Risk factors of postoperative trigeminal neuropathy in surgical treatment of trigeminal schwannomas.
Article in Acta neurochirurgica, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
objectiveTrigeminal schwannomas are rare benign tumors originating from the Schwann cells of the trigeminal nerve. Despite the common occurrence of trigeminal neuropathy in trigeminal schwannomas, a detailed analysis has not yet been performed because of the rarity of this disease. This study aimed to analyze trigeminal neuropathy in trigeminal schwannoma resection and identify the risk factors for postoperative worsening of trigeminal neuropathy.
methodsA retrospective analysis of 86 surgical cases was performed at our institution between 1975 and 2018. Obtained parameters included age, sex, diagnosis, reoperation, tumor size, tumor location, presence or absence of cysts, surgical approach, degree of tumor removal, and pre/postoperative trigeminal neuropathy. Uni- and multivariate analyses were performed to identify the risk factors for worsening postoperative sensory disturbances.
resultsOf 83 patients, 58.1% had preoperative trigeminal neuropathy. Postoperative sensory disturbance occurred in 27.9%, with worsening in two cases and de novo symptoms in 22 cases. Regarding risk factors for worsening postoperative sensory disturbances, older age, smaller tumor size, middle and posterior (MP) type, gross total removal (GTR), and anterior transpetrosal approach were identified in the univariate analysis, while MP type and GTR were identified in the multivariate analysis.
conclusionsThis study analyzed trigeminal neuropathy in trigeminal schwannomas in detail and identified tumor location and removal rate as risk factors for worsening postoperative sensory disturbances. Treatment strategies to reduce the risk of trigeminal neuropathy should be considered.
