Objective: We aimed to share our long-term surgical outcomes in 25 patients with intraventricular lesions who underwent surgery via transcortical, interhemispheric, telovelar, and transvermian approaches.Materials and Methods: This study was conducted as a retrospective analysis of patients who underwent surgery for intraventricular brain tumors at our institution between September 2016 and January 2025. Patients were operated using the Kinevo 900 (Carl Zeiss Meditec, Oberkochen Germany) with intraoperative administration of sodium fluorescein, and an optical neuronavigation system (Stealth-Station S8, Medtronic, Minneapolis, MN, USA) was used in all cases.Results: The study population consisted of 14 females (56%) and 11 males (44%), with a mean follow-up period of 64.4 months. The most frequent diagnosis was colloid cyst, observed in six patients (24%). Other common tumor types included meningiomas (four patients, 16%), pilocytic astrocytomas (three patients, 12%), ependymomas (three patients, 12%), subependymomas (two patients, 8%), and central neurocytomas (two patients, 8%). Less frequent pathologies were medulloblastoma , lymphoma , solitary fibrous tumor , diffuse astrocytoma, and H3K27 altered diffuse midline glioma, (each in one patient and 4%). Surgical approaches included transcortical (n=10, 40%), interhemispheric (n=10, 40%), telovelar (n=4, 16%), and transvermian (n=1, 4%). According to the postoperative MRI findings, gross-total resection was achieved in 24 patients (96%), and subtotal resection in one patient (4%).Conclusion: Intraventricular tumors can be safely resected with favourable outcomes when the surgical approach is individualised based on tumor location and patient anatomy. Our high gross-total resection rate and low complication rate demonstrate that maximal safe resection constitutes the mainstay of treatment.
