Pedicled nasoseptal flap is not the standard of care for skull base defects

Efficacy of the pedicled nasoseptal flap without cerebrospinal fluid (CSF) diversion for repair of skull base defects: incidence of postoperative CSF leaks

“…The most critical element to prevent a postoperative CSF leak is to craft a watertight closure of the skull base defect. Currently, there is no standardized technique for skull base reconstruction,25 and it has been shown that success with skull base defect repair is predicated on a learning curve 4. Numerous successful grafts and techniques for repair of CSF fistulas have been described 24,26–30.…”

“…Although not necessarily the standard of care (4) , the nasoseptal flap is incredibly valuable as an option for the skull base surgeon when performing endoscopic tumour resections. The nasoseptal flap is not exclusively used to repair dural defects.…”

Triple‐layer reconstruction technique for large cribriform defects after endoscopic endonasal resection of anterior skull base tumors

“…First introduced by Hadad and Bassagasteguy in 2006, the vascularized pedicled nasoseptal flap (PNSF) is a sturdy, yet malleable flap that encompasses a large surface area with a flexible arc of rotation, providing excellent coverage of large anterior skull base defects created by EEAs . Although not yet considered the standard of care by some authors, the vascularized PNSF has had significant success in reducing postoperative CSF leaks in recent years (from 15.9% to less than 6%), and is currently the workhorse of endoscopic repair of large skull base defects in many large academic centers …”
