摘　　要：目的 探讨多层螺旋CT面神经管曲面重建图像的解剖与临床应用.方法 选择2010年1-11月收治的面部神经疾病患者50例作为研究组,50例面部神经正常者作为对照组.采用多层螺旋CT对患者进行扫描,扫描将眼眶上缘至外耳道下缘连线作为水平线,范围从乳突下缘至颞骨岩部上缘,将获得的数据在Wizard工作站中进行重建.所有测量数据均为两位以上医生的测量结果 的平均值.结果 对照组面神经管均可以在一幅图像中清晰地显示出来,显示率为100.00%（50/50）,且各段数据可以准确测量得到;轴向重建、冠状位重建和矢状位重建三个方向测量的结果 比较,迷路段、水平段和垂直段的长度和直径的差异均无统计学意义（P＞0.05）,且第一弯曲角度和第二弯曲角度的差异均无统计学意义（P＞0.05）;与对照组比较,研究组不同面部神经疾病患者的显示率均明显下降,差异均有统计学意义（P＜0.05）.结论 多层螺旋CT曲面重建技术对面部神经疾病的诊断具有十分重要的临床意义,值得推广应用.Objective To probe into the anatomy and clinical application of the facial nerve canal surface by multislice spiral CT image curved planar reformation. Methods Fifty patients with facial nerve disease were selected as study group from January to November in 2010, 50 healthy subjects were selected as control group, using models of multislice spiral CT scan for the patient, scanning from the upper edge of the orbital under external auditory canal edge of the connection as a horizontal line, ranging from the lower edge of mastoid process to the petrous bone on the edge of the data obtained in the Wizard workstation reconstruction. All the measurements were more than two measurements of the average physician. Results Normal facial nerve canal in control group could be displayed clearly in an image, display rate was 100.00%（50/50）, and the segment data could be accurately measured; axial reconstruction, reconstruction of coronal and sagittal reconstruction of the three comparison of measured direction, fan sections, horizontal and vertical segments of the length and diameter were not significantly different （P〉0.05）, and the first and second bending angle of bending angle was no significant difference （P 〉 0.05 ）. Compared with control group, the patients with vascular disease in study group showed significantly decreased rate, the difference was significant （P 〈 0.05）. Conclusion Curved planar reformation of multislice spiral CT diagnosis of facial nerve canal disease has great clinical significance, should be widely applied.
