Surgical outcomes of ventrally located cervical spinal meningiomas.
Article in Spinal cord, 2025. 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
STUDY
designRetrospective cohort study
objectivesVentrally located cervical spinal meningiomas present significant surgical challenges due to their proximity to the spinal cord and nerve roots. This study aimed to evaluate the surgical outcomes of these tumors resected via the posterior approach and to compare them with dorsolaterally located meningiomas.
settingThe single institution in Japan.
methodsA retrospective review was conducted on 39 patients who underwent posterior surgical resection of cervical spinal meningiomas between 2008 and 2023, with a minimum follow-up of one year. Patients were classified into ventral (n = 17) and dorsolateral (n = 22) groups based on tumor localization. Neurological function was assessed using the Japanese Orthopedic Association (JOA) score, and surgical outcomes were compared.
resultsThe groups had no significant differences in operative time or blood loss. However, nerve root resection was significantly more frequent in the ventral group (41.2 vs. 9.1%, p = 0.02), and perioperative complications and intraoperative motor-evoked potential amplitude reduction (35.3 vs. 4.5%, p = 0.03) were more common (41.2 vs. 13.6%, p = 0.06). Although postoperative JOA scores were lower in the ventral group (14.6 ± 0.6 vs. 16.4 ± 0.3, p = 0.01), both groups showed significant postoperative improvement compared to preoperative scores (p < 0.01).
conclusionsDespite the higher risk of nerve root sacrifice and limited neurological recovery associated with the posterior approach, considering the functional improvements from baseline, it remains a viable surgical option for ventrally located cervical meningiomas. Further studies comparing different surgical approaches are needed to optimize treatment strategies.
