Impact of BrainLab VectorVision Infrared-Based Neuronavigation on Surgical Outcomes in Intracranial Meningioma Patients: A Retrospective Study.

BACKGROUND The BrainLab VectorVision neuronavigation system is an image-guided, frameless localization system used intraoperatively, which includes a computer workstation for viewing and analyzing operative microscopic images. This retrospective study aimed to evaluate the use of the BrainLab VectorVision infrared-based neuronavigation imaging system in 80 patients with intracranial meningioma removed surgically between 2013 and 2023. MATERIAL AND METHODS Data were retrospectively collected from 36 patients with convexity meningioma and 44 patients with parasagittal meningioma between 2013 and 2023. The surgical operation of 40 of these patients was performed with the help of neuronavigation, while the other 40 were performed without neuronavigation. Demographic data, preoperative and postoperative radiologic images, craniotomy measurements, surgical complications, and operative times of patients with and without neuronavigation were analyzed. RESULTS Using neuronavigation significantly increased surgery duration (P=0.023). In 6 patients without the use of neuronavigation, the craniotomy had to be enlarged and this resulted in superior sagittal sinus (SSS) damage (P=0.77, P=0.107). Patients for whom neuronavigation was used did not experience any sinus damage and did not require craniotomy enlargement. Postoperative epidural hematoma (EH) developed in 9 patients without navigation, whereas it developed in only 1 patient with navigation (P=0.104). Residual tumors were less common in patients using navigation (P=0.237). CONCLUSIONS The use of neuronavigation allows the incision and craniotomy to be reduced in size. Intraoperatively, it allows the surgeon to master the boundaries of the tumor and surrounding vascular structures, reducing the risk of complications. These results suggest that neuronavigation systems are an effective ancillary in meningioma surgery.
