A thorough understanding of the orbit, structures within it, and complex spatial relationships among these structures bears relevance in a variety of neurosurgical cases. We describe the 3-dimensional surgical anatomy of the orbit and fragile and complex network of neurovascular architectures, flanked by a series of muscular and glandular structures, found within the orbital dura.

This study aimed to investigate the application of 3-dimensional computed tomography angiography (3D-CTA) for defining cavernous sinus aneurysms and intradural aneurysms involving the internal carotid artery around the anterior clinoid process. ⋯ The virtual line between the inferior border of the anterior clinoid process and the tuberculum sellae on 3D-CTA indicates the proximal dural ring of the internal carotid artery. This line helps differentiate cavernous sinus aneurysms from intradural aneurysms involving the internal carotid artery around the anterior clinoid process.

Bone cement augmentation procedures (vertebroplasty and kyphoplasty) are the primary treatments for osteoporotic vertebral compression fracture (VCF). However, these procedures are associated with various problems resulting in subsequent fracture. The purpose of this study was to evaluate the spinal instability factors related to subsequent fracture after vertebral augmentation procedures. ⋯ Predictive scores can be calculated and used to predict the possibility of subsequent fracture according to scores. Group D showed the highest predictive scores and will need more preventative treatment.
