Summary
This study introduces a virtual reality (VR) application integrating stereoscopic surgical videos with interactive 3D anatomical models. This novel tool enhances surgical training for complex procedures by allowing trainees to explore patient-specific anatomy.
Area of Science:
- Medical Simulation
- Virtual Reality in Surgery
- Anatomical Modeling
Background:
- Current virtual reality (VR) technology enables 3D stereoscopic instructional videos.
- Integrating 3D anatomical models with VR can simulate surgical procedures for learning and preoperative planning.
Purpose of the Study:
- To propose and develop a standalone VR application for surgical training.
- The application allows interaction with modular 3D anatomical models synchronized with stereoscopic surgical videos.
Main Methods:
- Stereoscopic video was captured using an OPMI Pentero 900 microscope.
- 3D anatomical models were created by segmenting axial temporal bone computed tomography (DICOM) images.
- Models were imported into the Unreal Engine and viewed using an Oculus Go VR headset.
Main Results:
- The VR environment enabled simultaneous viewing of stereoscopic video and manipulation of interactive 3D models.
- Users could control model transparency, segmentation highlighting, and anatomical labels.
- The system allows for 1.1 × 10^12 combinations of patient-specific anatomical structures per DICOM series.
Conclusions:
- This research demonstrates the feasibility of combining stereoscopic video with VR simulation.
- The developed tool shows potential to significantly assist lateral skull base trainees in navigating complex 3D surgical environments.

01:27Cranial Bones: Lateral View
3.3K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:22Sutures of the Skull
8.6K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

01:08Overview of the Skull
6.2K
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

01:14Cranial Bones: Superior and Posterior View
3.7K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
