Lateral oromandibular defect: When is it appropriate to use a bridging reconstruction plate combined with a soft tissue revascularized flap?
Bibliographic record
Abstract
BACKGROUND: A quasi-experimental retrospective study was undertaken to evaluate a new concept of free tissue volume restoration combined with bridging reconstruction plate (compartment approach) to reduce plate-related complication rates. METHODS: We evaluated 40 patients with large lateral mandible defects and associated complex soft tissue defects reconstructed with a revascularized soft tissue flap and titanium hollow screw reconstruction plates. A case-control comparison was performed based on reconstruction type: restoration of soft tissue defect (conventional approach-group 1) versus over-reconstruction of soft tissue defect (compartment approach-group 2). RESULTS: Plate exposure rate was 6 of 16 (38%) in group 1 versus 2 of 24 (8%) in group 2, and the difference was statistically significant (p = .04). The mean time to exposure was 10 months. Plate fracture rate was 6 of 23 (26.1%) in dentulous patients versus 1 of 17 (5.9%) in edentulous patients. Gastrostomy tube dependence was 6 of 16 (38%) in group 1 versus 6 of 24 (25%) in group 2. CONCLUSION: The "compartment approach" reduces plate exposure rate and gastrostomy tube dependence. Revascularized osseocutaneous reconstruction is still required in dentulous patients.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
