Multilayered Closure of Cerebrospinal Fluid Rhinorrhea with Inlay Fascia Lata, Autologous Fat, and Outlay Fascia Lata: Our Experience

Background/Aims: Since the initial use in 1981 by Wigand, different endoscopic endonasal surgery techniques have been proposed to close ventral skull base defects, all of which include multilayer closure involving vascularized mucoseptal flaps, autologous grafts, and synthetic materials. These methods are used individually or in combination, as required by the operative condition. Methods: In this study we aimed to describe our endoscopic technique using inlay-outlay fascia lata and autologous fat with fibrin sealant to close spontaneous and traumatic cerebrospinal fluid (CSF) rhinorrhea. Results and Conclusion: Twenty-one CSF rhinorrhea patients were operated with this technique in our hospital. Two patients had large skull base defects and 15 patients had high-flow CSF leaks. We reached a 100% success rate in the first attempt without any long-term recurrence. Multilayered endoscopic closure with this technique offers satisfactory results with minimal morbidity even in large defects and high-flow CSF leaks.
