Endoscopic transnasal transsphenoidal approach for craniopharyngioma: report of 6 cases.

We conducted a retrospective study to evaluate outcomes in patients with a craniopharyngioma who were managed via a transnasal transsphenoidal approach. Craniopharyngiomas exhibit histologically benign but "clinically malignant" features. Our study group was made up of 5 patients who underwent a total of 6 operations. The study population included 1 female and 5 males, aged 14 to 50 years (mean: 29.2). The overall rate of near-total tumor removal was 67%, but all patients eventually experienced a recurrence. Revision surgery to correct any severe postoperative complications was not required in any case. We found that the endoscopic transnasal transsphenoidal approach could be a safe and less invasive surgical option for the removal of craniopharyngiomas, although we were unable to remove all tumor or prevent recurrences.
