Traumatic Arch Injury: Indications and an Endoscopic Method of Repair
Bibliographic record
Abstract
The unique strategic position of the zygomatic arch makes it an important surgical landmark in facial fracture repair. Because of the numerous negative sequelae associated with the traditional coronal approach to the arch, it has frequently been omitted as a point of reduction and fixation. Endoscope-assisted repair allows accurate zygomatic arch restoration without the setbacks of coronal access. The indications for arch repair include markedly displaced isolated arch fractures, complex zygoma fractures with arch comminution, and Le Fort III level fractures. In complex zygoma fractures, the arch helps accurately restore midface projection and width and serves as an additional stable anchor point. In Le Fort III fractures, restoration and fixation of the arch are essential components of the repair necessary to stabilize the maxillary dentition to the cranial base. Endoscopic arch repair is a novel, technically challenging procedure that requires a different set of surgical skills and considerable training. Implementation of appropriate teaching programs and further advances in instrument development will overcome the steep learning curve associated with this technique and encourage its use.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
