Meningiomas originate from the meninges and interstitial derivatives of the meninges, mostly from arachnoid cells, and can occur anywhere that contains an arachnoid component. The population incidence of meningioma is 2 per 100,000. It accounts for 19.2% of primary brain tumors in the same period, second only to glioma (40.49%). The occurrence of meningioma may be related to certain internal environmental changes and genetic variants, and is not caused by a single factor. It may be associated with cranial trauma, radiation exposure, viral infection, and combined bilateral auditory neuroma. Meningiomas are spherical in shape and have clear borders with brain tissue. Benign meningiomas grow slowly and have a long course, with an average of 2.5 years for early symptoms and up to 6 years for long ones. Depending on the location of the tumor, patients may have visual, visual field, smell or hearing impairment and limb movement disorder. In elderly patients, epilepsy is the first symptom. The treatment of meningioma is mainly surgical resection. In principle, complete resection and removal of the meninges and bone invaded by the tumor should be pursued in order to achieve radical treatment. Meningioma is an extra-parenchymal growth tumor, most of them are benign. If the tumor can be diagnosed early and operated before the tumor damages the surrounding brain tissues and important cranial nerves and blood vessels, it should be able to achieve complete resection. However, there are some advanced tumors, especially deep meningioma, which are huge and adhere to the nerves, blood vessels, brainstem and lower thalamus, or the nerves and blood vessels are not easy to be separated, in this case, total resection should not be performed reluctantly to avoid aggravating brain and cranial nerve damage and the risk of intraoperative hemorrhage, or even death or serious disability. It is advisable to limit the tumor to subtotal resection, reduce the volume of the tumor, supplemented by decompression surgery to reduce the pressure of the tumor on the brain, relieve the intracranial pressure and protect the vision. Or it can be treated by staged surgery. The surgical treatment of skull base meningioma (including pterygoid crest, rock slope, saddle node, and olfactory groove) has always been a key difficult and hot issue for neurosurgeons. The Department of Neurosurgery of Renaissance Hospital of Capital Medical University has treated dozens of patients with meningioma, including skull base meningioma, surgically in the past 1 year, and all of them have achieved very satisfactory results.
