Can meningioma surgery achieve complete resection?

    In most cases, meningioma surgery can achieve complete resection. However, total removal may not be possible if the tumor is located in a special position or has complex characteristics. If any abnormalities are present, timely medical consultation is recommended. Detailed explanations are as follows:

    In most cases, meningioma surgery can achieve complete resection. Meningiomas are common benign intracranial tumors, characterized by slow growth, clear boundaries, and often a complete capsule. These features make meningiomas easily identifiable and separable during surgery, thus enabling complete removal.

    However, total resection may not be achievable if the tumor is located in a special position, invades critical structures, or has complex characteristics. When meningiomas are located adjacent to critical structures such as the superior sagittal sinus, straight sinus, or torcular herophili, the surgeon may choose to leave behind part of the tumor tissue to avoid damaging these essential structures. Additionally, in cases of malignant meningiomas or multiple meningiomas with complex tumor characteristics, total resection may also be unfeasible. In such situations, the surgeon will weigh the surgical risks against the extent of tumor removal and choose the most appropriate surgical approach.

    Meningiomas are benign and grow slowly; even if some tumor tissue remains, it does not necessarily lead to rapid recurrence or deterioration. The tumor can be managed through close monitoring of disease progression, regular follow-up examinations, and other adjuvant treatment methods, ensuring the patient's health and quality of life.
