<p>The expansion of endoscopic skull base surgery has resulted in the
creation of large defects that must be repaired to ensure separation of
the cranial vault from the nasal cavity. The workhorse of anterior skull
base reconstruction remains the nasoseptal or Hadad-Bassagasteguy flap.
Despite its success, the nasoseptal flap is limited in its ability to
reach extremely anterior defects including those involving the frontal
break, posterior frontal table, and anterior cribiform plate.
Alternative approaches utilizing anteriorly pedicled flaps have been
described which exploit the vascular supply to the anterior septum and
lateral nasal wall. The diminutive nature of the anterior septal blood
supply has led to the elaboration of a bipedicled anterior septal flap
which is capable of reliable reconstruction of both the frontal beak as
well as posterior frontal table defects. Similarly anteriorly based
inferior turbinate flaps pedicled largely on anterior ethmoid
arborizations have been used successfully to reconstruct anterior
defects. In light of the limitations of the nasoseptal flap, the
addition of anteriorly pedicled flaps to the clinical armamentarium
offers the opportunity to provide vascularized mucosal coverage of
virtually any region of the skull base which can be reached
endoscopically.</p>
