To compare the results of full-endoscopic decompression (FED) in lumbar lateral recess stenosis via an interlaminar or transforaminal approach. ⋯ FED could provide satisfactory clinical outcomes for lumbar lateral recess stenosis. However, the IL-FED procedure demonstrated shorter operation time and lesser radiation exposure, but higher risk for anesthetic when compared with the TF-FED procedure.

We report a retrospective analysis of hardware failure in patients requiring instrumentation for spinal metastasis. ⋯ The rate of hardware failure in this cohort was 13.8%, although operative revision rate was 3.4%. Spinal instrumentation in patients with poor preoperative functional status or multiple myeloma may be more likely to develop instrumentation failure.

Glioblastoma (GBM) is associated with increased risk of developing dural venous sinus thrombosis (DVST), which often goes undiagnosed as symptoms are readily attributed to tumor. The purpose of this study was to investigate the incidence of DVST, potential predictive features on imaging, complications, its effect on survival, and time of greatest risk for developing DVST. ⋯ Patients with GBM have increased risk of developing DVST, independent of surgical treatment or chemoradiation. DVST presence does not affect survival. Tumor invasion of dural sinuses and greater T1/fluid-attenuated inversion recovery ratio on preoperative imaging were the most significant predictors of DVST development.

The role of maxillofacial trauma in dementia risk is not well established. The aim of this study was to evaluate the association between craniofacial trauma, including facial bone fracture and traumatic brain injury (TBI), and dementia. ⋯ Craniofacial traumas, especially facial bone fracture, were associated with an increased risk of subsequent dementia. Maintaining a high index of suspicion for associated TBIs in all patients with facial trauma is crucial, even if no obvious initial signs and symptoms of brain injury are observed.

Standard electrostimulation cortical mapping includes application of electrical current to the explored areas through an electrode and marking of functional zones by means of paper tags with different symbols. This approach has several disadvantages. First, the electrode is moved randomly. It leads to overlooking of some zones, which causes mapping deficiency, and restimulation of others, which can trigger epileptic seizures. Second, the tags easily shift and close the marked structures. We describe a new simple device that provides precise cortical mapping without indicated problems and the technique to apply it. ⋯ Our case illustrates that the proposed invention can be successfully used in neurosurgical operations for precise electrostimulation mapping of the brain cortex.
