OBJECTIVE
To investigate an effective method of quantitative analysis of the facial nerve and its adjacent structures on the basis of three-dimensional (3D) CT image reconstruction of the temporal bone.
METHODS
The inner structures of the temporal bone from CT images of 34 healthy adults were reconstructed. Precise measurement of the facial nerve and its adjacent structures were accomplished by using Able Software 3D-DOCTOR.
RESULTS
3D images of temporal bone structures, including facial nerve, tympanic annulus, cochleariform process, cochlea, semicircular canals, jugular fossa, and carotid artery, were reconstructed. Quantitative data of the facial nerve and its adjacent structures were analyzed, especially the detailed spatial relationships between the facial nerve and the surface of the mastoid process or tympanomastoid fissure.
CONCLUSION
3D reconstruction of CT images clearly displayed the detailed structures of the temporal bone. Quantitative data of the facial nerve and its adjacent structures are very useful for temporal bone surgery.
目的
基于颞骨的三维（3D）CT图像重建，研究一种对面神经及其相邻结构进行定量分析的有效方法。
方法
对34名健康成年人的CT图像中的颞骨内部结构进行重建。使用Able Software 3D-DOCTOR对面神经及其相邻结构进行精确测量。
结果
重建了颞骨结构的3D图像，包括面神经、鼓环、匙突、耳蜗、半规管、颈静脉窝和颈动脉。分析了面神经及其相邻结构的定量数据，特别是面神经与乳突表面或鼓乳裂之间的详细空间关系。
结论
CT图像的3D重建清晰显示了颞骨的详细结构。面神经及其相邻结构的定量数据对颞骨手术非常有用。
