面肌痉挛与后颅窝容积相关性研究

Hemifacial Spasm and the Posterior Fossa Volume correlation

目的本研究的主要目的是探讨后颅窝的体积异常是否是导致面肌痉挛患者神经血管冲突并产生临床症状的倾向因素。方法我们使用MRI容量分析法分析了40例面肌痉挛患者和20例健康对照组,比较病例组与健康对照组的后颅窝,并用相应的统计方法进行统计分析。结果病例组平均后颅窝体积为(157.9±14.9)cm3,健康对照组后颅窝容积为(161.7±15.1)cm3,病例组后颅窝与健康对照组差异无统计学意义。结论本研究中面肌痉挛患者后颅窝及与临床血管压迫神经学说无明显相关性。MRI容积分析法可以很好地测量后颅窝体积。

Objective The purpose of this study is to investigate the volume of the posterior fossa is lead to abnormal facial nerve vascular conflict and patients with spasm generated the tendency of clinical symptom factors.Methods We used MRI capacity analysis to amalyze the methods of 40 patients spmptom factors and 20 cases of healthy controls,compared with healthy controls the case group of the posterior fossa,and the corresponding statistics statistical analysis.Results The average case group posterior fossa volume for （157.9±14.9）cm^3, healthy controls the posterior fossa capacity of （161.7 ± 15.1）cm^3, posterior fossa and healthy controls the case group difference was statistically significant.Conclusin The study patients with posterior fossa and simg spasm clinical blood vessels oppressive nerve no obvious relevance theory. MRI volume analysis can be measuring the posterior fossa volume.
