OBJECTIVE: To clarify the value of the new roll test in diagnosing posterior canal BPPV and elucidate the position that elicits nystagmus.
METHODS: The subjects were 100 consecutive patients (79 were female, 21 were male) with posterior canal BPPV. We classified the patients into four types based on a position that induced nystagmus.
RESULTS: The patient\'s position that elicited nystagmus varied. The supine type accounted for 24 %, the lateral type accounted for 62 %, the head-hanging type accounted for 9 %, and the DH type accounted for 5 %.
CONCLUSIONS: The new roll test is valuable for diagnosing posterior canalolithiasis cases. Most patients reveal vertical/torsional nystagmus in the supine or lateral position. Therefore, performing the new roll test first is efficient at the initial visit.
目的:阐明新的滚动试验在诊断后管BPPV中的价值,并阐明引起眼球震颤的位置。
方法:受试者为100名连续患者(79名女性,21人为男性),后管BPPV。我们根据诱发眼球震颤的位置将患者分为四种类型。
结果:引起眼球震颤的患者位置不同。仰卧型占24%,侧位型占62%,挂头型占9%,DH型占5%。
结论:新的滚动试验对后泪小管结石病例的诊断有价值。大多数患者在仰卧位或侧卧位显示垂直/扭转性眼震。因此,在初次访问时,首先执行新的滚动测试是有效的。
