- W1981123950 abstract "An extended transsphenoidal approach allowed for direct midline exposure of the parasellar structures such as the hypothalamic-pituitary axis and the third ventricle. To evaluate the capability of this approach for removal of suprasellar craniopharyngiomas, surgical outcomes were retrospectively analyzed.During a 9-year period, 20 consecutive patients with suprasellar craniopharyngioma underwent transsphenoidal tumor resection. The average follow-up period was 55 months. No patient had a purely intrasellar tumor, 9 had prechiasmatic tumors, 9 had retrochiasmatic tumors, and 2 had purely intraventricular tumors.Total resection was achieved in 86% of operations. Even in mostly intraventricular cases, a transsphenoidal trans–lamina terminalis approach afforded complete resection. Visual improvement and preservation of the pituitary stalk were achieved in 84% and 95% of cases, respectively. New postoperative deterioration of pituitary function occurred in about 65% of cases, and no patient resolved their preoperative hormonal disturbance after surgery. The overall percentage of patients with diabetes insipidus increased to 61% postoperatively from 11% preoperatively. Nonendocrinologic surgical complications were observed: worsening of vision in 3 patients, hyperphagia in 3 patients, short-term memory loss in 2 patients, and cerebrospinal fluid leakage in 3 patients. Recurrence after total resection occurred in 2 (11%) patients with retrochiasmatic tumors.Reasonable surgical results in this study suggest that the extended transsphenoidal approach is safe and effective for removal of craniopharyngiomas. Although preservation of the pituitary stalk can be achieved in a high percentage of patients, postoperative endocrinopathy still remains as a significant problem after radical removal of the craniopharyngioma." @default.
