Endoscopic techniques for removal of intraorbital foreign bodies - a clinical series.
Article in Acta neurochirurgica, 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
backgroundManagement of intraorbital foreign bodies (IOFBs) is challenging due to the confined space and proximity of neurovascular and ocular structures. The increasing adoption of endoscopic techniques has expanded minimally invasive treatment options. We report operative corridors, indications, and outcomes of various endoscopic approaches in a consecutive series.
methodWe analyzed 16 patients with IOFBs treated between 2015 and 2023 at a tertiary university center. All procedures were performed using exclusively endoscopic techniques. Eleven IOFBs were metallic and five organic. Surgical strategy was individualized according to IOFB location and included endoscopic transethmoidal, transmaxillary, transconjunctival, and retrocantal approaches. Neuronavigation was used in all cases with adjunctive fluoroscopy or ultrasonography when indicated.
resultsNine IOFBs were intraconal and seven extraconal. Successful removal was achieved in 13 of 16 patients. All unsuccessful attempts involved small, non-ferromagnetic air-gun pellets located deep in the posterior orbit; these patients remain under observation without delayed inflammatory complications. No new postoperative visual deterioration or neurological deficits occurred. Transient periorbital edema was observed in all patients and resolved spontaneously. Cosmetic outcomes were satisfactory in all but one case with extensive initial soft-tissue loss. In three patients with presumed orbital tumors, removal of wooden fragments led to regression of inflammatory masses on follow-up.
conclusionsEndoscopic techniques represent a valuable alternative to traditional open approaches, especially for deep-seated lesions. The optimal approach should prioritize the most direct path to the target, avoiding critical structures such as the optic nerve, extraocular muscles, ciliary nerves and vessels to minimize the risk of permanent deficits.
