Before a surgeon performs surgery on a glioma patient, he or she needs to develop a preoperative plan in order to achieve a better outcome. Today, we will talk about the advantages of preoperative planning and its development! Why do we need a pre-operative plan? 1.Limitations of traditional glioma resection Traditional glioma resection surgery mainly relies on the abnormal morphology of the tumor tissue, the difference in color and texture between the tumor and the normal brain tissue for the localization of the tumor and the delineation of the tumor resection boundary. For gliomas in the functional brain area, traditional surgery cannot well determine the spatial positional relationship between the tumor and the surrounding structures, thus leading to more complications and neurological deficits in patients after surgery. 2.The superiority of evolving preoperative planning In recent years, with the development of medical science and technology, neuronavigation technology and multimodal image fusion technology have been widely used in neurosurgery. These technologies can help the operator to develop a more appropriate preoperative surgical plan, locate the tumor more accurately during surgery, reduce unnecessary complications, and achieve maximum safety resection. Multimodal neuroimaging is integrated with neuronavigation technology, which is then applied to preoperative planning and intraoperative real-time image tracking. How to make a preoperative plan? First, in the preoperative planning, the multimodal neuroimaging information is integrated, and various imaging characteristics are presented on the same image, so that comprehensive and accurate information about the tumor lesion and normal brain tissue can be obtained. Then, the connection between the fused imaging information and the anatomical structure of the nervous system is established by computer technology, which calculates and displays the precise location of the lesion, as well as its spatial relationship with the surrounding important tissue structures (e.g., nerve conduction bundles, blood vessels, and important functional areas, etc.). Finally, based on this information, surgical strategies are developed to maximize tumor removal while ensuring patient safety. In addition to glioma surgery, this is also the case for the preoperative planning of other diseases in our department, which is the result of our years of efforts to practice the concept of “precision diagnosis and treatment”. All in all, preoperative planning can better help doctors determine the patient’s condition and formulate a surgical plan. Therefore, preoperative planning is essential in the surgical treatment of glioma.
