[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.


METHODS
Three hundred and five patients were undergone endoscopic surgery using IGNS. The detailed information 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 evaluate the effect of IGNS.


RESULTS
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 reinforced the operators self-confidence, increased the patients' safety with the almost same time as that of routine endoscopic surgery (ESS).


CONCLUSIONS
IGNS could elevate the effectivity and security of ESS, indicating it's a valuable tool in deal with complex endoscopic endonasal surgery.
