The frontobasal approach remains a workhorse for removing large olfactory groove meningiomas. Removal of the orbital bar in addition to standard bifrontal craniotomy allows for additional basal exposure, minimising brain retraction and allowing early and direct access to both the vascular supply and dural origin of this tumour. Here, we describe a simple yet effective modification to the standard orbital bar osteotomy. It has the benefit of being simpler and faster with improved cosmesis compared with an osteotomy of the entire orbital bar. It also has the advantage of not requiring manipulation of the supraorbital nerves or intraorbital or periorbital dissection.
额底入路仍然是切除大型嗅沟脑膜瘤的常用方法。除标准双额开颅术外，去除眶缘可增加基底暴露，减少脑牵拉，并能早期直接进入该肿瘤的血管供应和硬脑膜起源部位。在此，我们描述一种对标准眶缘截骨术的简单而有效的改良方法。与整个眶缘截骨术相比，它更简单、快速，美容效果更好。它还具有无需处理眶上神经或进行眶内或眶周解剖的优点。
