Endoscopic endonasal surgery for optic nerve sheath and optic canal meningiomas: 2D operative video.
Article in Neurosurgical focus: Video, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Meningiomas invading the ventromedial optic canal are uncommon anterior cranial fossa tumors that present with progressive visual decline. Their close relationship with the optic nerve and ophthalmic artery makes surgical intervention highly complex. This video presents two illustrative cases-an optic nerve sheath meningioma and an optic canal meningioma-both treated using an endoscopic endonasal approach (EEA). This direct ventral corridor provides early optic canal decompression and panoramic visualization of critical neurovascular structures, avoiding optic nerve manipulation. The same technique was employed in both cases, but was tailored to the distinct surgical challenges of optic nerve sheath and optic canal meningiomas.
