Single-stage surgical treatment of cranial intraosseous meningiomas includes complete tumor resection followed by aesthetic reconstruction. Tailored tumor resection with a computer-aided design/computer-aided manufacturing custom-made implant for the defect has been advocated in recent years to achieve a satisfactory cosmetic result with reduced operative time and fewer complications. However, several technical nuances related to the area of osseous removal may compromise cranioplasty. ⋯ Custom templates based in cranial sutures may benefit single-step frame-guided resection and reconstruction of intraosseous tumors with compelling results.

Cone-beam computed tomography (CBCT) images for skull base tumors provide detailed vascular information and localization in regard to surrounding bony structures. We report use of the CBCT fusion technique for skull base meningiomas. ⋯ CBCT fusion images clearly visualized the feeders from each arterial system, the vascular compartments within the tumor, and possible peritumoral anastomoses. This technique provides a substantial contribution to both preoperative embolization and surgical resection of skull base meningiomas.

The impact of the coronavirus disease 2019 (COVID-19) pandemic has led to a significant transformation in medical practice and training. This nationwide survey study aims to evaluate the 1-year impact of the pandemic on training of neurosurgical residents. ⋯ COVID-19 has had a significant impact on neurosurgical practice and training. Effective measures should be used to mitigate these effects and better prepare for the future challenges.

Skull base osteosarcoma is a rare and aggressive tumor that is most commonly treated with primary surgical resection and adjuvant chemoradiation. Using the National Cancer Database, we analyzed demographic and clinical prognosticators for overall survival (OS). ⋯ Tumor histologic subtype, advanced tumor grade, and greater tumor size are predictors of worse OS in skull base osteosarcoma. No significant differences in OS were identified based on treatment modality, which warrants further investigation.

Intrasaccular flow-disruption with the Woven EndoBridge for narrow-necked aneurysms: A safety and feasibility study.
The Woven EndoBridge (WEB) received U.S. Food and Drug Administration approval for endovascular treatment of wide-necked bifurcation aneurysms. We evaluated the feasibility, safety, and efficacy of the WEB for treatment of narrow-necked aneurysms. ⋯ WEB embolization of narrow-necked aneurysms was technically feasible and safe and might be considered as an alternative treatment option to conventional coiling in selected cases.
