Microsurgical resection of giant olfactory groove meningiomas through fronto-basal interhemispheric approach

目的探讨经额底前纵裂入路显微手术切除巨大型嗅沟脑膜瘤的手术方法及疗效。方法回顾性分析2018年2月至2020年2月经额底前纵裂入路显微手术切除的10例巨大型嗅沟脑膜瘤的临床资料。结果按Simpson手术切除标准分级:Simp⁃son分级Ⅰ级切除1例,Ⅱ级8例,Ⅲ级1例。无手术死亡病例,术后无颅内感染及癫痫等并发症。术后病理检查确诊为良性脑膜瘤。术后随访8~30个月,未见肿瘤复发或病情加重病例。结论经额底前纵裂入路切除巨大型嗅沟脑膜瘤,效果良好。

Objective To investigate the clinical efficacy of microsurgery through fronto-basal interhemispheric approach for the patients with giant olfactory groove meningiomas.Methods The clinical data of 10 patients with giant olfactory groove meningiomas who underwent microsurgery through fronto-basal interhemispheric approach from February 2018 to February 2020 were retrospectively analyzed.Results According to Simpson surgical resection standard classification:Simpson gradeⅠresection was achieved in 1 patient,gradeⅡin 8,and gradeⅢin 1.There were no operative deaths.There was no postoperative complications such as intracranial infection and epilepsy.Postoperative pathological examination showed benign meningioma in all the patients.The follow-up ranged from 8 months to 30 months.There were no tumor recurrence or aggravation.Conclusions Microsurgery through fronto-basal interhemispheric approach is a good method for treatment of the patients with giant olfactory groove meningioma.
