Fronto-orbital advancement with patient-specific 3D-printed implants and robot-guided laser osteotomy: an in vitro accuracy assessment.

Purpose: The use of computer-assisted virtual surgical planning (VSP) for craniosynostosis surgery is gaining increasing implementation in the clinics. However, accurately transferring the preoperative planning data to the operating room remains challenging. We introduced and investigated a fully digital workflow to perform fronto-orbital advancement (FOA) surgery using 3D-printed patient-specific implants (PSIs) and cold-ablation robot-guided laser osteotomy.

Early minimally invasive image-guided eNdoscopic evacuation of iNTracerebral hemorrhage: a phase II pilot trial.

Background: Whether minimally invasive endoscopic surgery (ES) improves survival and functional outcome in people with spontaneous supratentorial intracerebral hemorrhage (SSICH) is unknown.

Methods: This is a single-center pilot study performed between July 2021 to January 2023. Any supratentorial hematoma with a volume between 20 mL and 100 mL was endoscopically evacuated within 24 h after bleeding onset.

Innovating neurosurgical training: a comprehensive evaluation of a 3D-printed intraventricular neuroendoscopy simulator and systematic review of the literature.

Objective: The objective of this study was to develop and evaluate a low-cost 3D-printed simulator to improve the ability of neurosurgical residents to handle and coordinate endoscopes in performing technically demanding procedures such as neuroendoscopic removal of ventricular tumors or endoscopic third ventriculostomy (ETV).

Methods: The simulator was developed, printed in-house, and evaluated in a trial involving neurosurgery residents who performed ETV and intraventricular tumor resection tasks using it. Participants completed a questionnaire that assessed various aspects of the simulator's effectiveness, including anatomical visualization, procedural understanding, competency enhancement, and subjective impressions.

Virtual reality for patient informed consent in skull base tumors and intracranial vascular pathologies: A pilot study.

Purpose: With the growing demand for shared decision-making and patient-centered care, optimal informed consent (IC) has gained relevance. Virtual reality (VR) has seen significant technological advancements, and its medical applications currently include surgical planning and medical education. This pilot study investigates the feasibility of VR-enhanced informed consent (VR-IC) in neurosurgery to improve preoperative IC and patient satisfaction.

Assessment of Interrater Reliability and Accuracy of Cerebral Aneurysm Morphometry Using 3D Virtual Reality, 2D Digital Subtraction Angiography, and 3D Reconstruction: A Randomized Comparative Study.

Background/objectives: Detailed morphometric analysis of an aneurysm and the related vascular bifurcation are critical factors when determining rupture risk and planning treatment for unruptured intracranial aneurysms (UIAs). The standard visualization of digital subtraction angiography (DSA) and its 3D reconstruction on a 2D monitor provide precise measurements but are subject to variability based on the rater. Visualization using virtual (VR) and augmented reality platforms can overcome those limitations.
