Perioperative complications among head and neck surgery patients with COVID‐19

Abstract

BackgroundPatients undergoing surgery for head and neck cancer (HNC) have potentially high perioperative complication rates. Recent studies indicate that preoperative COVID‐19 infection poses increased risk for postoperative complications in other fields. However, to date, there has not been data showing the effect of COVID‐19 on complication rates for HNC. Here, a large database was employed to assess if perioperative COVID‐19 increased the risk of perioperative complications among those undergoing HNC surgery.MethodsA retrospective investigation was conducted using a multi‐institutional research database. Subjects who underwent HNC surgery from January 2020 to September 2022 were identified using the International Classification of Diseases and Current Procedure Terminology codes. Thirty‐day surgical and medical complications were assessed for those diagnosed with COVID‐19 infection from 7 days before or after surgery compared to those who were COVID‐19 negative. Cohorts were propensity scores matched by age, sex, and race.ResultsPerioperative COVID‐19 was present in n = 208 and absent in n = 15 158 subjects that underwent HNC surgery. For unmatched analyses, there was a statistically significant increased risk in the 30‐day postoperative period in COVID‐19‐positive patients for the following surgical complications: surgical site fistula, free tissue transfer (FTT) complication, FTT failure, and death. Additionally, there was a statistically significant increased risk in the 30‐day postoperative period in COVID‐19‐positive patients for the following medical complications: ventilator support, pneumonia, vasopressor, acute renal failure, and myocardial infarction.ConclusionThis large, retrospective populational study suggests HNC patients are at increased risk for death and several perioperative complications. This investigation is the first to address this clinical question.
