The rabbits were immobilized according to the standard of X_knife before CT scanning. The interrelation of the silica gel tube and bony structures was analyzed, a nerve segment was selected, which could be localized according to the related bony structures as irradiation target. A radiosurgery treatment planning was performed on the selected nerve segment, its changes of pathology and ultrastructure were observed. Results: Base on the dissection, the rabbits' sciatic nerve was composed of the seventh lumbar nerve and first and second sacral nerves.

通过解剖分析兔坐骨神经主干的解剖位置和行径，选择照射靶点，放置硅胶管进行标记，按X_刀标准行CT扫描，从CT图像上分析硅胶管与荐骨和髂骨的位置关系，确定可以用骨性结构定位的神经段作为照射靶点，利用立体定向技术单次大剂量照射坐骨神经，观察其病理及超微结构变化。

Methods Twenty-two pieces of temporal bone were taken for this study. The mastoid cavity was opened, scutum removed,"bridge" broken down, posterior wall of external auditory canal abraded and the related anatomic structures were fully exposed. The distance between the origin of facial nerve canal and the anterior border of round window （ OOFNC-ABORW ）, between the highest point of the facial nerve canal and the bottom of posterior mastoid sinus,and between the stapes head and round window niche was measured under operating microscope.
