PURPOSE
To compare the results of video head impulse test (vHIT) and caloric testing (CT) in patients with vestibular migraine (VM) and Ménière's disease (MD) and to investigate the relationship between these two tests.
METHODS
Patients with definite unilateral MD and VM were included in the study. All patients underwent both vHIT and CT. The vestibulo-ocular reflex (VOR) gains of lateral semicircular canals and saccadic waves in vHIT and the canal paresis factor for the CT were examined.
RESULTS
CT was found abnormal in 39 (66.1%) patients with MD and in 17 (34%) patients with VM, while abnormal gain of the lateral canal was obtained in 23 MD (39%) patients and 9 (18%) VM patients. In all, 11.9% of patients with an abnormal vHIT had a normal CT, whereas 33.9% of those with an abnormal CT had a normal vHIT.
CONCLUSION
Loss of VOR detected by caloric testing is more common and severe in MD than VM. Although vHIT is useful and can give complementary information, vestibular testing with the caloric test still seems more sensitive for detecting hVOR pathology.
目的
比较前庭性偏头痛（VM）和梅尼埃病（MD）患者视频头脉冲试验（vHIT）和冷热试验（CT）的结果，并探讨这两种检查的关系。
方法
本研究纳入了明确单侧 MD 和 VM 的患者。所有患者均行 vHIT 和 CT 检查。检查了 vHIT 中水平半规管的前庭眼反射（VOR）增益和扫视波，以及 CT 的管麻痹因素。
结果
CT 检查发现 39 例 MD 患者（66.1%）和 17 例 VM 患者（34%）异常，23 例 MD 患者（39%）和 9 例 VM 患者（18%）出现水平半规管增益异常。异常 vHIT 患者中有 11.9%的 CT 正常，而异常 CT 患者中有 33.9%的 vHIT 正常。
结论
与 VM 相比，MD 患者的冷热试验检测到的 VOR 损失更常见且更严重。尽管 vHIT 有用且可以提供补充信息，但通过冷热试验进行的前庭检查似乎对检测 hVOR 病理学更敏感。
