This study introduces an augmented reality (AR) navigation system to improve endoscopic skull base surgery (ESBS). The AR system enhances surgeon precision and safety by providing an extended viewport and reducing errors during simulated surgical tasks.
Area of Science:
- Neurosurgery
- Medical Imaging
- Augmented Reality
Background:
- Endoscopic skull base surgery (ESBS) offers an alternative surgical approach.
- Limited endoscope field of view can cause surgeon fatigue and discomfort.
Purpose of the Study:
- To develop and evaluate an augmented reality (AR) navigation system for ESBS.
- To enhance the surgeon's view and improve surgical precision and safety.
Main Methods:
- Developed an AR navigation system overlaying 3D anatomical models onto endoscopic images.
- Utilized state-of-the-art endoscopic calibration and optical tracking for accuracy.
- Assessed system accuracy with mean spatial errors of approximately 1 mm.
Main Results:
- The AR system demonstrated accuracy within the acceptable range for ESBS.
- Simulated surgical tasks showed decreased error events (number and duration) using the AR system.
- Human subjects performed tasks more precisely and safely with the AR system compared to conventional endoscopy.
Conclusions:
- The developed AR-based navigation system enhances precision and safety in ESBS.
- AR technology offers a significant improvement over conventional endoscopic visualization for complex skull base procedures.

Cranial Bones: Lateral View
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...

Cranial 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,...
