BACKGROUND: Anterior skull base meningiomas (ASBMs) account for about 10% of meningiomas. Bifrontal craniotomy (BFC) represents the traditional transcranial approach to accessing meningiomas in these locations. Supraorbital craniotomy (SOC) provides a minimally invasive subfrontal corridor in select patients. Here, we present our series of ASBM accessed by SOC and BFC by a single surgeon to review decision-making and compare outcomes in both techniques. METHODS: Thirty-three patients were identified with ASBM. Age, tumor characteristics, presenting symptoms, postoperative complications, and outcomes were analyzed. RESULTS: Bifrontal and SOC were performed in 13 and 20 patients, respectively. Mean follow-up time was 98.4 months. Patients undergoing SOC had smaller tumor size, located farther from the posterior table of frontal sinus, had less peritumoral edema, and decreased length of stay compared to patients undergoing BFC. Extent of resection was slightly better with BFC (99.8%) compared to SOC (91.8%), although this difference did not reach statistical significance. Recurrence-free survival and rate of re-do surgeries were not different between two groups. BFC was associated with higher rates of postoperative encephalomalacia. CONCLUSION: SOC provides an excellent surgical option for ASBMs providing comparable extent of resection, minimal manipulation of brain, and excellent cosmetic outcomes for patients. The patient selection is key to maximize the benefits from this approach.
背景:前颅底脑膜瘤(ASBM)约占脑膜瘤的10%。双额开颅术(BFC)是传统的经颅入路,用于处理这些部位的脑膜瘤。眶上开颅术(SOC)为部分患者提供了微创的额下通道。在此,我们展示由同一位外科医生采用SOC和BFC治疗的一系列ASBM病例,以回顾决策过程并比较两种技术的疗效。 方法:共确定33例ASBM患者。分析患者的年龄、肿瘤特征、症状表现、术后并发症及疗效。 结果:分别有13例和20例患者接受了双额开颅术和眶上开颅术。平均随访时间为98.4个月。与接受BFC的患者相比,接受SOC的患者肿瘤体积较小,距离额窦后板较远,瘤周水肿较轻,住院时间较短。BFC的切除范围(99.8%)略优于SOC(91.8%),但差异无统计学意义。两组的无复发生存率和再次手术率无差异。BFC术后脑软化发生率较高。 结论:SOC为ASBM提供了一种极佳的手术选择,其切除范围相当,对脑的操作 minimal,且对患者有极佳的美容效果。患者选择是最大化该方法益处的关键。 (注:原文中“minimal manipulation of brain”处“minimal”拼写有误,应为“minimized”,译文按正确理解翻译)
