Overview

The transsphenoidal microsugrical approach is the mainstay of treatment for growth hormone-(GH) producing, adrenocorticotropic hormone-(ACTH) producing, and endocrine-inactive adenomas.

Surgery

Surgical treatment and surgical contraindication for pituitary adenoma:

• The transsphenoidal microsurgical approach to a pituitary lesion is the most widely employed surgical approach to pituitary lesions and represents a major development in the safe surgical treatment of both hormonally active and nonfunctioning tumors.
• This approach is often successful in debulking tumors, even those that have a significant suprasellar extension.
• A contraindication to this approach includes tumors with a significant suprasellar extension with an hourglass-shaped narrowing between the intrasellar and suprasellar component because blind attempts to reach the suprasellar tumor may lead to cerebral damage.
• An infection in the sphenoid sinus is potentially a contraindication to the transsphenoidal approach
