Real-time implant-oriented navigation significantly improves orbital reconstruction accuracy and reduces procedure time compared to traditional methods. This intuitive approach enhances surgeon feedback for better implant placement.
Area of Science:
- Neurosurgery
- Medical Imaging
- Surgical Navigation
Background:
- Intraoperative navigation aids orbital implant positioning but lacks real-time feedback.
- Surgeons must interpret delayed feedback for implant adjustments.
Purpose of the Study:
- To compare a real-time implant-oriented navigation approach with marker-based navigation in orbital reconstruction.
- To evaluate the impact on implant positioning accuracy, procedure duration, and surgeon experience.
Main Methods:
- A preclinical study involving 10 cadavers (20 orbital defects) reconstructed twice by two surgeons (80 total reconstructions).
- Comparison between real-time implant-oriented navigation and marker-based navigation.
Main Results:
- Real-time navigation significantly improved implant positioning accuracy in roll (2.0° vs. 3.2°), yaw (2.2° vs. 3.4°), and translation (1.3mm vs. 1.8mm).
- Procedure duration was reduced (median 4.5 min vs. 7.5 min) with real-time navigation.
- Surgeon subjective appreciation was higher for the real-time approach (mean 9.0 vs. 7.5).
Conclusions:
- Real-time implant-oriented navigation offers intuitive, immediate feedback for orbital reconstruction.
- This approach leads to superior implant positioning, shorter procedure times, and enhanced surgeon satisfaction.
