回顾分析95例良性阵发性位置性眩晕(BPPV)诊断方法,并评价有效的检查和检查程序安排。应用的检查方法有:①病史及专科检查,脑干诱发电位;②检查自发性或位置性眼球震颤(PN)用Frenzel眼镜观察眼震电图(ENG)记录,并作视动眼震检查,作Dix-Hallpike位置试验;③Bithermal冷热试验;④旋转试验;⑤前庭习服锻炼(VHT)动作。试验标准:①DHM出现短暂的PN伴眩晕;②ENG在一个或多个位置上记录到眼震伴眩晕;③VHT一组动作中至少一个操作中出现PN。上列三项任一阳性可确诊。结果:95例中67例有典型的诱发性眩晕史,28例症状描述不典型。
A retrospective analysis of 95 cases of benign paroxysmal positional vertigo (BPPV) diagnostic methods, and evaluation of effective inspection and examination procedures. Application of the inspection methods are: ① history and specialist examination, brainstem evoked potentials; ② check spontaneous or positional nystagmus (PN) with Frenzel glasses observed electronystagmography (ENG) recording, and as the dynamic eye nystagmus examination, For Dix-Hallpike position test; ③ Bithermal hot and cold test; ④ rotation test; ⑤ vestibular uniform exercise (VHT) action. Test criteria: ① DHM transient PN with vertigo; ②ENG at one or more locations recorded nystagmus with vertigo; ③ VHT a group of actions in at least one operation PN. Any of the above three positive can be diagnosed. Results: Of the 95 cases, 67 cases had a history of typical induced vertigo, and the symptoms of 28 cases were not typical.
