Nasoseptal Flap Reconstruction of High Flow Intraoperative Cerebral Spinal Fluid Leaks during Endoscopic Skull Base Surgery

The nasoseptal flap is an excellent anterior skull base reconstructive technique. Patients with high-flow intraoperative CSF leaks had a 94% successful reconstruction rate. Patients with skull base proton radiation therapy are at higher risk for flap failure and preparation for nonradiated tissue reconstruction should be discussed with the patient.
