To investigate whether or not and how often there is otolith dysfunction in an acute attack of Ménière's disease.
Twenty-two definite cases of unilateral Ménière's disease diagnosed in accordance with the 1995 criteria of the American Academy of Otolaryngology-Head and Neck Surgery for Ménière's disease.
Subjective visual vertical (SVV) test was performed before, at, and after acute attacks on 22 patients with unilateral Ménière's disease who showed normal tilts of SVV before acute attacks.
Abnormal tilts of SVV.
Of 22 cases, 14 (63.6%) with unilateral Ménière's disease showed abnormal tilts of SVV in acute attacks. The tilts were toward the side of the affected ear in 13 (92.9%) of them. Abnormal tilts returned to normal within a few weeks after the acute attacks in 12 (85.7%) of the 14 cases with unilateral Ménière's disease.
Otolith dysfunction occurred in acute attacks in a considerable number of patients with Ménière's disease. Subjective visual vertical can be used as a good tool for the evaluation of otolith dysfunction at acute attacks in patients with Ménière's disease.
研究梅尼埃病急性发作时是否存在耳石功能障碍以及其发生频率。
22例单侧梅尼埃病确诊病例，依据1995年美国耳鼻咽喉 - 头颈外科学会梅尼埃病诊断标准确诊。
对22例急性发作前主观视觉垂直（SVV）测试正常倾斜的单侧梅尼埃病患者，在急性发作前、发作时及发作后进行主观视觉垂直测试。
主观视觉垂直的异常倾斜。
22例单侧梅尼埃病患者中，14例（63.6%）在急性发作时出现主观视觉垂直异常倾斜。其中13例（92.9%）的倾斜方向朝向患侧耳。14例单侧梅尼埃病患者中有12例（85.7%）在急性发作后数周内异常倾斜恢复正常。
相当数量的梅尼埃病患者在急性发作时出现耳石功能障碍。主观视觉垂直可作为评估梅尼埃病患者急性发作时耳石功能障碍的良好工具。
