The survival time after surgery for malignant meningioma is about 2-3 years, but it must be judged according to the actual situation, each patient is different. Theoretically, if the malignant meningioma is removed cleanly and smoothly, and if there are no postoperative complications, then basically, after some radiotherapy and chemotherapy, the disease is controlled and it is possible for the patient to survive for 3 years or even about 5 years. In some patients with malignant meningioma, there is a large residue of incomplete resection during surgery, and there are also certain complications during surgery, such as hemiplegia of limbs and long-term bed rest, etc. The survival time of patients after surgery is relatively short, some even about 1-2 months. Therefore, the actual situation should be judged according to the cleanliness of the meningioma removal and the recurrence of the tumor later on, as well as the smoothness of the surgery.
