Immediate and long-term results of microsurgical resection of tentorial meningiomas

Aim. To optimize the choice of surgical approach based on the assessment of immediate and long-term results of microsurgical treatment of cerebellar meningiomas.
Materials and methods. Between 2019 and 2023 at the Department of Neurosurgery of the m.f. vladimirsky moscow Regional Research Clinical Institute, 24 patients with primary meningiomas of the cerebellum underwent microsurgical treatment. The ratio between women and men was 5:1, mean patient age was 51.5 years. mean tumor volume was 8.7 cm3. Neurological and neuroimaging data, information about concomitant disorders, surgical protocols, information on postoperative complications, functional outcomes, and catamneses of the patients were compiled.
Results. Total tumor resection was achieved in 22 (91.7 %) cases, subtotal in 2 (8.3 %) cases with grade I–II radicality per the Simpson classification. Deterioration and neurologic deficit were observed in 5 (20.8 %) patients. In 2 (8.3 %) patients, dysfunction of the abducens nerve was observed, in 3 (12.5 %) – impaired hearing or deafness, in 5 (20.8 %) – ataxia aggravation. postoperative complications developed in 2 (8.3 %) patients. No deaths were registered. grade 1 meningiomas were found in 22 (91.7 %) patients, grade 2 – in 2 (8.3 %) patients.
Conclusion. During microsurgical removal of tentorial meningiomas, optimal surgical approach takes into account the topographic and anatomical location of the tumor. This makes it possible to achieve safe and effective treatment with favorable functional outcomes.
