Characteristics and prognostic analysis of cystic vestibular schwannomas: prolonged surgical duration with limited impact on neurological function.
Article in Frontiers in oncology, 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
Introduction: This study aims to evaluate the differences between cystic vestibular schwannomas (CVS) and solid vestibular schwannomas (SVS) with respect to imaging characteristics, surgical duration, gross total resection (GTR) rates, and postoperative neurological functional outcomes. The goal is to inform individualized surgical planning and perioperative management. Methods: A retrospective analysis was conducted on 273 patients who underwent surgery for vestibular schwannomas. Patient data were divided into CVS and SVS groups. Comparisons were made regarding tumor volume, surgical duration, GTR rates, and postoperative preservation of facial nerve function and hearing. Multivariate analysis was used to identify independent predictors for postoperative functional outcomes. Results: The findings revealed that CVS cases had larger tumor volumes and longer surgical durations (96.6 minutes vs. 87.5 minutes) compared to SVS. Additionally, the rates of postoperative facial nerve function preservation and hearing preservation were lower in the CVS group, while no significant difference was found in GTR rates between the two groups. Multivariate analysis identified tumor volume and patient age as independent predictors of postoperative functional outcomes, whereas cystic changes had a limited impact on prognosis. Discussion: These results underscore the importance of thorough preoperative assessment of tumor volume and cystic characteristics in vestibular schwannomas. Evaluating these factors can optimize individualized surgical strategies and perioperative management, with the aim of improving postoperative functional outcomes for patients.
