| 摘 要： | 目的 :针对中颅窝手术进路 ,以面神经裂孔为标记 ,对内听道的毗邻结构进行测量 ,为临床手术操作提供应用解剖学基础。方法 :采用甲醛固定的头颅标本 2 4具 (4 8侧 ) ,分别暴露棘孔、岩浅大神经、岩浅小神经、面神经裂孔和弓状隆起 ,并对其相互之间的位置关系进行测量。结果 :8.3%面神经迷路段和膝状神经节骨管型缺如 ,面神经裂孔到膝神经节的距离变异较大。结论 :该研究提供的测量数值 ,对临床进行中颅窝手术进路的内听道定位有较大的参考价值。 |

| Abstract: | Objective:To provide anatomical basis for operation of internal auditory meatus(IAM). Correlation structures with IAM were measured according to sign of hiatus of facial nerve.Method:These structures include spinous foramen, superficial geater petrosal nerve, superficial lesser petrosal nerve, hiatus of facial nerve were measured on 24 wet cranial bone (48 sides).Result: It is demonstrated that 8.3 % geniculate ganglion and labyrinth segment of facial nerve Variation which distance from hiatus of facial nerve to geniculate ganglion is distinct.Conclusion:Our data will be very holpful for location of IAM during operation via middle cranial fossa approach. |
