This study introduces an implant-oriented navigation system for orbital reconstruction, offering real-time feedback during surgery. This novel approach aims to improve implant positioning accuracy and surgical workflow efficiency.
Area of Science:
- Neurosurgery
- Medical Device Technology
- Surgical Navigation
Background:
- Current intraoperative navigation for orbital reconstruction requires surgeons to interpret 3D implant positions post-placement.
- Surgeons rely on delayed feedback, potentially impacting implant accuracy and surgical efficiency.
Purpose of the Study:
- To develop and evaluate an implant-oriented navigation approach providing real-time, intuitive feedback during orbital implant insertion.
- To assess the accuracy of this novel navigation method compared to traditional pointers.
Main Methods:
- A technical framework for implant-oriented navigation was established, including planning, implant tracking, and feedback mechanisms.
- A specialized navigation instrument and software tool were developed.
- An accuracy study compared the implant-oriented method against a standard navigation pointer.
Main Results:
- The implant-oriented navigation showed translation errors of 1.12-1.15mm (regular registration) and 0.81mm (accurate registration).
- Compared to the pointer (0.71-0.98mm and 0.54mm), the new method demonstrated competitive accuracy.
- Rotational errors were minimal, consistently below 3 degrees.
Conclusions:
- The developed implant-oriented navigation system provides real-time, intuitive feedback for orbital implant insertion.
- This approach holds potential for enhancing augmented reality and robotic-assisted surgical procedures.
- Further evaluation in clinical workflows is recommended to fully assess its impact.
