Objective:
To describe the development, implementation, and validation of CranioFix, an augmented-reality (AR)-enhanced educational toolkit for the training of craniomaxillofacial trauma management, specifically orbit-zygomatic complex (OZC) fractures.
Background:
Surgical training in craniomaxillofacial trauma presents significant challenges due to the complexity of the anatomy, limited exposure to trauma cases, and the need for hands-on technical skill acquisition. Augmented-reality simulation technologies offer a promising solution to these limitations.
Methods:
CranioFix was developed as a hybrid AR and physical simulation model consisting of a 3D-printed skull with realistic tissue overlays, integrated surgical instruments, and a smartphone-based AR application. The app provides guided surgical instruction, anatomic overlays, and self-assessment tools. A validation study involving 15 surgeons and surgical trainees was conducted in a war-zone mission setting.
Results:
Participants reported significant improvement in confidence levels for OZC trauma management (mean precourse 3.2/10 versus postcourse 6.3/10). The educational content received high ratings for usefulness (9.1/10), interactivity (8.3/10), and overall design (8.2/10). All participants endorsed CranioFix as a valuable training tool and recommended its expansion to other craniofacial procedures.
Conclusion:
CranioFix is an effective, portable, and scalable AR-based simulation platform that enhances surgical training in craniomaxillofacial trauma. It is particularly valuable in resource-constrained or disrupted settings and has the potential for wide application in global surgical education.

01:14Cranial Bones: Superior and Posterior View
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,...
01:22Sutures of the Skull
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...
