Bone Structure

Bone Structure

Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.

Bone Remodeling

Bone Remodeling

Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Area of Science:

Neurosurgery Simulation
Surgical Education Technology
Virtual Reality in Medicine

Background:

Virtual reality (VR) surgical rehearsal offers a safe educational environment requiring validation.
The middle cranial fossa (MCF) approach presents a challenging surgical simulation due to limited trainee exposure and high complication risks.

Purpose of the Study:

To validate a VR simulation of the MCF approach for educational purposes.
To assess face, content, and construct validities of the MCF VR simulation.
To evaluate performance changes through serial simulations.

Main Methods:

A high-fidelity MCF VR simulation was developed using CardinalSim software with cadaveric data.
Trainees from Neurosurgery and Otolaryngology performed MCF dissections on the VR platform.
Face and content validities were assessed using Likert scales; construct validity was evaluated by training level, and performance metrics were analyzed.

Main Results:

The VR simulation achieved face and content validities.
Trainee performance significantly improved post-simulation, with better dissection times, anterior petrosectomy completeness, and reduced critical structure injuries.
Construct validity was not demonstrated, as no trainees had prior MCF experience, underscoring the need for simulation.

Conclusions:

The MCF VR simulation using CardinalSim is validated for face and content.
The simulation effectively enhances understanding of complex MCF anatomy and neurovascular relationships.
This VR tool holds potential as a formative educational adjunct for Neurosurgery and Otolaryngology trainees.
