Transnasal Endoscopic Repair of Cerebrospinal Fluid Rhinorrhea and Skull Base Defect: Ten‐Year Experience

Abstract

The endoscopic approach is safe and effective for the treatment of CSF rhinorrhea, even in the cases not successfully treated by previous neurosurgical approaches. Lumbar drain was suggested for defects in the frontal and sphenoid sinus and defects associated with meningocele or encephalocele. Complete exposure of the defect, appropriate selection of a fitting graft, as well as accurate placement and stabilization of the graft are critical to the success of repair.
