The Evolution of Neuroendoscopy Guided by Head-mounted Mixed Reality Technique Navigation System in Neurosurgery

The pineal region and brainstem tumors are located at the central position of the cranial cavity, surrounded by important neural structures and venous systems, leading to challenges in preoperative diagnosis, adding uncertainty and complexity to treatment. For a long time, surgical treatment of pineal region and brainstem tumors has been one of the most challenging areas in neurosurgery. With the development of neuroendoscopy and virtual endoscopy technologies, how to convert complex three-dimensional bone, vascular, and neural images into virtual endoscopic images and how to combine virtual endoscopy with neuro-navigation for endoscopic skull base surgery to provide high-quality guidance images for surgery has become an urgent new research issue. The project team plans to develop a neuroendoscopy combined with a wearable mixed reality glasses navigation system, integrating the advantages of wearable glasses and existing surgical navigation systems. This study aims to evaluate the role of mixed reality navigation systems in improving total resection and reducing major complications in patients with pineal region and brainstem tumors, as well as shortening surgical times.
