[Microsurgical treatment of tentorial meningiomas: a systematic review].

Tentorial meningiomas account for 3-6% of all intracranial meningiomas. Complexity of topographic and anatomical location along with variability of surgical approaches underscores the importance of investigating these tumors. A systematic review was conducted in accordance with the PRISMA 2020 guidelines. We enrolled the studies devoted to outcomes after microsurgical treatment between 1984 and 2024. Demographic characteristics, neuroimaging data and postoperative outcomes were estimated. A total of 18 studies were selected. There were 668 patients, mean age was 52.6 years (478 females, 190 males). Mean tumor diameter was 33±5.4 mm. Preoperative hydrocephalus was detected in 17.1% of cases. The rate of gross total resection was 78%, complication rate - 34.3%, mortality rate - 3.3%. Microsurgical resection is the gold standard for meningiomas. The purpose of surgery is safe resection of tumor while preserving neurovascular structures. Adjuvant therapy may be considered for small tumors or subtotal resection.
