Performing microsurgery with the support of navigation in falcine meningioma management shows significant impacts in short and middle-time follow-up, including unilaterally skull opening with smallest and nearest skin incision, lessen the surgical duration, limit blood transfusion and prevent tumours from recurrence. Sixty-two falcine meningioma patients treated by microoperation applying neuronavigation were enroled from July 2015 to March 2017. Patients are evaluated before and 1 year after surgery according to The Karnofsky Performance Scale (KPS) for comparison. Histopathology: the most common was fibrous meningioma with 32.26%; meningothelial meningioma was 19.35% and transitional meningioma was 16.13%. KPS I before surgery was 6.45% and after was 83.87%. KPS III who needed assistance in activities preoperation was 64.52% and postoperation was 1.61%. After surgery, there was no disabled patient. All patients were followed up a year after surgery and received MRI to evaluate the recurrence. After 12 months, there were three recurrent cases, accounted for 4.84%. Microsurgery under neuronavigation help brings significant improvement in patient's functional abilities and low recurrence of falcine meningiomas within 1-year post-surgery. Further studies with large sample size and longer follow-up duration should be performed to reliably evaluate safety and effectiveness of microsurgical neuronavigation in the management of the disease.
