White matter microdissection of the lateral aspect of the brain: 2-dimensional video demonstration.
Article in Acta neurochirurgica, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundThe white matter dissection technique owes its modern recognition to Josef Klingler, whose fixation protocol enabled detailed fiber bundle visualization and led to an outstanding and still relevant atlas of white matter anatomy. After a period of decline in the late twentieth century, the technique was reintroduced into neurosurgical training with the aid of the surgical microscope, emphasizing the importance of fiber dissection and its practical applications in clinical neuroanatomy. This article provides a structured, step-by-step demonstration of white matter microdissection, progressing from superficial anatomy to deeper fiber layers. Its main contribution is the supplementary video, which offers a detailed, structured demonstration of the dissection steps and white matter layers, replicating the format and clarity of hands-on dissection courses. Careful editing and post-processing were applied to optimize educational impact.
methodsThe dissection was recorded during the 7th Sulci, Gyri, Ventricles and Fiber Dissection Hands-on Course (Taipei, November 2024). Identifiable participants gave informed consent for publication.
resultsThe video illustrates a systematic lateral-to-medial dissection, beginning with sulcal and gyral identification. Grey matter is removed to expose U-fibers, followed by progressive visualization of the superior longitudinal fasciculus, insular cortex, extreme and external capsules, claustrum, basal ganglia, and anterior commissure. Each step is accompanied by commentary and technical tips to guide the dissection and preserve anatomical integrity.
conclusionBy mastering the topography of white matter, neurosurgeons can enhance their understanding of pathological anatomy, allowing for precise mental rehearsal and strategic planning before surgery. This approach underscores the enduring importance of anatomical studies in improving surgical outcomes and advancing neurosurgical practice.
