Insula glioma is a deep brain tumor, which is more troublesome to operate because it is not on the surface of the brain and there is middle cerebral artery and its branches traveling on its surface, and such patients are mostly referred to the ward specialized in glioma surgery. The insula is a degenerative lobe in the brain development, compared to the cortical functional areas, he does not have his own direct functions, but mainly some accessory functions, belonging to the limbic system, performing functions such as coordination, memory, connection, etc. The frontal, temporal and parietal lobes cover his surface and he plays an important role in coordinating the functions of these lobes. Because it is not the most active lobe in development, gliomas that occur in the insula are also predominantly low-grade gliomas. For a specialized glioma ward such as ours, glioblasts in the insula are rarely found, which correlates with his neurological inactivity. Despite the predominance of low-grade gliomas in the insula, it is difficult to achieve a true microscopic total resection due to its anatomical peculiarities. His surface is covered with the middle cerebral artery and its branches, and to cut more, it is necessary to hollow out the tumor little by little in the vascular crevices, which is like curling, and the curler must be accurately placed in the best position by force, and such work requires the most precision and perseverance.
