Lengthening the Nasoseptal Flap Pedicle with Extended Dissection into the Pterygopalatine Fossa: A Cadaveric Anatomic Study

Releasing the nasoseptal flap (NSF) pedicle from the sphenopalatine artery (SPA) foramen may considerably improve flap reach and surface area. Our objectives were quantify increases in pedicle length and NSF reach through extended pedicle dissection into the pterygopalatine fossa (PPF) through cadaveric dissections and present clinical applications.
