Objective : Navigation systems have been recently used in neurosurgical field for minimally invasive surgery . The author evaluates techniques and clinical experience of neuronavigation system in brain tumor surgery .
Clinical Materials and Methods : The author reviewed clinical and radiologic datas of 41 patients with brain tumor surgery using neuronavigation system during period between June 2003 and July 2005. The planning of the operative procedure was based on CT or MR-imaging using skin markers. In axial images the tumor contour was defined on the computer work station and transferred to a display. Preoperative and postoperative clinical and radiological status were reviewed to evaluate the efficacy of the neuronavigation aided surgery.
Results : Clinically , it was helpful in preoperative planning , deciding the site and location of craniotomy and judging the anatomic position of intracerebral lesion. The estimated registration error was 1.2mm . The most common pathologic diagnosis was meningioma.
Conclusion : Neuronavigation system provides an accurate and reliable means for localizing lesions with the brain and identifying anatomical structures .The aim of neurovavigation application for brain tumor surgery can be achieved by minimizing surgical morbidity and operation time.
