====== Anterior skull base reconstruction ======

The development and widespread utilization of the [[nasoseptal flap]] has revolutionized [[anterior skull base]] [[reconstruction]]. Before the [[description]] of the nasoseptal flap in [[2006]], other local vascularized flaps such as the pericranial or temporoparietal [[fascia]] flaps were utilized and conveyed potentially unnecessary morbidity to patients. Reconstruction of the [[anterior skull base]] does not always require a vascularized tissue flap and can often be achieved with non-vascularized [[autologous]] or synthetic [[graft]]s. However, large [[skull base defect]]s involving high-flow [[cerebrospinal fluid leak]]s require vascularized tissue [[reconstruction]] to avoid post-operative CSF leak and resultant [[complication]]s. The nasoseptal flap utilizes [[mucosa]] based on a vascular pedicle within the [[nasal cavity]] that minimizes [[morbidity]] and maximizes success for anterior skull base surgical procedures.

The nasoseptal flap, also known as the [[Hadad-Bassagasteguy flap]] (HB flap), was developed at the University of Rosario, [[Argentina]], and the University of [[Pittsburgh]] and was first described in 2006. Since then, there have been many theorized augmentations, proposed expansions, and enhanced indications for its use
