Objective: to demonstrated the advantages of using a minimally invasive approach for surgical treatment of craniovertebral junction meningiomas.
Materials and methods: In Burdenko Neurosurgical Center between 2010 and 2018, 54 patients (12 males, 42 females) underwent surgical removal of craniovertebral junction meningiomas. Mean patient age was 57.8 years (30-82 years). Mean follow-up was 52.2 months (6-300 months). Patients were divided into 2 groups: Group I consisted of 38 patients operated with classic open surgical approach; Group II consisted of 16 patients who were operated with a minimally invasive surgical approach. Frankel, Karnofsky, VAS scales and MRI were used to evaluate patient outcomes. In both groups resection of the internal layer of the dural sheath was mandatory.
Results: Group II patient presented with a lower postoperative VAS score (mean difference between groups was 4 points), lower postoperative analgesic consumption, shorter hospital stay (mean hospital stay for group I - 6 days, for group II - 3 days) and with the same percentage of total resection and Frankel score.
Conclusions: Minimally invasive surgical approach for treatment of craniovertebral meningiomas permits total tumor resection with lower intraoperative soft tissue and muscle trauma based on postoperative MRI findings, lower postoperative pain, lower analgesic consumption and shorter hospital stay in comparison with the classic open surgical approach.
Keywords: Extramedullary tumor, craniovertebral junction, minimally invasive surgical approach
