Vagus nerve stimulation in drug-resistant epilepsy: Surgical technique from a tertiary epilepsy center.
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: Drug-resistant epilepsy affects nearly one-third of individuals with epilepsy and is associated with significant morbidity and reduced quality of life. For patients who are not candidates for resective surgery, vagus nerve stimulation (VNS) represents an established neuromodulatory therapy. Despite its widespread use, detailed and standardized technical descriptions of implantation remain limited. This article outlines the surgical technique for VNS implantation developed at a tertiary epilepsy center, emphasizing anatomical landmarks, operative steps, and perioperative considerations to enhance safety and reproducibility. Methods: We provide a step-by-step description of VNS implantation based on institutional practice. The procedure includes patient positioning, identification of cervical landmarks, creation of the subcutaneous generator pocket, cervical dissection with carotid sheath exposure, vagus nerve identification and mobilization, helical electrode placement, lead fixation with strain-relief loop formation, intraoperative impedance testing, and layered wound closure. Technical nuances aimed at minimizing complications and facilitating future revisions are highlighted. Results: The described approach enables consistent vagus nerve identification, secure electrode positioning, and appropriate lead stability while preserving surrounding structures. Standardized incision placement, careful tunnelization, and systematic intraoperative testing contribute to procedural safety and reproducibility. Conclusion: A structured and standardized VNS implantation technique is essential to optimize safety, reduce technical variability, and support the consolidation of epilepsy surgery programs. Detailed reporting of surgical methodology may promote harmonized practice and improve access to neuromodulatory therapies across diverse healthcare settings.
