title: Endoscopic endonasal repair of spontaneous CSF fistulae.
abstract: The authors present a fully endoscopic endonasal repair of a spontaneous CSF leak caused by a defect in the anterior fossa floor. Patients were positioned supine in a Mayfield headholder in slight extension. A complete ethmoidectomy was performed to expose the defect. The middle turbinate was removed to increase visualization and allow for more working room. The defect was identified and exposed. A nasoseptal flap was raised and placed over the defect. A free-mucosal graft fashioned from the removed middle turbinate was placed on the nasoseptal donor site. The video can be found here: http://youtu.be/gAN2cvQVXCE.
