Summary
This study introduces a resin template to improve computer-assisted maxillofacial surgery, enhancing the translation of virtual plans to surgical outcomes. The method also provides a reliable way to assess the accuracy of virtual surgical planning.
Area of Science:
- Maxillofacial surgery
- Biomedical engineering
- Surgical planning
Background:
- Computer-assisted surgery is advancing, but challenges remain in translating virtual plans to clinical practice and assessing planning repeatability.
- Accurate execution of virtual surgical plans at the bedside is crucial for successful maxillofacial reconstruction.
Observation:
- A resin template, created using rapid prototyping based on virtual surgical designs, was used to guide fibula flap shaping in seven patients undergoing maxillofacial reconstruction.
- The template acted as a physical intermediary, bridging virtual planning and surgical execution.
Findings:
- The resin template technique demonstrated satisfactory clinical outcomes in all patients.
- Repeatability analysis showed high accuracy, with mean matching percentages of 87.5% within 1 mm for isolated bone grafts and 71.4% within 1 mm for reconstructed mandibles or maxillae.
- A quantitative three-dimensional differential analysis method was established for evaluating virtual plan repeatability.
Implications:
- Resin templates are a reliable tool for translating virtual maxillofacial surgical plans into tangible surgical actions.
- The developed method offers an objective and quantitative approach to assess the repeatability of virtual surgical planning in maxillofacial reconstruction.
