the cause of the vertigo was thought to be partial damage to the inner ear. The clinical course was generally favorable, but recovery was slower in the 11 cases with neuro-otologically demonstrated central nervous system disorders than in the other 11 cases.
对22例头部受伤后1周内出现阵发性位置性眩晕的患者进行了神经耳科学检查。在所有病例中，位置性眼震试验均观察到反向旋转性位置性眼震并伴有眩晕感。在位置性眼震试验中，未发现患侧与头悬垂位时眼球运动方向之间存在关联。从预后和眼震检查结果来看，眩晕的原因被认为是内耳部分损伤。临床过程总体良好，但在11例经神经耳科学证实存在中枢神经系统疾病的患者中，恢复速度比其他11例患者慢。
