Cortico-amygdalohippocampectomy (CAH) is effective for mesial temporal lobe epilepsy (mTLE). Concerns regarding surgical morbidity have generated enthusiasm for more minimally invasive interventions. A careful analysis of current data is warranted before widespread adoption of these techniques. ⋯ Based on nonrandomized data, LITT has compelling evidence of efficacy; however, comparisons to surgical resection are lacking. SRS has a latency period and is inferior to CAH (ROSE trial). RF-TC is a less resource-intensive alternative to LITT; however, comparisons of efficacy are limited. Additional studies are needed before minimally invasive procedures can supplant standard surgery.

Currently, different postoperative predictors of chordoma recurrence have been identified. Tumor growth rate (TGR) is an image-based calculation that provides quantitative information of tumor's volume changing over time and has been shown to predict progression-free survival (PFS) in other tumor types. ⋯ TGR may be considered as a preoperative radiological indicator of tumor proliferation and seems to preoperatively identify more aggressive tumors with a higher tendency to recur. Our findings suggest that the therapeutic strategy and clinical-radiological follow-up of patients with chordoma can be adapted also according to this new parameter.

In adults with ischemic moyamoya disease (MMD), the efficacy of direct vs indirect revascularization procedures remains a matter of debate. ⋯ There was no difference in early postoperative events, long-term infarction or hemorrhage, or clinical outcome between direct and indirect revascularization. However, there was a significant decrease in all ischemic and hemorrhagic events combined in direct revascularizations compared to indirect revascularizations.

Fluorescence-guided surgery (FGS) is under investigation as a means to improve the extent of resection for primary central nervous system (CNS) tumors. Tozuleristide, known also as "Tumor Paint," is an investigational tumor-targeting agent covalently conjugated to a derivative of the fluorescent dye indocyanine green. ⋯ This finding deserves further investigation to determine if tozuleristide "Tumor Paint" may have a wider role in the identification of non-neoplastic intracranial pathologies.

Safety checklists have improved surgical outcomes; however, much of the literature comes from general surgery. ⋯ Multidisciplinary time-outs have become standard of care in neurosurgery. Despite proximity and overlapping personnel, there is considerable variability between hospitals in the practice of time-outs. This lack of uniformity, allowed for by flexible World Health Organization guidelines, may reflect the origins of surgical time-outs in general surgery, rather than neurosurgery, underscoring the potential for time-out optimization with neurosurgery-specific considerations.
