Endoscopic Endonasal Approach to Pituitary Adenomas

Abstract

Microscopic transsphenoidal surgery is beyond any doubt a widely accepted and highly effective therapy for pituitary adenomas. Currently several centers have converted to an endoscopic transsphenoidal approach; suggesting that this technique provides more complete tumor resection, better visualization and reduce complications. However, there have been few series to document the results of this procedure. This report presents the technical details and compares it to the results of the microscopic method based on the experience of the group and a literature review. The endoscopic transnasal/ transsphenoidal technique is a safe and effective method for removal of pituitary adenomas. The results found in the literature suggest that the endoscope provides more complete tumor removal, and reduces complications. We believe that the advantages of the endoscopic technique will allow this procedure to become the future gold standard surgical therapy for pituitary adenomas.
