  • Title: Cross-reinforcing suturing and intranasal knotting for dural defect reconstruction during endoscopic endonasal skull base surgery.
    Author: Heng L, Zhang S, Qu Y.
    Journal: Acta Neurochir (Wien); 2020 Oct; 162(10):2409-2412. PubMed ID: 32418133.
    Abstract:
    BACKGROUND: With technical improvement, accumulating lesions could be resected using endoscopic endonasal surgery. However, cerebrospinal fluid leakage is still a concern. Intraoperative dural defect reconstruction is critical. METHOD: We developed a new knotting technique for dural closure during endoscopic skull base surgery. We presented a step-by-step description of the fascia lata inlay and autologous dural patch intermittent suturing method following cross-reinforcing principles and emphasized the key points of the novel intranasal knotting technique. CONCLUSION: The new intranasal knotting and suturing technique is a feasible method to close the dura and to prevent cerebrospinal fluid leakage.
