[Application of an image navigation system in nasal endoscopic surgery in treatment of basicranial tumor]
Objective:
To investigate the therapeutic effects of the image navigation system in nasal endoscopic surgery in treatment of basicranial tumor.
Method:
Retrospective analysis was carried out in 17 patients with basicranial tumor who underwent nasal endoscopic resection via image navigation system. The accuracy of image navigation system, operation procedure time, curative effect and complications were analyzed and summarized to evaluate the effect.
Result:
The image navigation system provided an accurate anatomical localization 0.5-2.0 mm localization error (mean 1.2 mm). The operation procedure time was 1.5-3.0 h. Postoperative complications occurred in 3 of 17 patients including cerebrospinal fluid rhinorrhea and injury of sieve plate. Two patients recrudesce within half a year.
Conclusion:
The image navigation system in combination with a nasal endoscope is helpful in the resection of basicranial tumor with minimal trauma, increasing the curative effect and avoiding complications.
