[Surgical management of pituitary adenomas by transsphenoidal approach].

In the years 1976-1993 we have performed 90 transsphenoidal approaches for pituitary adenomas. This paper presents a detail report concerning 23 cases, operated in the last 2 years, with CT and NMR documentation. A preoperative visual deficit was very common in this group of patients. In the postoperative period the dramatic improvement of the vision was observed in 86% of cases. In our opinion the transphenoidal approach is very useful for the operation of the tumors with suprasellar expansion.
