Endoscopic One-Nostril Transseptal Transsphenoidal Approach for Pituitary Tumors: Back to the Past—A Multi-Center Preliminary Experience and Literature Review
Simple Summary This study presents the Endoscopic One-Nostril Transseptal Transsphenoidal Approach (EONOTTA) as a minimally invasive surgical technique for selected cases of pituitary macroadenomas. Derived from the classic endoscopic endonasal approach, EONOTTA allows excellent exposure of the sellar region while preserving nasal mucosa and olfactory function. The technique offers comparable disease control to standard endoscopic endonasal approaches, with reduced sinonasal morbidity and postoperative discomfort. Despite limitations such as retrospective design and small sample size, findings support EONOTTA as a safe, efficient alternative for non-extended pituitary tumors requiring limited surgical exposure.
