The endoscopic endonasal transcavernous (EET) approach is an increasingly popular approach for the cavernous sinus and surrounding structure lesions as well as a surgical corridor to pre-mesencephalic cisterns. This endoscopic study describes the main intracavernous branches of the internal carotid artery, providing nuances to improve the safety of this approach. ⋯ The MHT is a highly prevalent intracavernous branch, with 7 identifiable patterns based on DMA morphology and branch combination. This knowledge could guide surgeons in performing a safer EET approach.

The Council of State Neurosurgical Societies surveyed neurosurgeons applying for oral board certification in 2008 to assess their preparedness to practice. This survey was repeated in 2013 for a subsequent group of board applicants to evaluate the quality of neurosurgery training and identify opportunities for improvement. ⋯ The 2013 survey suggests that candidates for board certification in neurosurgery perceive themselves to be adequately prepared to independently perform nearly all neurosurgical procedures. However, additional work is required to optimize neurosurgery training in endovascular procedures and the socioeconomic aspects of neurosurgery practice.

Gliomas, particularly high-grade gliomas, are the most common primary brain tumors. From the Chinese Glioma Genome Atlas (CGGA) database, the relationships between the altered molecular pathways and gliomas could be easily observed. A close connection in the occurrence of the pathogenesis exists between the microenvironment, the glioma, and the associated genes. ⋯ Based on the study findings, we conclude that ZNF311 is potentially a novel biomarker for assessing prognosis and immune infiltration in glioblastoma and diffuse glioma cases.

Previous studies have shown that pedicle screw stimulation thresholds ≤6-8 mA yield a high diagnostic accuracy of detecting misplaced screws. Our objective was to determine the optimal "low" stimulation threshold to predict new postoperative neurologic deficits and identify additional risk factors associated with deficits. ⋯ Our results show that low thresholds are indicative of not only screw proximity to the nerve but also an increased likelihood of postoperative neurologic deficit. Thresholds ≤8 mA prove to be the optimal "low" threshold to help guide a correctly positioned pedicle screw placement and detect postoperative deficits.

To investigate the risk factors for increased surgical drain output after transforaminal lumbar interbody fusion (TLIF). ⋯ This study showed that older age, smoking, more fused levels, and intraoperative end plate injury were the independent risk factors, while administration of TXA was a protective factor for increased surgical drain output after TLIF.
