Objective: To modify the individual neuroendoscopic surgical approach of pituitary tumors with specific imaging features, and to analyze the clinical outcomes. Methods: The clinical data of 116 patients with pituitary tumors who underwent surgical treatment at the pituitary tumor diagnosis and treatment center of Ruijin Hospital from April 2014 to December 2017 were collected, then the resection effects and complication rates of pituitary tumors from three different kinds of transsphenoidal approaches (e.g. classical single nostril approach, bilateral approach, "one-and-a-half" approach) were compared. Results: Pituitary tumor resection with "one-and-a-half" trans-nasal-sphenoidal approach achieved the same surgical effects with the bilateral approach, which was difficult to resect with the single-nostril classical approach. And it had significant advantages in the average length of postoperative hospitalization ( "one-and-a-half" : 6.9 days, bilateral: 12.5 days, P<0.01), the average postoperation VAS of olfactory retention ( "one-and-a-half" : 8.6, bilateral: 7.0, P<0.01) and preventing posterior nasal septum perforation (the occurrence rate of "one-and-a-half" : 0%, bilateral: 27%). Conclusion: The "one and a half" approach increases the ability to control and completely resect the lesion beyond the medial edge of the internal carotid artery on the same side of the nostril involving endoscope. It is a good supplement and improvement to the bilateral approach.
