Objectives: The aim of the research is to examine the correlation of the demographic factors (age and gender), consciousness of patients at admission, tumor location, the extensiveness of the surgical removal and histological grade of the tumor with the final outcome of the surgical treatment of cerebral convexity meningioma. Study Design: The research is a cross-sectional study. Patients and methods: The research included all patients diagnosed with cranial vault meningioma, treated at the Department of Neurosurgery, University Hospital Centre Osijek from 2000 to 2015. Data were taken from patients’ medical history. The outcome of the treatment was defined by the Karnofsky Performance Index (KPI) and Glasgow Outcome Scale (GOS). Results: There was a total of 134 patients included in the research, 71.6 % were female and 28.4 % male. The median age of patients was 64.0. Indicators of treatment outcomes, KPI and GOS were significantly associated with age (p < 0.001), the admission consciousness (p < 0.001), Simpson degree of extensiveness of the tumor surgical removal (p < 0.001) and tumor location (p = 0.049; p = 0.033). There was a statistically significant correlation between histological grade of the tumor and GOS indicators of outcome (p = 0.036). Conclusion: Patients’ gender does not influence the outcome of the treatment. Younger patients and those with preserved consciousness indicate generally better treatment outcome. Patients with more conveniently localized tumor and those with the tumor completely removed have more favorable treatment outcome. Patients with histologically benign tumors have more favorable treatment outcome, determined by GOS values. The most valuable predictors of the surgical management outcome of convexity meningioma are: patients’ age and state of consciousness at admission, tumor localization, and extensiveness of the tumor surgical resection.
