Summary
Computer-assisted navigation enhances mandibular reconstruction surgery. This technology provides real-time 3D guidance, improving accuracy and patient satisfaction in fibula free flap procedures.
Area of Science:
- Oral and Maxillofacial Surgery
- Biomedical Engineering
- Surgical Navigation Systems
Background:
- Mandibular reconstruction is complex, often requiring precise anatomical restoration.
- Fibula free flap surgery is a common method for reconstructing the mandible.
- Achieving optimal functional and aesthetic outcomes necessitates accurate surgical placement.
Purpose of the Study:
- To evaluate the effectiveness of computer-assisted navigation in mandibular reconstruction.
- To assess the accuracy and outcomes of navigation-guided fibula free flap procedures.
- To determine the utility of intraoperative navigation for improving surgical precision.
Main Methods:
- Retrospective review of eight patients undergoing navigation-guided mandibular reconstruction.
- Utilized intraoperative navigation to confirm ideal positions of mandibular angles and condyles.
- Postoperative evaluation included panoramic radiographs, CT scans, and image fusion for assessment.
Main Results:
- Successful completion of navigation-guided mandibular reconstructions based on preoperative planning.
- Mean surgical discrepancy at the mandibular angle was 1.92 ± 0.97 mm.
- All patients reported satisfaction with functional and aesthetic results, with condyles accurately seated.
Conclusions:
- Computer-assisted navigation is a viable technology for enhancing mandibular reconstruction.
- Real-time 3D surgical references provided by navigation improve operative outcomes.
- This technology assists surgeons in achieving precise and satisfactory results.
