PurposeComminuted fractures of the anterior skull base can easily cause dural damage, leading to cerebrospinal fluid leakage and retrograde infection. Skull base reconstruction is essential. This study aimed to present a novel and simple technique for repairing skull base defects using a self-made fascia-bone fragments-fascia "sandwich" structure made by fascia, fracture fragments, and sutures.MethodFrom 2018 to 2023, we performed self-made sandwich structures for skull reconstruction in 10 patients with anterior skull base comminuted fractures. After debridement, the intracranial bone fragments of the surgical patient were safely removed. In vitro, the bone fragments were spread between two layers of temporal or broad fascia to form a sandwich structure similar to the size of the bone defect, and the periphery was firmly sutured with sutures. The self-made structure was then filled to the defect and fixed with fibrin glue. The periosteum at the top of the forehead was also turned over to the repair area for covering and fixation. Meanwhile, a facial skin cosmetic suture was performed. Finally, we evaluate the feasibility and efficacy of this technique.ResultsAll 10 patients underwent reconstructive surgery using the self-made fascia-fracture fragments-fascia sandwich structure. Five patients with open wounds on the face also underwent cosmetic revisions. No cerebrospinal fluid leakage occurred in all the patients at discharge as well as 3 months later.ConclusionFor patients with comminuted fracture of the anterior skull base, the fascia-bone fragments-fascia structure could repair the skull base and prevent the occurrence of cerebrospinal fluid.Copyright © 2024 Elsevier Inc.
