We developed and tested a new, angled rigid endoscope as a tool for performing continuous visual monitoring during microsurgery. The shaft of the scope is angled 110 degrees at its midportion using a prism. We used the scope continuously in 30 cases including 15 pituitary tumours, 7 brain tumours, 7 cerebral aneurysms, and one hemifacial spasm. For pituitary tumours the tip of the scope was positioned in the sphenoid sinus or in the cavity formed by tumour removal; for cerebral aneurysms it was placed behind the parent artery or the aneurysmal neck. Image quality was acceptable for intraoperative monitoring. In no case did the neuroendoscope have a deleterious impact on th e proper function of the microscope or surgical instruments. This angled rigid scope was more effective for intraoperative monitoring than conventional straight scopes.
我们研发并测试了一种新型的、带角度的硬质内窥镜，作为在显微手术期间进行连续视觉监测的工具。该内窥镜的镜身中部通过棱镜呈110度角。我们在30例手术中持续使用了该内窥镜，其中包括15例垂体瘤、7例脑肿瘤、7例脑动脉瘤和1例半面痉挛。对于垂体瘤，内窥镜尖端置于蝶窦或肿瘤切除后形成的腔内；对于脑动脉瘤，将其置于载瘤动脉或动脉瘤颈部后方。图像质量对于术中监测而言是可接受的。神经内窥镜在任何情况下均未对显微镜或手术器械的正常功能产生有害影响。这种带角度的硬质内窥镜在术中监测方面比传统的直管内窥镜更有效。
