Abstract：
Idiopathic bilateral facial nerve palsy is a rare condition and presents a diagnostic and prognostic challenge. Specifically, when bilateral nerves are damaged, it is difficult to predict the prognosis. We showcase the usefulness of contrast-enhanced magnetic resonance imaging (MRI) by providing information about localization and severity of degeneration of facial nerve. A 70-year-old Japanese man presented with bilateral simultaneous facial nerve palsy of House-Brackmann Grade VI on both sides. Contrast-enhanced MRI revealed bilateral intensity enhancement of intratemporal facial nerves. The signal intensity was higher on the left side than on the right side. Facial nerve decompression was performed on the left side. The left facial nerve palsy was finally improved eight months after the onset, while the right side was improved just under two months after the onset. Contrast-enhanced MRI for facial nerve palsy can provide valuable information for the evaluation of damaged facial nerves. In our patient\'s case, it was useful as a prognostic predictor of bilateral facial nerve palsy.
摘要：
特发性双侧面神经麻痹是一种罕见的疾病，对诊断和预后提出了挑战。具体来说,当双侧神经受损时，很难预测预后。我们通过提供有关面神经变性的定位和严重程度的信息来展示对比增强磁共振成像（MRI）的有用性。一名70岁的日本男子在两侧同时出现House-BrackmannVI级的双侧同时面神经麻痹。增强MRI显示颞内面神经双侧强度增强。左侧的信号强度高于右侧。左侧行面神经减压术。左面神经麻痹在发病8个月后终于好转,而右侧在发病后不到两个月就有所改善。面神经麻痹的增强MRI可以为面神经损伤的评估提供有价值的信息。在我们病人的情况下，它可作为双侧面神经麻痹的预后预测因子。
