Introduction: The nasoseptal flap has revolutionized endoscopic skull base surgery; however, adequate closure of large dural defects remains technically challenging. The use of a rigid component to form a gasket-seal around the bony defect margin may prove useful in reducing the rate of CSF fistula. Here we describe a modification of the nasoseptal flap, which allows the harvest of cartilage with its blood supply along with mucosa for a stronger repair of large skull base defects.
