How I do it: modification of the posterior pedicled nasoseptal flap for clival and nasopharyngeal surgery

Raewyn G. Campbell, Bradley A. Otto, Daniel M. Prevedello, Ricardo L. Carrau


The posterior pedicle nasoseptal flap, also named the Hadad-Bassagaisteguy flap, was developed at the University of Rosario, Argentina by Hadad and Bassagaisteguy, and modified by Carrau with the aim to design a better intranasal vascular pedicled flap for skull base reconstruction (1,2). The posterior pedicle nasoseptal flap provides an ample surface area with a superior arc of rotation and is therefore a reliable flap, especially for the reconstruction of large skull base defects.
