180°翻滚试验在水平半规管良性阵发性位置性眩晕患侧判别中的作用

The additional 180° roll test in the determination of affected side of horizontal semicircular canal benign paroxysmal positional vertigo

目的:探讨180°翻滚试验在确定水平半规管良性阵发性位置性眩晕(HSC-BPPV)患侧中的作用。方法:回顾性分析初次就诊于耳鼻咽喉科眩晕门诊的106例HSC-BPPV患者,对90°翻滚试验无法确定患侧的26例患者补充行180°翻滚试验,并根据所诱发眼震的性质和强度判断患侧。结果:26例通过反复90°翻滚试验无法确定患侧,补充180°翻滚试验后有10例可以确定患侧。结论:临床上常规90°翻滚试验无法确定HSC-BPPV患侧时,联合180°翻滚试验可进一步提高患侧判定的准确率,这是一种有效、简便的补充检查方法。

Objective：To evaluate the significance of additional 180-degree roll test（RT）in the determination of affected side in patients with horizontal semicircular canal benign paroxysmal vertigo（HSC-BPPV）.Method：One hundred and six patients with HSC-BPPV were performed the 90 degree RT.patients whose affected side cannot be determined by 90 degree RT were performed 180 degree roll test.Result：The affected side was determined by the 180 degree RT in 10 cases in which the lesion side cannot be determined by the 90-degree RT.Conclusion：The affected side of HSC BPPV was able to be determined by 180 degree RT when it not possible to be determined by 90 degree RT.180 degree RT is an effective and simple additional method.
