Abstract
BACKGROUND: Ethmoidal dural arteriovenous fistulas (eDAVFs) are usually approached via a pterional or a frontal craniotomy. A more direct route to the fistula is possible through a purely transfrontal sinus approach. The aim of this report is to illustrate the interest of transsinus frontal approach for eDAVFs. CASE DESCRIPTION: The transfrontal sinus approach is described and illustrated in a case of an ethmoidal arteriovenous fistula. This approach is the most direct when treating an eDAVF surgically, allowing preserving neural structures with minimal to no brain manipulation. CONCLUSION: For eDAVFs, the purely transfrontal sinus approach is highly worth considering in cases of large frontal sinuses.

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 it
