Abstract

Objectives Operative time, previously identified as a risk factor for postoperative morbidity, is examined in patients undergoing benign cranial nerve tumor resection. Design/Setting/Participants This retrospective cohort analysis included patients enrolled in the ACS-NSQIP registry from 2007 through 2013 with a diagnosis of a benign cranial nerve neoplasm. Main Outcome Measures Primary outcomes included postoperative morbidity and mortality. Readmission and reoperation served as secondary outcomes. Results A total of 565 patients were identified. Mean (median) operative time was 398 (370) minutes. The 30-day complication, readmission, and return to the operating room rates were 9.9%, 9.9%, and 7.3%, respectively, on unadjusted analyses. CSF leak requiring reoperation or readmission occurred at a rate of 3.1%. On multivariable regression analysis, operations greater than 413 minutes were associated with an increased odds of overall complication (OR 4.26, 95% CI 2.08-8.72), return to the operating room (OR 2.65, 95% CI 1.23-5.67), and increased length of stay(1.6 days, 95% CI 0.94-2.23 days). Each additional minute of operative time was associated with an increased odds of overall complication (OR 1.004, 95% CI 1.002-1.006) and increased length of stay (0.006 days, 95% CI 0.004-0.008). Conclusion Increased operative time in patients undergoing surgical resection of a benign cranial nerve neoplasm was associated with an increased rate of complications.
