Anatomic Considerations in Endoscopic Pituitary Surgery

Abstract

The pituitary gland is a small gland at the base of the skull controlling many physiologic processes through its regulation of primary endocrine glands. Pathologies of the pituitary gland and sellar space are wide ranging and most commonly include pituitary adenomas but can also encompass pituitary hyperplasia, other benign nonadenomatous tumors, cysts, and primary and metastatic malignancy. At present, the endoscopic approach has been established as a safe and effective approach to surgical management of pituitary pathology. A detailed understanding of the sella and parasellar anatomy from an endoscopic approach is imperative to performing safe endoscopic surgery in this area.
