Staged transsphenoidal surgery for fibrous nonfunctioning pituitary adenomas with suprasellar extension.
Staged transsphenoidal surgery was performed in seven patients with nonfunctioning pituitary adenomas with suprasellar extension. Remnant adenomas were present in a supersellar position after complete removal of the intrasellar tumor, and did not descend into the sella because of the fibrous nature in five patients or fibrous nature and dumbbell shape in two. Magnetic resonance images were obtained every 2 weeks following initial surgery. ⋯ Patients were followed up over 6 to 58 months (mean +/- SD 24.7 +/- 18.9 months). There were no major surgical complications or recurrence of tumor on follow-up images. Our postoperative imaging studies and surgical results demonstrated that staged transsphenoidal surgery is an effective and safe treatment for fibrous nonfunctioning pituitary adenomas with suprasellar extension.
