Random nasoseptal flap for revision skull base reconstruction. [PDF]

J Clin Neurosci, 2019
The nasoseptal flap (NSF) has become the workhorse of endoscopic skull base reconstruction (ESBR). With the increase in endoscopic skull base procedures, there has also been the need for staged and revision procedures where the use of the NSF is no longer an option. These cases have posed new and interesting challenges to skull base surgeons especially

Aerodynamic and performance characteristics of a passive leading edge Kruger flap at low Reynolds numbers [PDF]

, 2012
An experimental and numerical study was performed on a Clark Y aerofoil with a 10% chord leading edge Kruger flap to examine its aerodynamic performance at Reynolds numbers of 0.6 × 106, 1 × 106, and 1.6 × 106, to help to identify the forces and ...

Nasoseptal “Rescue” flap: A novel modification of the nasoseptal flap technique for pituitary surgery [PDF]

The Laryngoscope, 2011
AbstractObjectives:The introduction of the pedicled nasoseptal flap (NSF) has decreased postoperative cerebrospinal fluid (CSF) leak rates from >20% to <5% during expanded endoscopic skull base surgery. The NSF must be raised at the beginning of the operation to protect the posterior pedicle during the expanded sphenoidotomy.
