Predictors of surgical complications in patients with sinonasal malignancy.

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.
