[The treatment of 432 patients with pituitary adenomas via transsphenoidal approach].
OBJECTIVE
To study some clinical features of 432 cases of pituitary adenomas treated by transsphenoidal microsurgery between July 1982 and October 1996.


METHODS
Pathological examination, immunohistochemical examination and electronmicroscopic examination were done in 424, 29 and 103 cases respectively.


RESULTS
Hyperprolactinemia was found in many so-called non-functioning adenomas besides in prolactinomas. The dura maters were invaded by tumors in 78 cases (the incidence of dural invasion was 65.5%).


CONCLUSIONS
Hyperprolactinemia is not peculiar to prolactinomas, and differential diagnosis is necessary when hyperprolactinemia exists. The involvement of the dura mater of sellar floor is an important mark that the adjacent tissues were invaded by pituitary adenomas. The outcome of surgical treatment is significantly different between the patients with dural invasion and without invasion.
