Summary
Virtual surgical planning (VSP) and splint-guided surgery improve accuracy and efficiency in complex second-stage mandibular reconstruction. This technique offers a reliable solution for anatomical restoration after tumor resection.
Area of Science:
- Oral and Maxillofacial Surgery
- Biomedical Engineering
- Reconstructive Surgery
Background:
- Second-stage mandibular reconstruction presents challenges due to anatomical distortion and bone displacement following tumor resection.
- Virtual surgical planning (VSP) is an emerging technique to enhance precision and efficiency in complex reconstructive procedures.
Purpose of the Study:
- To evaluate the efficacy of VSP combined with splint-guided surgery for second-stage mandibular reconstruction using vascularized iliac crest bone flaps.
Main Methods:
- Five patients with mandibular defects underwent VSP-aided secondary reconstruction using serial guiding splints.
- Surgical outcomes were assessed by analyzing linear and 3D deviations from presurgical designs.
- Patient complications and feedback were monitored during follow-up.
Main Results:
- All five reconstructions were successful using vascularized iliac crest bone flaps.
- Postoperative deviations were minimal: coronal plane (2.7 ± 0.4 mm, 0.70 ± 0.6 mm), sagittal plane (2.4 ± 0.88 mm), and overall 3D deviation (1.2 ± 1.7 mm).
- No significant donor or recipient site complications were reported during follow-up.
Conclusions:
- Splint-guided surgery, when well-designed, facilitates accurate and efficient second-stage mandibular reconstruction.
- This technique is a reliable option for complex mandibular defects, though design adaptation is crucial for varied cases.
