Among patients with facial nerve paralysis, significant difference was observed on three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging (3D-FLAIR MRI) between those with and without audio-vestibular disturbance. This MRI technique may contribute to elucidation of the pathology of Ramsay Hunt syndrome and Bell's palsy.
To evaluate the 3D-FLAIR MRI findings in patients who have facial nerve paralysis with and without audio-vestibular disturbance.
3D-FLAIR MRI was performed with and without gadolinium enhancement in 15 patients (5 men and 10 women) with unilateral facial nerve paralysis: 3 patients with Ramsay Hunt syndrome, 3 patients having facial nerve paralysis with hearing loss or vertigo without vesicles, and 9 patients with Bell's palsy.
Five of the six patients with audio-vestibular disturbance showed high signals in the inner ear on precontrast 3D-FLAIR. In comparison, among nine patients with Bell's palsy, only one patient showed high signals in the inner ear on precontrast 3D-FLAIR (p < 0.05).
在面神经麻痹患者中，三维液体衰减反转恢复磁共振成像（3D-FLAIR MRI）显示，有听觉前庭功能障碍和无听觉前庭功能障碍的患者之间存在显著差异。这种MRI技术可能有助于阐明拉姆齐·亨特综合征和贝尔麻痹的病理情况。
评估有和没有听觉前庭功能障碍的面神经麻痹患者的3D-FLAIR MRI表现。
对15例单侧面神经麻痹患者（5例男性和10例女性）进行了有无钆增强的3D-FLAIR MRI检查：3例拉姆齐·亨特综合征患者，3例有听力损失或眩晕但无疱疹的面神经麻痹患者，以及9例贝尔麻痹患者。
6例有听觉前庭功能障碍的患者中，5例在对比前3D-FLAIR上内耳显示高信号。相比之下，9例贝尔麻痹患者中，只有1例在对比前3D-FLAIR上内耳显示高信号（p<0.05）。
