Abstract
INTRODUCTION: Watertight reconstruction to separate the intradural compartment from the sinonasal cavities is crucial after endoscopic resection with transnasal craniectomy (ERTC) for naso-ethmoidal tumors. Three-layer reconstruction with the iliotibial tract (TRITT) is a safe and reliable alternative when vascularized flaps are not available.
SURGICAL TECHNIQUE: The iliotibial tract graft is harvested on the lateral aspect of the thigh and divided in three portions, which are positioned in a multi-layered fashion to close the skull base defect. The first layer is disposed intracranial intradural, the second intracranial extradural, and the third extracranial. Fat grafts from thigh subcutaneous tissue are placed between the second and third layer to fill the dead space between them. Use of fibrin glue and intradural irrigation may help the surgeon to stabilize the layers during reconstruction.
CONCLUSION: TRITT is a feasible, highly reproducible, safe, and always available option for reconstruction of anterior skull base defects after ERTC for naso-ethmoidal tumors.
