Common knowledge about brain glioma surgery

Gliomas generally grow in an infiltrative manner with no obvious boundary from normal brain tissue. Most are not limited to one cerebral lobe and penetrate deep into the brain tissue like fingers. Although complete removal is theoretically impossible with surgery, it is still recommended to remove the tumor as much as possible while preserving neurological function to reduce the difficulty of future treatment.

1. When early-stage brain gliomas are small in size and in the appropriate location, efforts can be made to completely remove them, but care must be taken not to damage nerve function.

2. When the brain glioma is located in the frontal lobe or temporal lobe, lobectomy can be performed. If the frontal lobe or temporal lobe tumor is extensive and cannot be completely removed, the frontal pole or temporal pole can be removed simultaneously for internal decompression.

3. If the tumor is located in the motor and speech areas, even if there is no obvious hemiplegia or aphasia, the tumor should be appropriately removed to avoid serious sequelae. At the same time, attention should be paid to preserving neurological function during removal.

4. If the glioma is located in the ventricle and causes cerebral infarction, the brain tissue can be cut from the non-functional area to enter the ventricle and remove the tumor as much as possible.

5. If the glioma is located in the thalamus or brain stem, except for small nodular or cystic ones that can be resected, shunt surgery is generally performed to relieve increased intracranial pressure.

Tips: The role of brain glioma surgery

The main purpose of surgical resection of glioma is to clarify the pathological diagnosis, reduce tumor volume and the number of tumor cells, improve symptoms and relieve symptoms of high intracranial pressure, prolong life and create opportunities for subsequent other comprehensive treatments, and find effective treatments.
