Modified surgical technique for recurrent organized chronic subdural hematoma: a preliminary retrospective case series.
Article in Frontiers in 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
Background: The incidence of chronic subdural hematoma (CSDH) increases with age, and the recurrence rate after burr-hole drainage remains relatively high. The clinical management of recurrent organized CSDH continues to pose a challenge. This study aimed to preliminarily evaluate the safety, neurological improvement, and recurrence control of craniotomy for hematoma evacuation combined with middle meningeal artery occlusion and temporalis muscle grafting in the treatment of recurrent organized CSDH. Methods: A retrospective analysis was performed on 17 patients with recurrent organized CSDH admitted between January 2021 and December 2023, all of whom underwent the above modified procedure. Perioperative parameters were recorded. Neurological function before and after surgery was assessed using the Glasgow Coma Scale (GCS), modified Rankin Scale (mRS), Markwalder grading system, and Glasgow Outcome Scale (GOS). Postoperative complications and hematoma recurrence were monitored during follow-up. Results: Complete hematoma evacuation was achieved in all patients, with improved midline shift and satisfactory brain re-expansion. Neurological function was improved postoperatively, as reflected by optimized GCS, mRS, Markwalder grade, and GOS scores. Postoperative complications occurred in 5 patients (29.41%), including subdural effusion, cerebrospinal fluid leak, secondary intracranial hemorrhage, and epilepsy, all of which resolved with conservative management. No recurrence was observed according to the 90-day postoperative recurrence criteria. No ipsilateral hematoma recurrence or new neurological deficits were noted during 1-year follow-up. Conclusion: In highly selected patients with recurrent organized CSDH, this modified craniotomy technique appears feasible and reasonably safe, with encouraging short-term neurological improvement. No recurrence was observed per the predefined 90-day endpoint; 1-year follow-up was descriptive. This study is a small-sample, single-center, uncontrolled retrospective case series in a highly selected cohort. The results should be interpreted as preliminary safety and feasibility data, and no assertions regarding superior efficacy or recurrence reduction can be made. Large-scale controlled studies are warranted to further validate clinical utility.
