The subspecialized, clinically complex nature of neurosurgery should not result in marginalization or under-representation of neurosurgical scientific output. This study aims to provide an overview of the trends of neurosurgical publications in high-impact medical journals during the past 3 decades. ⋯ Neurosurgery's proportion of high-impact journal publications has increased over time.

Brain metastases (BMs) are the most frequent tumors of the central nervous system. Diffusion tensor imaging (DTI) is a magnetic resonance imaging technique that provides insights into brain microstructural alterations and tensor metrics and generates tractography to visualize white matter fiber tracts based on diffusion directionality. This systematic review assessed evidence from DTI biomarker alterations in BMs and comparable tumors such as glioblastoma. ⋯ DTI metrics provide noninvasive biomarkers for distinguishing BMs from other tumors and predicting outcomes. Key metrics included peritumoral FA and mean diffusivity.

Within neurosurgery, it has always been important to individualize patient care. In recent years, however, technological advances have brought a new dimension to personalized care as developing methods, including next-generation sequencing, have enabled us to molecularly profile pathologies with increasing scale and resolution. In this review, the authors discuss the history and advances in precision medicine and neurosurgery, focusing both on neuro-oncology, as well as its extension to other neurosurgical subspecialties. They highlight the important roles of neurosurgeons in past work and future work, with the extension of tissue collection and precision medicine principles to additional sample types and disease indications.

This study evaluates the impact of L4-L5 minimally invasive surgery (MIS)- transforaminal lumbar interbody fusion (TLIF) on adjacent-level parameters. ⋯ L4-L5 MIS-TLIF had a more consistent effect on L3-L4 than L5-S1. Although adjacent-level SL and DA decreased over time, their association with ASDeg appears limited, suggesting a multifactorial etiology. L4-L5 MIS-TLIF provides demonstrable clinical benefits with lasting PRO improvements and low adjacent-level reoperations.

Idiopathic intracranial hypertension (IIH) remains a poorly understood condition with no standardized treatment. Treatment is therefore generally individualized. Recent isolated reports have begun to describe the use of third ventriculostomy (open or closed) for the treatment of IIH. This review aims to communicate the current evidence for the use of third ventriculostomy in IIH. ⋯ Despite very plausible proposed mechanisms of action, there is currently a paucity of both studies and, therefore, evidence for the use of either endoscopic or open third ventriculostomy for the treatment of IIH. The studies done to date do strongly suggest that further consideration is warranted.
