Abstrakt:	Background and Objectives: The impact of prior local therapies, including radiation and surgery, on reconstruction outcomes after endonasal surgery is currently not well known. Reconstruction nuances in the preoperative setting merit further evaluation to avoid potential postoperative complications that can hinder overall tumor management and negatively impact patient outcome. We sought to determine whether prior treatments increase risk of reconstruction-related postoperative morbidity and to evaluate the effectiveness of our current treatment paradigm for skull base reconstruction. Methods: A retrospective review of all endonasal surgeries for tumor resection between March 2000 and March 2022 was performed. Patients were grouped based on treatment history. Patient demographics, operative, and postoperative reconstruction-related morbidity data were collected, including cerebrospinal fluid leak, sinonasal morbidity, and infectious complications. Variables significantly associated with postoperative complications in the univariate analysis were included in the multivariate Cox proportional hazards regression model. Complication-free survival curves were generated, and the log-rank test evaluated the relationship between complication-free survival and the different clinical, surgical, and treatment parameters. All statistical analyses were performed with SPSS 26 (IBM Corp) and Graph Pad 9.0 (GraphPad Software). Results: A total of 418 patients were included. 291 patients had no prior treatments, 49 patients had previously received radiation, and 78 patients had prior surgeries. Of the 49 patients who had prior radiation, 27% underwent reconstruction with tunneled pericranial flaps vs 16% of treatment-naïve patients. On multivariate analysis, prior treatment was not significantly associated with reconstruction-related complications. Negative smoking history, no leak or small intraoperative leak, and use of vascularized flap in reconstruction were protective factors. Conclusion: In patients undergoing endonasal surgery, prior radiation and/or surgery does not appear to significantly increase the risk of immediate or delayed reconstruction complications using our current reconstructive management plan, which incorporates an upfront regional flap for high-risk cases.
