The dura mater, a fibrous membrane protecting the brain and spinal cord, is prone to lacerations during spinal surgery, often leading to complications such as cerebrospinal fluid (CSF) leakage. Anatomical differences in the spinal dura mater, particularly in regions under high biomechanical stress, suggest that chronic inflammatory processes may compromise its structural integrity. This pilot study investigates the molecular and anatomical characteristics of the spinal dura mater, focusing on its response to inflammation and the challenges of surgical repair. ⋯ This pilot study aims to enhance our understanding of the inflammatory processes affecting the dura mater and their role in frequent lacerations during spinal surgery. Findings are expected to guide future clinical practices in dura repair strategies, potentially improving surgical outcomes and reducing complications related to CSF leakage.

In recent years, several studies have shown the presence of a linear correlation between the pelvic incidence (PI) and spondylolisthesis. However, no study has attempted to investigate a potential association between facet sagittal angle and spinopelvic parameters, especially PI in the normal population. ⋯ The PI seems to be correlated to the other spondylolisthesis risk factors: facet tropism and female sex. It carries the heaviest load in the progression towards sagittally oriented facet joints, which might lead to segmental instability and eventual spinal pathologies.

To assess radiological characteristics that may support the clinical diagnosis of trigeminal neuralgia caused by pure venous conflict. ⋯ Identification of shorter and/or thicker CN V on the affected side in patients with trigeminal neuralgia without an obvious offending vessel on magnetic resonance imaging may suggest the presence of pure venous conflict and help with decision making about microvascular decompression.

This study aims to elaborate on the application of virtual surgical planning (VSP) and 3-dimensional printing (3DP) guides in the surgical management of craniosynostosis and compare their surgical outcomes with traditional surgical planning. ⋯ With VSP and 3DP guides, precise preoperative planning, efficient intra-operative correction of cranial deformity, and objective surgical outcome assessment are achieved in craniosynostosis operations.

The application of the transorbital (TO) approach for vascular lesions has been scarcely explored. In this anatomic study, we examine the carotid and middle cerebral arteries from the TO perspective and investigate the feasibility of vascular clipping in a pseudovascularized model. ⋯ The TO approach provides anatomic access to the lateral and dorsal carotid siphon, complete posterior communicating artery, and proximal middle cerebral artery. This preliminary study suggests potential application in the elective treatment of paraclinoid and posterior communicating aneurysms.
