Abstract Conclusion: The distribution of abnormal results is not uniform between different canals in each patient; the most frequent gain reduction is obtained for the posterior canal. Gain reduction reflects the disease duration and amount of hearing loss.
To test the hypothesis that the vestibulo-ocular reflex (VOR) evoked after stimulation of each semicircular canal behaves in a different manner in patients with unilateral definite Ménière's disease.
We studied the VOR evoked by rapid head-impulses in the plane of the 6 semicircular canals in 36 patients. It was evaluated with a video system that analyzes the head and eye velocity and the gain was the objective measure.
In 12 (33.3%) patients the examination of both ears was normal for all the semicircular canals, in 12 patients the results from the affected ear were abnormal in at least 1 of the semicircular canals, in 11 (30.5%) patients the results were abnormal in at least 1 of the semicircular canals in both the affected and unaffected ears, and in 1 (2.9%) patient the results were abnormal only in the unaffected ear. The most frequent abnormal result was obtained from the posterior canal of the affected ear and from the coupled superior canal of the unaffected ear. The distribution of abnormal findings was dependent on the disease duration and hearing loss.
摘要 结论：每位患者不同半规管间异常结果的分布并不均匀；后半规管出现增益降低最为常见。增益降低反映疾病持续时间和听力损失程度。
检验单侧确诊梅尼埃病患者在刺激每个半规管后诱发的前庭眼反射（VOR）表现各异这一假说。
我们研究了36例患者在6个半规管平面上由快速摇头诱发的VOR。通过一个分析头部和眼球速度的视频系统进行评估，增益是客观测量指标。
12例（33.3%）患者双耳所有半规管检查均正常，12例患者患耳至少有1个半规管结果异常，11例（30.5%）患者患耳和未患耳至少有1个半规管结果异常，1例（2.9%）患者仅未患耳结果异常。最常见的异常结果出现在患耳的后半规管和未患耳的配对上半规管。异常发现的分布取决于疾病持续时间和听力损失。
