Abstract
‐Surgical repair is required for persistent CSF leaks due to trauma or following endoscopic skull base resections ‐The endoscopic endonasal approach is associated with low morbidity and high success rates; 90% at first attempt and overall in 97% ‐A variety of materials are used for the reconstruction and closure of CSF leaks with no overall consensus; the multilayered approach to defect closure is currently deemed best practice ‐The anterior ethmoid septal flap can be successfully utilized for frontal CSF leak repair ‐Anterior ethmoid flap is conveniently located for frontal sinus defects; and so provides excellent final layer of multilayer reconstruction when septum is intact
