眶上"锁孔"入路的内窥镜解剖学研究

目的 :研究眶上“锁孔”入路的内窥镜局部解剖学并测量有关解剖数据 ,为临床外科手术提供形态学参考信息。方法 :测量 10 0例成人颅骨标本额骨颧突距同侧和对侧前后床突的距离和角度 ;用手术显微镜和硬质内窥镜交替使用通过 2 5具成人尸头 ,探讨眶上“锁孔”手术入路 ,并测量颧突与颅内血管的距离和角度。结果 :通过使用不同角度窥镜和在不同解剖间隙内操作可达到Willis环双侧及鞍区、岩斜区。结论 :锁孔技术是一种微侵袭神经外科技术。解剖数据结果对于选择手术器械的长度有参考价值 ;窥镜辅助手术可达Wills环及鞍区、岩斜区 ,配合特殊手术器械可完成上述区域病变的治疗。

The supraorbital "keyhole" approach: a study of endoscopic anatomy

Objective:To study endoscopic anatomy of supraorbital keyhole approach.Methods:The distance and angle between the zygomatic process and anterior and posterior clinoid process of two sides.Twenty five adult cardaveric head specimens were studied with endoscope and surgical microscope alternatively via keyhole approach.Results:Willis circle and sella and petroclivus' region can be reached via the approach by using endoscope in different angles.Conclusion:The keyhole technique is a mini invasive neurosurgical technique.The anatomic data is valuable for clinical operation.Willis circle,sella region and petroclivus region can be reached via the supraorbital keyhole approach.Diseases located in the region can be treated via the approach.
