OBJECTIVE: Reconstruction of the skull base using a pedicled nasoseptal @entity1912 (NSF) seems to be advantageous after the endoscopic endonasal transsphenoidal approach (EETSA). A few reports have evaluated the cause of @entity1912 failure in EETSA using NSFs. The aim of this study was to evaluate the perioperative risk factors for NSF failure. STUDY DESIGN: @entity1 series. SETTING: Retrospective review of medical records at a tertiary referral center. METHODS: The study population comprised @entity1 who underwent EETSA with NSF elevation between February 2009 and March 2014. The authors retrospectively reviewed the all @entity1 ' medical records, including operative findings. RESULTS: Four hundred thirteen @entity1 (203 males and 210 females) underwent EETSA, and 315 @entity1 underwent EETSA with NSF elevation. The mean @entity1 age was 48.0 years. The total number of @entity1 of NSF failure was 6 (overall rate: 1.61%, 6/315; @entity1912 elevation: 0.31%, 1/315; @entity1912 reconstruction: 15.1%, 5/33). Two @entity1 had @entity6 . One @entity1 had @entity65 . Five @entity1 were elderly (>60 years; mean age: 70 years). Five @entity1 had postoperative @entity281 . One @entity1 underwent preoperative radiation therapy. CONCLUSION: Nasoseptal @entity1912 is a usually safe and effective technique for skull base reconstruction. However, the management of @entity1 with @entity6 , @entity65 , advanced age, postoperative @entity281 , and radiation therapy may require more attention to improve NSF survival.
