nasoseptal flap
Pronunciation: NAY-zo-sep-tal flap
Pedicled flap from nasal septum used for skull base reconstruction after endoscopic tumor resection.
Full Definition
The nasoseptal flap is a vascularized pedicled flap harvested from the nasal septum, primarily based on the sphenopalatine artery. This flap has become the workhorse for skull base reconstruction following endoscopic resection of sinonasal and skull base tumors. The flap provides reliable coverage of dural defects and helps prevent cerebrospinal fluid leaks. Its blood supply, ease of harvest, and excellent reach make it ideal for reconstruction of various skull base defects. Proper flap design and preservation of the pedicle are crucial for successful outcomes.
Usage
Usage note: Document flap dimensions and pedicle preservation when describing nasoseptal flap harvest.
