Summary
Secondary revision of maxilla reconstructions is challenging. A novel approach using virtual surgical planning and intraoperative navigation improved facial symmetry and functionality in four cases.
Area of Science:
- Oral and Maxillofacial Surgery
- Plastic and Reconstructive Surgery
- Medical Engineering
Background:
- Secondary revision of maxilla reconstructions presents challenges due to altered anatomy.
- Scapula tip flaps are used for maxillary reconstruction.
- Achieving symmetry and functionality in revisions is difficult.
Observation:
- Four cases of maxillectomy reconstruction using scapula tip flaps were reviewed.
- A combined approach of virtual surgical planning (VSP) and intraoperative navigation (ION) was employed.
- VSP involved superimposing mirrored normal anatomy onto the reconstructed area.
Findings:
- Intraoperative navigation provided real-time anatomical mapping during surgery.
- The VSP and ION approach facilitated precise bony revisions and recontouring.
- All four cases demonstrated improved anatomical symmetry and functional outcomes.
Implications:
- This combined VSP and ION technique offers a viable solution for complex maxillary revisions.
- It enhances the ability to restore facial symmetry and function after maxillectomy.
- The methodology holds potential for improving reconstructive surgery outcomes in challenging cases.
