睫状神经节的显微解剖学及其临床意义

Microanatomy and clinical significance of the ciliary ganglion

目的 探讨睫状神经节的显微解剖学特点 ,为球后麻醉提供详尽的解剖学资料。方法 采用 2 8例成人眼眶标本在放大 16倍显微镜下 ,对睫状神经节进行逐项解剖观测。结果 睫状神经节位于视神经与外直肌之间 ,呈长方形、椭圆形或三角形 ,分别测得睫状神经节与视神经、眼球后极、眶下缘以及眶上裂的平均距离。结论 熟悉此区域的显微解剖 ,术中可避免损伤重要的神经、血管结构 ,提出球后麻醉进针的深度宜为 32～ 36mm。

Objective To provide the anatomical knowledge for retrobular anesthesia. Methods Twenty-eight adult cadaveric heads were examined under 16 magnification, and the anatomical location of the ciliary ganglion as well as the local relation between this nerve ganglion and its peripheral structures surveyed. Results Ciliary ganglion was suited between optic nerve and lateral rectus. The shapes of ciliary ganglion was rectangle, oval or triangle, respectively. The distance from ciliary ganglion to the posterior wall of eyeball, inferior edge of orbit,optic nerve and superior orbital fissure were found respectively. Conclusion The vital nerves and vascularstructures can be protected in operation if one is familiar with the anatomy of ciliary ganglion. For retrobulabar anesthesia the injection depth should be 32～36 mm.
