本研究的目的是通过钆增强磁共振成像（Gd-MRI）研究特发性周围性面神经麻痹（IPFP）患者面神经受累的发生率，并讨论其定位和增强模式。本研究共纳入13例IFPF患者（9例女性，4例男性）。进行地形图检查和肌电图（EMG）检查，并进行MRI检查。10名受试者的头部MRI采取非器质性病理作为对照组。13条麻痹面神经中12条增强后有强化。对照组2条面神经强化。我们发现面神经的增强与恢复时间之间存在相关性。强化组从面瘫发作到恢复的平均时间为14周，而无强化组为6周。所有患者面神经功能均完全恢复。我们的结论是，对比度增强的麻痹面神经可以是一个神经炎症的放射学迹象，并可能表明一个长期的恢复。(C)2003年爱思唯尔科学公司All rights reserved.
The aim of this study was to investigate the prevalence of facial nerve involvement with gadolinium-enhanced magnetic resonance imaging (Gd-MRI) in patients with idiopathic peripheral facial palsy (IPFP), and to discuss the localization and the pattern of enhancement. A total of 13 patients (9 female, 4 male) with IFPF were included in this study. Topographic tests and electromyography (EMG) were performed, and MRI was taken. Ten subjects whose cranial MRIs were taken for nonorganic pathology served as the control group. Twelve of 13 paralytic facial nerves had enhancement on postcontrast images. Two facial nerves of the control group demonstrated enhancement. We found a correlation between the enhancement of the facial nerve and the time for recovery. The average time from the onset of facial palsy to the recovery in patients with enhancement was 14 weeks, whereas it was 6 weeks in patient with no enhancement. Finally, all patients had complete recovery of the facial nerve function. We concluded that contrast enhancement of the paralytic facial nerve can be a radiological sign of a neural inflammation and may indicate a prolonged recovery. (C) 2003 Elsevier Science Inc.
