Watertight duraplasty is essential for surgical management of traumatic anterior skull base (ASB) dural defect but challenging in the deep and narrow operative corridor. Here, the authors report a trans-defect underlay watertight duraplasty (TDUWD) technique for traumatic ASB dural defect. TDUWD was performed by inserting a free pericranium graft under the dural defect. The diameter of the pericranium graft was larger than the dural defect. The pericranium graft was sutured to the dural defect watertightly in an "inside-to-outside" direction, with the needle not penetrating the inner layer of pericranium graft. The pedicled pericranium flap was used as a second layer of reconstruction. The characteristics, complications, and outcomes of patients who received TDUWD are reported. A total of 29 patients received TDUWD. Immediate postoperative cessation of cerebrospinal fluid (CSF) leak occurred in 28 patients. One patient recovered after lumber drainage. No patient needed a second operation or reported delayed recurrence of CSF leak. No complication related to the surgical technique was observed. Use of TDUWD for traumatic ASB dural defect results in an immediate, 1-stage, and definitive correction of CSF leak and seems to be simple, safe, and reliable for large and deeply located dural defects.
