Summary
Surgical navigation precisely transfers preoperative plans to fibula flap mandible reconstruction. This technique enhances accuracy, aiding surgeons in achieving superior cosmetic and functional results for patients.
Area of Science:
- Oral and Maxillofacial Surgery
- Biomedical Engineering
- Reconstructive Surgery
Background:
- The mandible is crucial for facial aesthetics and function.
- Mandibular reconstruction often utilizes fibula free flaps.
- Precise reconstruction is essential for optimal outcomes.
Purpose of the Study:
- To describe and evaluate surgical navigation-assisted mandibular reconstruction using fibula flaps.
- To assess the accuracy of transferring preoperative designs to the surgical site.
- To determine the repeatability of the technique in achieving planned outcomes.
Main Methods:
- Utilized custom dental splints to immobilize the mandible.
- Performed computed tomography (CT) scans, preoperative design, and surgery with the mandible in a fixed position.
- Evaluated postoperative results using CT scans at one week to assess repeatability.
Main Results:
- Twenty patients were included in the study.
- High repeatability was observed between the preoperative design and postoperative results.
- Repeatability was 79.1% within 1mm, 87.1% within 2mm, and 91.9% within 3mm.
Conclusions:
- Surgical navigation enables precise transfer of preoperative designs in fibula flap mandibular reconstruction.
- The technique assists surgeons in achieving excellent cosmetic and functional results.
- This method improves the predictability and accuracy of mandibular reconstruction.
