Temporal Vascularized Fascial Flap Combined With Bilayer Artificial Dermis for Scalp Reconstruction With Calvarial Exposure: A Bioengineering Strategy Integrating Angiogenesis and Dermal Regeneration
Bibliographic record
Abstract
The reconstruction of traumatic scalp defects with skull exposure presents multifaceted challenges, including compromised vascular reconstruction, periosteal defects, and high aesthetic demands. This study reports the case of a 57-year-old female patient with a post-traumatic right temporal scalp defect and skull exposure after a traffic accident. A staged protocol involving negative pressure wound therapy, pedicled fascial flap transfer, and bilayer artificial dermis grafting achieved complete wound closure within 15 days. At the 8-month follow-up, the Vancouver Scar Scale score was 1, demonstrating optimal aesthetic and functional restoration. This approach synergizes the vascularization advantages of fascial flaps with the regenerative properties of artificial dermis, effectively addressing limitations of traditional methods-such as flap bulkiness and donor site morbidity-and offers a novel paradigm for skull exposure defect reconstruction.

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.
