摘　　要：目的探讨利用三维CT重建技术进行内镜经鼻岩尖区手术的可行性与可靠性。方法选取100例行颅底区域连续扫描的CT检查者,寻找辨认解剖标志并测量相关两点间的空间距离。结果咽鼓管-视神经管、咽鼓管-破裂孔、咽鼓管-卵圆孔、咽鼓管-圆孔、视神经管-破裂孔、破裂孔-卵圆孔、视神经管-卵圆孔、颈内动脉与蝶窦或筛窦外侧壁交点-卵圆孔空间距离分别为(34.79±3.12)、(9.82±2.67)、(18.78±3.10)、(24.49±3.21)、(25.67±1.97)、(9.55±1.82)、(28.09±1.68)、(31.16±2.29)mm。不同性别、左右两侧数据差异无统计学意义。结论三维CT重建是研究内镜经鼻岩尖区手术应用解剖的可行、可靠的方法。利用三维CT重建技术测量得出的数据可作为内镜经鼻岩尖手术的参考。Objective To evaluate the feasibility and reliability of anatomic study using 3D CT construction in en- doscopic endonasal petrous apex operation. Methods The study was carried out on the CT continuous scanning images of skull base region in 100 cases to find and identify anatomic landmarks .Relative dimensional distances were measured. Results Dimensional distances were shown separately as such toms tubarius - optic nerve canal （ 34.79±3.12）mm, toms tubarius - foramen lacemm （9.82±2.67）mm,toms tubarius-foramen ovale （18.78±3.10）mm, et al.There were no significant differences between males and femals on the same side measurements, or between the lefts and rights on the same land markers distances. Conclusion The measurement data obtained from 3D-CT reconstruction can be used as a reference in trans nasal endoscopic petrous apex operation. Anatomic study using 3D CT reconstruction is feasible, reliable in such operations.
