Evaluating the impact of a hand-crafted 3D-Printed head Model and virtual reality in skull base surgery training.

Introduction: While cadaveric dissections remain the cornerstone of education in skull base surgery, they are associated with high costs, difficulty acquiring specimens, and a lack of pathology in anatomical samples. This study evaluated the impact of a hand-crafted three-dimensional (3D)-printed head model and virtual reality (VR) in enhancing skull base surgery training.

Research Question: How effective are 3D-printed models and VR in enhancing training in skull base surgery?

Materials And Methods: A two-day skull base training course was conducted with 12 neurosurgical trainees and 11 faculty members.

Endoscopic endonasal extradural posterior clinoidectomy: A key maneuver to access the retrosellar and upper retroclival area.

Background: Endoscopic endonasal posterior clinoidectomy represents an important maneuver to improve access and visualization of the retrosellar and upper clivus area [1]. Three different techniques have been described in order to access and remove the posterior clinoid: 1) the intradural pituitary transposition [2], the interdural pituitary transposition [3] and a completely extradural technique [4].

Case Description: We present here a case of retrosellar and retroclival chordoma that has been removed through endoscopic endonasal approach.

Combined Petrosal Intertentorial Approach: A Cadaveric Study of Comparison With the Standard Combined Petrosectomy.

Background And Objectives: The combined petrosal intertentorial approach (CPIA) has been proposed as an alternative to standard combined petrosal approach (SCPA). CPIA has been designed to maintain integrity of the temporal dura with a view to reduce temporal lobe morbidity and venous complications. This study has been designed to perform a quantitative comparison between these approaches.

Endoscopic transcavernous approach for functional pituitary adenomas.

Background: Invasion of the CS is one of the limiting factors for total resection for PitNet tumors with cure rates less than 30%. Extended approaches may be considered in selective and well-studied cases of secreting adenomas.

Method: We describe the key steps of the endoscopic transcavernous approach for functional pituitary adenomas with a video illustration.

Cisternal nicardipine for prevention of delayed cerebral ischemia in aneurysmal subarachnoid hemorrhage: a comparative retrospective cohort study.

Purpose: Intrathecal vasoactive drugs have been proposed in patients with aneurysmal subarachnoid hemorrhage (aSAH) to manage cerebral vasospasm (CV). We analyzed the efficacy of intracisternal nicardipine compared to intraventricular administration to a control group (CG) to determine its impact on delayed cerebral ischemia (DCI) and functional outcomes. Secondary outcomes included the need for intra-arterial angioplasties and the safety profile.
