The mainstay of treatment for tumors growing inside the head is surgical removal, but it is also important to distinguish whether the tumor is benign or malignant, as well as the basic shape of the tumor. Generally, for benign pituitary tumors, pituitary tumors are removed through the transnasal pituitary approach. For some convex benign meningiomas, they are removed mainly by craniotomy. In some specific cases, if some tumors are malignant, it is not only necessary to remove the tumors during surgery, but also necessary to cooperate with radiotherapy or even chemotherapy in the later stage of the integrated treatment, so as to kill the tumor cells as much as possible, and to reduce the corresponding recurrence and the chances of further progress. Therefore, for tumors growing in the head, it is important to first clarify which type of tumor and where it is growing. There are 24 surgical approaches to the cranial brain, so it is important to clarify which type of tumor and which surgical approach to take in order to achieve the best timing and treatment results for the patient.
