AIM: The third ventricle is located deep in the brain and is adjacent to important neurovascular structures. This makes tumor resection in this region difficult and causes more postoperative complications than surgeries in other regions of the brain. The objective of this study was to investigate the feasibility and clinical effects of transcallosal-interforniceal approach for microsurgical removal of the third ventricle tumors.
METHODS: After preoperative evaluation, 23 patients with the third ventricle tumors were microsurgically operated using the transcallosal-interforniceal approach.
RESULTS: Of these 23 patients, 12 (52.2%) underwent total excision, 9 (39.1%) had subtotal resection, and the remaining 2 (8.7%) underwent partial excision. After surgery, the following complications were observed: diabetes insipidus (11 patients), hemorrhages of the upper digestive tract (2 patients), central fever (1 patient), and memory impairment (1 patient). No mortality in the perioperative period was reported.
CONCLUSION: The surgical procedure using the transcallosal-interforniceal approach is direct and provides good surgical field exposure and fewer post operational compilations. This approach should be considered as the method of choice for surgical removal of the third ventricle tumors.
