Clinical characteristics of acromegalic patients with empty sella and their outcomes following transsphenoidal surgery.

abstract：OBJECTIVES:Although the effectiveness of gamma knife radiosurgery (GKRS) in controlling the size of pituitary adenomas has been well demonstrated in many studies, the time period in which significant changes in tumor size occurs has been investigated in a limited fashion. It is important to determine the therapeutic wi...
