Abstract
Objective: The preliminary clinical experience of the neuronavigator-guided ventriculoscopy techniques used in the treatment of intraventricular cysts was reported and the impact of the combined use of these techniques for the neuroendoscopic surgery was discussed. Methods : Under the guidance of neuronavigation, surgical plan including optimal skin incision and approach was conducted. During the surgical operation, the trajectory of ventriculoscopy was monitored and guided in real time and dynamically by neuronavigation system. The cysts were fenestrated successfully by using endoscope in three cases. Results: All patients postoperatively achieved satisfied effects without mortality and serious complications such as hemorrhage, CNS infection and focal neurological deficits . Two cases representing temporary fever were diagnosed with aseptic meningitis, which is mainly related to the manipulation in the ventricle. Conclusion : The ventriculoscopic neurosurgery for intraventricular cysts possesses the advantages of invasion and good surgical result. The combined application of ventriculoscopy and neuronavigation should be more accurate, effective, and safe, especially for overcoming the topographic varitation caused by intraventricular pathologies. Neuronavigator-guided ventriculoscopy techniques will be widely used in the field of minimally invasive microneurosurgery. Paragraph Headings: 1. Methods 1.1.

Outcome afterNeuronavigator-guided endoscopic treatment of three patients with intraventricular cysts Figures: 1. The SureTrak Universal Instrument Adapter system is compled to the ventriculoscopy 2. The optimal approach, including entrance point, target point, and surgical trajectory, is determined by the surgeon on the monitor screen preoperatively. 3. After calibration and verification, the position of the tip of the ventriculoscopy with SureTrak adapter in relation to the lesion is displayed, allowing the surgeon to determine the entrance point and orientation 4. Comparion to the preoperative CT scan, MRI showed the volume of the cyst reduced 70%, postoperatively
