| 摘 要： | 目的探讨Bell面瘫、Ramsay-Hunt综合征的MRI表现。资料与方法对10例经临床确诊为Bell面瘫或Ramsay-Hunt综合征的患者,分别测量增强后患侧面神经迷路段、前膝部、鼓室段及乳突段信号强度,并与健侧面神经信号强度进行比较,判断面神经病变范围及其强化程度。10例患者患侧、健侧各得到38个节段的信号值。结果 10例增强后测得患侧面神经迷路段、前膝部、鼓室段及乳突段信号强度值高于健侧,差异具有统计学意义(P<0.01)。其中患侧高于健侧者为26个节段(68.4%,),包括面神经迷路段4个节段(4/26,15.4%),前膝部9个节段(9/26,34.6%),鼓室段6个节段(6/26,23.1%)及乳突段7个节段(7/26,26.9%)。结论增强MRI对诊断Bell面瘫、Ramsay-Hunt综合征有重要帮助。

| Abstract: | Objective To investigate MRI findings in Bell palsy and Ramsay Hunt syndrome.Materials and Methods Contrast-enhanced MRI was obtained in 10 patients,including 7 cases of Bell palsy and 3 cases of Ramsay Hunt syndrome.The MR signal intensities of 38 segments of each facial nerve were obtained,which contained labyrinthine segment,geniculate segment,segment in cavum tympani and segment in mastoid process.Results Post-contrast MRI images showed the signal intensities of 26 segments of affected facial nerve were... |
