Layered sellar reconstruction with avascular free grafts: Acceptable alternative to the nasoseptal flap for repair of low-volume intraoperative cerebrospinal fluid leak

摘要

Background: Although the nasoseptal flap has become the method of choice for reconstruction of intraoperative cerebrospinal fluid (CSF) leak in endoscopic minimally invasive surgery of the skull base, layered avascular graft techniques, including allografts and middle turbinate mucosal autografts, may provide comparable reconstructive success with decreased nasal morbidity.
