BackgroundWith the advancement of endoscopic endonasal surgery in the treatment of anterior skull base (ASB) pathologies, extended, watertight reconstructions are needed to prevent cerebrospinal fluid (CSF) leakage. This often involves the use of multilayers closure, with free fascia lata (FL) graft frequently used as an in- and/or outlay. However, positioning the FL properly can be challenging and time-consuming, particularly on wider defects. In this technical note, we present an easier and faster way to position FL using a silicone sheet.MethodsFL graft is harvested using a standard technique. The required dimensions are evaluated depending on the extent of the dural defect taking in consideration that FL graft should exceed the edges of the dural defect especially laterally. It is then wrapped around a semi rigid pattern (Silastic sheet) and secured with several monofilament 5/0 sutures. The "package" is transferred through the endonasal corridor to the defect. The sutures are divided and taken out; the fascia is unfolded, and its edges are inserted into the subdural space without any twisting or folding of the flap. Finally, the silicone sheet is withdrawn from the nasal cavity, leaving the FL well-stretched in perfect position.ResultsWe illustrate this technique in the management of a large anterior skull base chondrosarcoma, which necessitated significant bone and dural resection.ConclusionsThe "Gift wrap" technique offers an alternative approach for positioning the FL, which is less time-consuming compared to the traditional technique. Moreover, it enables improved placement of the FL, enhancing its efficacy.Copyright © 2023 Elsevier Inc. All rights reserved.
