目的 :探讨急性面神经炎 (Bell麻痹 )患者的面神经传导速度与病程及预后的关系。方法 :对 6 8例不同病程的Bell麻痹患者行健、患侧面神经传导速度检查 ,并和 10例正常对照组进行比较。结果 :面神经传导速度 :病程 <7天的患者的患侧与健侧及对照组比较无明显差异 (P >0 0 5 ) ;病程 >7天患侧与健侧及对照组比较有极显著性差异 (P <0 0 0 1) ;病程 1个月内完全恢复者患侧与健侧及对照组比较无显著性差异 (P >0 0 5 ) ;病程 2个月、6个月内完全恢复和未完全恢复者患侧与健侧及对照组比较有显著性差异 (P <0 0 1) ;不同转归组两两比较有显著性差异 (P <0 0 1)。面神经传导速度减慢程度越重 ,面神经功能临床恢复所需要的时间越长。结论 :Bell麻痹患者患病一周后的面神经传导速度可作为评价面神经功能及预后的一项可靠指标。
Objective: To investigate the relationship between facial nerve conduction velocity, duration of disease and prognosis in patients with acute facial neuritis (Bell’s palsy). Methods: A total of 68 healthy Bell palsy patients with different course of disease were examined for lateral nerve conduction velocity and compared with 10 normal controls. Results: The facial nerve conduction velocity: the duration of disease <7 days in patients with contralateral and contralateral side and the control group no significant difference (P> 0.05); duration of> 7 days in the ipsilateral and contralateral and control groups were significantly different (P <0.01). There was no significant difference between the affected side and contralateral side and the control group within 1 month of course of disease (P> 0.05); the course of disease recovered completely within 2 months and 6 months There was a significant difference between the two groups (P <0.01) in different outcome group and those in control group and those in incomplete recovery group (P <0.01). The more severe the slowing of facial nerve conduction velocity, the longer the time required for clinical recovery of facial nerve function. CONCLUSIONS: The facial nerve conduction velocity after a week of onset in patients with Bell palsy can be used as a reliable indicator of facial nerve function and prognosis.
