A Cadaveric Study Evaluating the Feasibility of the Amplatzer Septal Occluder for Skull Base Reconstruction in Endoscopic Endonasal Surgery: Can Occluders Offer a Viable Alternative for Skull Base Repair?

Background And Objectives: Effective reconstruction of skull base defects after endonasal endoscopic surgery is essential to prevent complications such as cerebrospinal fluid leakage and infection. Traditional methods may not always provide optimal outcomes for certain defects. This study evaluates the feasibility of using the Amplatzer Septal Occluder (ASO) as an adjunctive tool for skull base reconstruction in a cadaveric model.

Ultra-Low-Cost Homemade Reusable Tumor Resection Model With Realistic Haptic Feedback and Photograph-Based Navigation for Neurosurgical Training.

Background And Objectives: Neurosurgical education requires meticulous training tools that offer realistic haptic feedback and are, ideally, cost-effective. The current training models, including cadaveric specimens and high-fidelity simulators, are often expensive, inaccessible, and single-use, limiting their adoption in resource-constrained settings. To address this gap, we developed a novel, ultra-low-cost, reusable brain tumor resection model with realistic haptic feedback and photograph-based navigation.

Hippocampal Radiation Exposure and Cognitive Outcomes After Single-Fraction Gamma Knife Radiosurgery for Benign Sellar and Parasellar Lesions: A Prospective Study.

Introduction: This study evaluates hippocampal dosimetry and neurocognitive outcomes in patients undergoing Gamma Knife radiosurgery (GKRS) for benign sellar, parasellar, and suprasellar lesions. While hippocampal protection has been well studied in whole-brain radiotherapy (WBRT), its relevance in stereotactic radiosurgery (SRS) remains underexplored. This study systematically investigates hippocampal radiation dose thresholds and associated neurocognitive outcomes in patients undergoing single-fraction Gamma Knife radiosurgery specifically for benign sellar and parasellar lesions.
