[Application of image-guided system in endoscopic sinus and skull base surgery].

ABSTRACT

Objective:To evaluate the applicative value of image-guided system in endoscopic sinus and skull base surgeries. Method:A total of 103 endoscopic surgical procedures were performed.All these procedures were conducted with the utilization of image-guided system, among which there were 92 cases of sinonasal-skull base surgery(including nasal sinuses resection of benign and malignant tumors involving skull base lesions, the cumulative orbital lesion resection of nasal sinus lesions, etc. ), 6 repair of cerebrospinal fluid leak, 3 pituitary adenoma resection, 2 traumatic neuropathy optic nerve decompression. Result:With the utilization of image-guided system, all patients had successful surgery without major and minor complications. The image-guided system provided high precision with short registration time. Conclusion:Image-guided system can help the surgeon to identify accurately the vital anatomic landmarks of sinus and skull base, improving surgical accuracy and safety as well as reducing or avoiding the intraoperative and postoperative complications.
