Abstract

Abstract: Objectives: Sinonasal and skull base tumors are rare, making it difficult to identify trends in surgical outcome. This study examines complications in a large cohort of patients undergoing surgery for sinonasal malignancy. Methods: Following IRB approval, an institutional database was reviewed to identify patients who underwent surgery for sinonasal or skull base malignancies from 1973 to 2016 at our institution. Charlson comorbidity index score and Clavien–Dindo grade were calculated. The main study endpoint was subgroup analysis of Clavien–Dindo Grade 0, Grades 1–2, and Grades 3–5 complications. An ordinal logistic regression model was constructed to assess the association between comorbidities, demographics, tumor characteristics, and surgical complications. Results: In total, 448 patients met inclusion criteria. Perioperative mortality rate at 30 days was 1.6% ( n = 7). The rate of severe complications (Clavien–Dindo 3 or higher) was 13.6% ( n = 61). Multivariate analysis using an ordinal logistic regression model showed no association between Charlson comorbidity index score and Clavien–Dindo grade of postoperative complication. Advanced T‐stage was significantly associated with complications ( p = 0.0014; odds ratio: 3.442 [95% confidence interval: 1.615, 7.338]). Conclusion: Surgery for sinonasal and skull base tumors is safe with a low mortality rate. Advanced T‐stage is associated with postoperative complications. These findings have implications for preoperative risk stratification. Key Points Surgery for sinonasal malignancy is safe with a 30 mortality of 1.6% and rate of severe complications of 12.8%. There is no association between patient comorbidity and post operative complication. On multivariate analysis, only advanced T stage was associated with increased rate of surgical complication.
