Central neurocytomas (CNs) usually occur in young adults, and the clinical characteristics and surgical outcomes of patients in different age groups may be different. ⋯ CNs in younger adult patients behave differently from those in the older age group. Surgery can halt neurologic deterioration and ensure satisfactory outcomes.

Superficial temporal artery (STA)-middle cerebral artery (MCA) bypass surgery has been widely adopted in treating moyamoya disease (MMD). Geometric variations including high tortuosity and stenosis exist in many cases, but the hemodynamic effects have not been comprehensively evaluated. We aim to evaluate the hemodynamic effects of bypass geometry variations based on patient-specific data. ⋯ High tortuosity and stenosis can significantly change the hemodynamics of STA-MCA bypass, and the optimization of bypass geometry deserves further consideration.

Microvascular decompression (MVD) is an effective nondestructive neurosurgical procedure for trigeminal neuralgia (TN). However, some patients may undergo surgery failure or experience pain recurrence, sparking debates on the need for reoperation. ⋯ The redo MVD for TN is equally efficacious and safe compared to the primary procedure, with an emphasis on meticulous dissection and thorough decompression. Additionally, nerve combing proves to be an effective supplementary option for patients without obvious compression.

Comparative Study
Comparison of early postoperative diffusion-weighted magnetic resonance imaging findings after resection of gliomas and meningiomas.
Glioma and meningioma require vastly different surgical approaches, even if only involving a simple craniotomy procedure. Diffusion weighted imaging (DWI) is useful for the postoperative evaluation of ischemic damage. The present study evaluated the expected but unproven differences in DWI findings. ⋯ Postoperative early DWI-positive rate and rim-type lesions are more common after glioma resection than meningioma resection. Larger volumes of DWI-positive areas may be associated with postoperative neurological symptoms in gliomas. DWI-positive finding is less common after meningioma than glioma resection but more likely to be associated with new neurological symptoms. These differences are important for adequate postoperative DWI evaluation of common supratentorial brain tumors.

This prospective study assesses the acceptance and usefulness of augmented 360° virtual reality (VR) videos for early student education and preparation in the field of neurosurgery. ⋯ This study demonstrated the high acceptance of augmented 360° VR videos as a valuable tool for early student education in neurosurgery. While hands-on training remains indispensable, these videos promote conceptual knowledge, ignite interest in neurosurgery, and provide a much-needed orientation within the operating room. The incorporation of detailed explanations throughout the surgeries with augmentation using superimposed elements, offers distinct advantages over simply observing live surgeries.
