nasoseptal flap
A vascularized mucoperiosteal flap harvested from the nasal septum used for skull base reconstruction.
Full Definition
The nasoseptal flap is a pedicled vascularized flap based on the posterior septal artery, commonly used in endoscopic skull base surgery for reconstruction of dural defects. The flap consists of mucosa, submucosa, and periosteum harvested from the nasal septum and can be rotated to cover defects in the anterior, central, or posterior skull base. This technique has revolutionized endoscopic skull base surgery by providing reliable, well-vascularized tissue for reconstruction, significantly reducing cerebrospinal fluid leak rates.
