Figure 1: Illustration of technique of endoscopic repair of CSF leak in patients with cribriform defect (a), ethmoid defect (b). The technique for visualization of sphenoid recess in patients with sphenoid encephaloceles has been illustrated (c). Intraoperative photograph (d) Fascia lata graft being laid over the skull base defect, which has been covered with fat and fibrin sealant after defining the margins of the defect and removal of mucosa around it. CSF = Cerebrospinal fluid
