Endoscopic transorbital approach for left anterior clinoidectomy, optic canal decompression and spheno-orbital meningioma resection
Bibliographic record
Abstract
Endoscopic transorbital approaches have been increasingly used to treat lesions of the middle fossa, such as sphenoid wing meningiomas or cavernous sinus disease, eschewing the cosmetic and functional consequences of a frontotemporal craniotomy, as well as technical shortcomings of endoscopic endonasal approaches. In this video, the authors present a case of a spheno-orbital meningioma for which an endoscopic transorbital approach was used for tumor resection, optic canal decompression, and anterior clinoidectomy. The advantages of this approach are demonstrated, particularly the direct, shorter distance to target along the axis of the middle fossa, which avoids neurovascular structures, brain retraction, and temporal muscle manipulation. The video can be found here: https://stream.cadmore.media/r10.3171/2025.1.FOCVID24199.

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.
