Summary
Virtual surgical planning (VSP) for complex mandibular fractures significantly improves surgical accuracy and reduces operating time compared to traditional methods. This approach leads to better anatomical reduction and fewer complications.
Area of Science:
- Oral and Maxillofacial Surgery
- Biomedical Engineering
- Medical Imaging
Background:
- Complex mandibular fractures present significant surgical challenges.
- Traditional surgical techniques often result in suboptimal outcomes.
- Virtual surgical planning (VSP) offers a promising alternative for managing these fractures.
Purpose of the Study:
- To quantitatively assess the effectiveness of VSP compared to traditional surgery for complex mandibular fractures.
- To evaluate the accuracy and efficiency of VSP in jaw reconstruction.
Main Methods:
- 30 patients with complex mandibular fractures were divided into two groups: VSP (Group A) and traditional surgery (Group B).
- In Group A, pre-modeled plates were used based on virtual planning.
- In Group B, plates were shaped intraoperatively.
- Discrepancies were measured in millimeters using post-operative CT scans.
Main Results:
- Group A (VSP) showed mean discrepancies <1 mm, indicating high accuracy.
- Group B (traditional surgery) had mean discrepancies between 1.36 and 1.94 mm.
- Mean operative time was significantly reduced in Group A (69 min) compared to Group B (106 min).
Conclusions:
- Virtual surgical planning and pre-modeled plates ensure more anatomically accurate fracture reduction.
- VSP significantly decreases operative times.
- These improvements lead to a reduction in both short-term and long-term surgical complications.
