RESUMO
Objective:To analyze the clinical efficacy of resection of anterior skull base meningiomas via neuroendoscopic supraorbital keyhole approach. Methods:Twelve patients with anterior skull base meningiomas resected via neuroendoscopic supraorbital keyhole approach in Department of Neurosurgery, Huaihe Hospital of He'nan University from May 2020 to May 2022 were chosen. A retrospective analysis was performed on the clinical data of these patients. Results:Postoperative brain enhanced MRI showed resection degree of Simpson grading Ⅰ in 2 patients and Simpson grading Ⅱ in 10 patients. Pathological examination indicated meningiomas in all patients. All patients were followed up for 3 months-2 years, and no cerebrospinal fluid leakage or endoscopy-related complications occurred. Among the 6 patients with preoperative vision and visual field changes, 4 patients got obviously improved and 2 patients got slightly improved. The 2 patients with blunt headache before surgery had completely normal symptoms. Of the 2 patients with preoperative hyposmia, one recovered to normal and the other one got slightly improved in symptoms.Conclusion:Resection of anterior skull base meningiomas via neuroendoscopic supraorbital keyhole approach can effectively improve resection rate, reduce complication incidence, and improve cure rate.
