A preliminary report of a modified endoscopic vidian neurectomy approach and its anatomic landmarks.
Article in BMC surgery, 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
backgroundEndoscopic vidian neurectomy has been performed for decades on patients with refractory allergic rhinitis and vasomotor rhinitis. Although the surgical approach has evolved continuously, it still has deficiencies in terms of accuracy and safety. To overcome these deficiencies, we conducted anatomical study to propose a modified endoscopic vidian neurectomy.
methodsFive adult dry skulls and seven fresh skull specimens were used to identify landmarks for locating the vidian nerve. The modified surgical approach was applied to 9 patients with allergic or vasomotor rhinitis to test its feasibility and safety.
resultsWe confirmed and successfully applied the sphenoidal process of the palatine bone, the medial pterygoid plate, and the bony crest extending from the root of the pterygoid process of the sphenoid bone as landmarks in our modified endoscopic vidian neurectomy.
conclusionThis study describes a modified surgical approach for endoscopic vidian neurectomy that improves the accuracy and safety of the procedure by locating the vidian nerve without opening the sinuses or exposing the sphenopalatine foramen.
