Abstract：
OBJECTIVE: Since its introduction in the 1950s, the microsurgical paradigm has revolutionized neurosurgery. New technologies have been introduced over the years trying to overcome limits of the classical operating microscope. The recently developed 3D exoscopes represent a potential new paradigm for micro-neurosurgery. We analyzed our own experience with a 4 K-3D exoscope in a series of pediatric brain tumors to verify its advantages and limitations in comparison to the operating microscope and in light of the literature.
METHODS: Twenty-five pediatric patients with brain tumors underwent surgery at our Institute; the population has been analyzed and described. A score to evaluate the exoscopes and compare it to the operating microscope was considered and postoperatively applied to each single case.
RESULTS: The exoscope appears to be at least comparable to the operating microscope (OM) in all analyzed aspects. In the case of deep-seated or fourth ventricle tumors, the exoscope seems to be superior to the microscope. A surgeon-dependent learning curve is necessary for neurosurgeons to be confident with the exoscope.
CONCLUSIONS: Exoscopes appear to be as safe and effective as operating microscopes in pediatric neuro-oncological surgery. They have some advantages that make them superior to microscopes, particularly regarding surgeon ergonomics and fatigue, visual field qualities, and higher choice of intraoperative viewing angles.

摘要：
目标：自1950年代推出以来，显微外科模式彻底改变了神经外科。多年来引入了新技术，试图克服经典手术显微镜的局限性。最近开发的3D手术镜代表了微神经外科的潜在新范例。我们在一系列小儿脑肿瘤中使用4K-3D外镜分析了自己的经验，以验证其与手术显微镜和文献相比的优势和局限性。
方法：25例小儿脑肿瘤患者在我们研究所接受了手术；对人群进行了分析和描述。考虑了评估外镜并将其与手术显微镜进行比较的评分，并在术后将其应用于每种情况。
结果：在所有分析方面，外镜似乎至少与手术显微镜（OM）相当。在深部或第四脑室肿瘤的情况下，外镜似乎优于显微镜。外科医生依赖的学习曲线对于神经外科医生对外镜充满信心是必要的。
结论：在小儿神经肿瘤外科手术中，外诊镜与手术显微镜一样安全有效。它们有一些优势，使它们优于显微镜，特别是关于外科医生人体工程学和疲劳，视野质量，术中视角的选择更高。
