Key Points

This research aims to present the harvesting techniques of the lateral nasal wall flap for skull base reconstruction.
Illustration of harvesting techniques for the lateral nasal wall flap using the posterior lateral nasal artery.
Discussion of circumstances preventing the use of the pedicled nasoseptal flap.
The lateral nasal wall flap is a robust flap with consistent blood supply.
It provides comparable coverage to the traditional nasoseptal flap.
Proves to be a reliable alternative for reconstructive procedures when the nasoseptal flap is not an option.

Abstract

Abstract Background The pedicled nasoseptal flap (Hadad-Bassagasteguy flap, HBF) has been considered as the workhorse for reconstruction of high-flow cerebrospinal fluid (CSF) leak following endoscopic endonasal skull base surgery. However, if the septal mucosa is affected by a tumor or the vascular pedicle is injured due to prior surgery, the use of HBF is precluded. Method We illustrate the harvest techniques of the lateral nasal wall flap (LNWF) based on the posterior lateral nasal artery (PLNA). Conclusion The LNWF is a robust intranasal regional flap with a consistent blood supply and comparable coverage surface, making it a reliable alternative when the HBF is unavailable.
