影像导航系统在复杂鼻内镜手术中的作用和评价

目的：对影像导航系统在复杂鼻内镜手术中的作用进行评价。方法：使用影像导航系统对305例行鼻内镜手术的患者进行导航。对导航系统的精确性，总的手术时间，术者的满意程度，以及术中、术后的并发症进行详细记录分析。结果：305例患者中有301例（98．7％）影像导航系统提供了误差0.5～2．0mm（平均1．2mm）的解剖定位。术者增强了自信心，提高了手术的安全因素。未见术中及术后并发症发生。总的手术时间和常规鼻内镜手术时间基本相同。结论：影像导航系统是处理复杂鼻内镜手术很有价值的工具。

Effect and evaluation of image guided navigation system in complex endoscopic endonasal surgery

Objective:To evaluate the effect of image guided navigation system (IGNS ) in complex endoscopic endonasal surgery.Method:Three hundred and five patients were undergone endoscopic surgery using IGNS.The detailed imformation and data including the IGNS accuracy,the operation procedure time, the operator's satisfaction degree and self-confidence, and the perioperative complication were analysed and summarized to evalute the effect of IGNS.Result:The operation procedures were successfully performed in all the 305 patients without perioperative complication. In 98.7% of the total operation IGNS provided an accurate anatomical localization less than 2 mm localization error (0.5-2.0 mm,mean 1.2 mm ).The application of IGNS reiforced the operator's self-confidence,increased the patients'safety with the almost same time as that of routine endoscopic surgery (ESS ).Conclusion:IGNS could elevate the effectivity and security of ESS, indicating it's a valuable tool in deal with complex endoscopic endonasal surgery.
