Summary
This study presents an improved technique for reconstructing complex maxillary defects using a deep circumflex iliac artery (DCIA) flap, guided by virtual surgical planning and intraoperative navigation for enhanced accuracy.
Area of Science:
- Oral and Maxillofacial Surgery
- Plastic and Reconstructive Surgery
- Biomedical Engineering
Background:
- Maxillary reconstruction for Brown's Class III defects presents significant geometric challenges.
- Traditional methods may lack the precision required for optimal functional and aesthetic outcomes.
Observation:
- A novel approach utilizing a composite deep circumflex iliac artery (DCIA) flap was employed.
- Virtual surgical planning incorporated patient-specific cutting templates, surgical guides, and rapid prototype models.
- Intraoperative navigation systems guided the surgical procedure precisely.
Findings:
- The virtual surgical planning and navigation system facilitated accurate reconstruction of the maxillary defect.
- The root mean square error of the reconstructed area was 3.68 mm.
- Mean errors for DCIA segments were minimal, measuring 0.61 mm (lateral) and 0.85 mm (medial).
Implications:
- This integrated approach offers a potential advancement in achieving superior outcomes for complex maxillary reconstructions.
- The use of patient-specific guides and navigation may improve surgical precision and reduce complications.
- This methodology could be a valuable tool for treating extensive maxillary defects in reconstructive surgery.
