Microsurgical treatment of parafalcine meningiomas: a retrospective study of 126 cases

OBJECTIVE: To discuss the diagnosis, operation methods, and clinical effects of parafalcine meningiomas. METHODS: The clinical and preoperative imaging characteristics, operative methods, and effects of operations of 126 cases of parafalcine meningiomas were respectively discussed. RESULTS: G1 resection was achieved in 13 cases, G2 in 105 cases, G3 in four cases, and G4 in four cases, with no deaths. Among these, there were 16 patients with dyskinesia of the contralateral extremities after surgery, but they recovered after several months. CONCLUSION: In order to avoid postoperative complications, we consider it vital to analyze the patients’ condition, the anatomy of venous drainage in by digital subtractional angiography, the relationship between tumor location and brain tissue according to MRI, and to remove the tumor in an adequately exposed surgical field.
