Abstract

fetched live from OpenAlex

To assess the validity of the current approach to craniofacial repairs whereby the contralateral hemiface is used as a template for surgical repair, this study aims to provide a comprehensive analysis of facial skeletal symmetry in normal human faces beginning with the zygomatic bone. Three‐dimensional models generated in OsiriX from the CT scans of 30 adult male patients displaying normal skeletal anatomy were used to assess the symmetry at seven bilateral zygomatic landmarks. All landmarks displayed a deviation from perfect symmetry, ranging from 1.41 to 3.13 mm, and statistically significant differences were observed in the asymmetry scores across the seven zygomatic landmarks (F(6,203)=5.951, p<0.005). The zygion demonstrated significantly greater asymmetry than other more medially‐located landmarks including the orbitale, jugale, and frontozygomatic suture. These results suggest that bony asymmetry can be measured and there is a significant degree of asymmetry in the zygomatic bone, particularly in the temporal process and extending into the zygomatic arch. Such deviations may warrant a re‐evaluation of current surgical approaches to the repair of zygomatic bone fractures.

Not 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.
