Optimized 3D digital surgical guides combined with titanium plates significantly improved outcomes for complex midfacial fractures. This innovative approach enhances facial symmetry and surgical accuracy, offering better patient results.
Area of Science:
- Oral and Maxillofacial Surgery
- Medical Imaging
- Biomedical Engineering
Background:
- Complex midfacial fractures present significant treatment challenges.
- Traditional methods often yield suboptimal aesthetic and functional results.
Purpose of the Study:
- To evaluate the efficacy of optimized three-dimensional (3D) digital surgical guide plates combined with preformed titanium plates for treating complex midfacial fractures.
Main Methods:
- A randomized controlled trial involving 26 patients with complex midfacial fractures.
- Three groups were compared: Group A (3D guides + titanium plates), Group B (titanium plates only), and Group C (conventional treatment).
- Outcomes assessed included clinical effects, patient-reported outcomes, midfacial contour, facial symmetry, and surgical accuracy.
Main Results:
- Group A demonstrated superior postoperative clinical effects and patient-reported outcomes compared to Groups B and C.
- Significant improvements in midfacial contour, facial symmetry, and surgical accuracy were observed in Group A.
- Analysis of orbital volume difference and maximum deviation indicated an ideal surgical treatment effect in Group A.
Conclusions:
- Optimized 3D digital surgical guide plates accurately guide the placement of preformed titanium plates.
- This combined approach significantly enhances treatment outcomes for complex midfacial fractures.
