Abstract： 目的探讨螺旋CT多平面和曲面重建成像对面神经管显示的临床应用.方法对1具尸体头颅标本、2个颅骨标本及43例患者进行颞骨螺旋高分辨CT扫描,层厚1.0 mm、间距0.2 mm、螺距为1.然后进行冠状面、矢状面及斜面的多平面重建(MPR)和面神经管全程的曲面重建成像,对尸体标本解剖面神经管,并与其断面图像对比.结果CT图像所见与标本解剖一致,40侧正常耳的面神经管迷路段、水平段在轴面扫描图像上显示最优,面神经管垂直段在矢状面及斜面重建图像上显示最优,曲面重建能显示面神经管连续的全程.中耳乳突炎25耳中,面神经管水平段及垂直段有破坏者分别为6耳及5耳;先天性外耳道闭锁的16耳中,面神经管异常达10耳;外伤后面瘫的5耳中,3耳见有面神经管骨折.面神经管在螺旋CT多平面和曲面重建图像上的表现与临床手术所见相符.结论螺旋CT多平面和曲面重建成像技术有利于面神经管的显示及其病变的诊断.
