Exoscopic resection of tentorial meningiomas: Technical note from the exoscope era.
Article in Surgical neurology international, 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
Background: Tentorial meningioma resection is among the most challenging neurosurgical procedures. Various surgical approaches must be considered, including subtemporal, lateral suboccipital, occipital interhemispheric supratentorial, and supracerebellar transtentorial (SCTT) techniques. However, performing tentorial meningioma resections in the SCTT approach using operative microscopy often requires awkward positioning for the neurosurgeon. In this study, we report two cases of tentorial meningioma resection and discuss the utility and limitations of the 4KHD 3D operating room layout, showing the use of the exoscope (ORBEYE) system for this procedure. Methods: At our institution, we use the ORBEYE system (Olympus, Tokyo, Japan) for resecting tentorial meningioma. Peri-embolization and perioperative clinical and surgical data were retrospectively analyzed. Results: Our preferred exoscope system not only enhances visualization during neurosurgical procedures but also improves surgeon ergonomics during surgery. Conclusion: Exoscopic surgery using ORBEYE may help simplify complex neurosurgical procedures, including the resection of surgically challenging lesions such as tentorial meningiomas, although limitations remain in the management of large tumors.
