Objective:

Neuronavigation is an extremely common and useful system in intracranial surgeries. It is used to determine the pre-operative incision, perform the most appropriate craniotomy, and provide intraoperative guidance. However, its use in meningioma surgery is controversial, and there is a dilemma whether it is necessary. This study was performed to determine the effect of neuronavigation in meningioma surgery.

Materials and methods:

Information related to pre-operative clinical evaluation and use of neuronavigation, neuroimaging, intraoperative tumor and surgical related information, and post-operative outcomes of 75 consecutive patients with meningiomas between January 2015 and 2020 were retrospectively collected. The values between groups were statistically compared.

Results:

There were no significant differences in pre-operative patient and tumor characteristics between the groups. In cases using neuronavigation, the mean operative time, craniotomy size, and blood loss during tumor resection were significantly lower, and post-operative hospital stay was shorter in these patients (p < 0.05). However, there were no differences in post-operative complications and clinical outcomes.

Conclusion:

The use of neuronavigation in meningioma surgery reduces blood loss during surgery, reduces the surgical time, and shortens the post-operative hospital stay. Thus, we conclude that the neuronavigation system is useful in meningioma surgery.
