BACKGROUND
One of the merits of exoscopes, including ORBEYE, is that they are superior to a microscope in terms of ergonomic features. We report a case of dural arteriovenous fistula (dAVF) that was cured by direct surgery using the ergonomic advantages of ORBEYE.
CASE DESCRIPTION
A 78-year-old man was found to have dAVF of the anterior cranial fossa incidentally. We performed direct surgery via bifrontal craniotomy. Because the frontal sinus was large, we reserved the frontal bone-like eaves in order not to open the frontal sinus. The vertex of his head was sufficiently down to shift the frontal lobe downward with gravity. During surgery, we set the angle of the operative visual axis of ORBEYE approximately horizontal to avoid the reserved frontal bone. We performed a stable operation using ORBEYE in a comfortable posture.
CONCLUSIONS
ORBEYE facilitates ergonomic microsurgery, even under the eaves, with the angle of the operative visual axis approximately horizontal using gravity.
背景
包括 ORBEYE 在内的手术显微镜的优点之一在于其在符合人体工程学的特征方面优于显微镜。我们报告了一例使用 ORBEYE 的符合人体工程学优势直接手术治疗的硬脑膜动静脉瘘（dAVF）。
病例描述
一名 78 岁男性偶然发现前颅窝动静脉瘘。我们通过额部开颅手术直接进行治疗。由于额窦较大，我们保留了类似额骨的屋檐，以避免打开额窦。他的头顶足够低，重力可使额叶向下移动。手术中，我们将 ORBEYE 的手术视轴角度设置为近似水平，以避免保留的额骨。我们使用 ORBEYE 在舒适的姿势下进行了稳定的手术。
结论
ORBEYE 即使在屋檐下，通过将手术视轴角度设置为近似水平并利用重力，也可方便地进行符合人体工程学的微创手术。
