To analysis the therapeutic effect of modified vertical incision combined with supratentorial approach and dynamic traction for microresection of falcate tentorial meningioma.

The clinical data of 70 patients with falcate tentorial meningioma who underwent primary operation in the Neurosurgery Department of the First Affiliated Hospital of Xinjiang Medical University from January 2013 to January 2020 were analyzed retrospectively. Among them, 35 patients adopted the modified straight incision combined approach and 35 patients adopted the single approach. The general data (gender, age, tumor size and tumor location) of the two groups were collected, and the differences of operation related factors (bleeding volume, operation time, deep vein injury, tumor resection degree), length of hospital stay and postoperative complications between the two groups were analyzed.

There was no significant difference of general information between the two groups, and they were comparable. The patients were followed up for 6 months, there was no significant difference in the amount of bleeding, operation time, incidence of postoperative complications and length of hospital stay between the two groups (P>0.05). The KPS score of the modified straight incision combined approach group at 1 week and 6 months after operation was significantly higher than that of the single approach group (P<0.05). There were significant differences in deep vein injury, tumor resection rate and cortical blindness between the modified straight incision combined approach group and the single approach group (P<0.05).

For falcate tentorial meningioma, the improved straight incision combined with superior and inferior dural approach combined with microscope "conical field" and "dynamic traction" technique can effectively reduce iatrogenic brain injury, obtain a multi-angle and wide range of deep surgical fields. The incidence of postoperative complications is low, the hospital stay is short, and the postoperative rehabilitation effect is good.
