Endoscopic Endonasal Transphenoidal Approach for Pituitary Adenomas: Outcomes of Our Center

Objectives: Report the results of a consecutive series of patients who underwent an endoscopic endonasal transphenoidal approach (EETA) for resection of a pituitary adenoma. Methods: A retrospective review of patients who underwent EETA at our center between 2010 and 2013, in a collaboration between head and neck surgeons and neurosurgeons, and a description of the technique used. Results: Nineteen patients underwent an EETA for removal of a pituitary adenoma. Decreased visual acuity or a visual field defect was the presenting complaint in 63.2% patients and headache in 26.3%. Nonfunctioning adenoma was the most frequent (52.6%). Sixteen (84.2%) patients had a macroadenoma (>1 cm) and 3 (15.8%) had a microadenoma (
