Background and Objectives: Endoscopic repair of cerebrospinal fluid (CSF) leak can avoid morbidity of open approachesand has shown a favorable success rate. Free mucosal graft is a good method, and multi-layered repair is more favorable. Theinferior turbinate has been commonly utilized for the free mucosal graft, but we newly designed it as a bone-periosteal-mucosalcomposite graft for multilayered reconstruction. Subjects and Method: Four subjects with a skull base defect were treated with this method. The inferior turbinate was partiallyresected including the conchal bone and was trimmed according to defect size. Both bony parts and periosteum were preservedon the basolateral side of the mucosa as a composite graft. The graft was applied to the defect site using an overlay technique. Results: All cases were successfully repaired without any complications. Three of them had a defect size greater than 10-12mm, and the graft stably repaired the CSF leakage. Conclusion: Endoscopic repair of CSF leakage using inferior turbinate composite graft is a simple and easy method andwould be favorable for defect sizes greater than 10 mm.
