Summary
This study introduces a robot-guided technique for precise fibular osteotomy in mandibular reconstruction using fibula free flaps. The method proved accurate and user-friendly in preclinical models, offering a potential advancement in reconstructive surgery.
Area of Science:
- Oral and Maxillofacial Surgery
- Surgical Robotics
- Biomedical Engineering
Background:
- Current fibular osteotomy navigation for fibula free flap mandibular reconstruction can be complex, costly, and time-consuming.
- Patient-specific navigation and cutting guides necessitate significant expertise.
Purpose of the Study:
- To describe and evaluate a novel robot-guided osteotomy technique for mandible reconstruction.
- To assess the precision of robot-guided fibular osteotomy based on virtual preoperative planning.
Main Methods:
- A robot-guided osteotomy technique was developed for fibula free flap mandibular reconstruction.
- The technique was validated using five 3D-printed models and one cadaveric model.
- Precision was measured by comparing fragment lengths and angles to virtual planning data.
Main Results:
- The average deviation in crest lengths was 0.42 ± 0.29 mm (3D models) and 1.00 ± 0.53 mm (cadaver).
- Average angular deviation was 1.90 ± 1.22° (3D models) and 1.94 ± 0.69° (cadaver).
- The robot-guided technique demonstrated high precision in preclinical assessments.
Conclusions:
- Robot-guided fibular osteotomy positioning offers a precise and user-friendly approach for mandibular reconstruction.
- This technique shows potential for tailored fibula free flap reconstructions.
- Further clinical evaluation is warranted to confirm its efficacy in patient care.
