Complication Rates Following Endoscopic Sinus Surgery for Chronic Sinusitis.

Abstract

BackgroundEndoscopic sinus surgery (ESS) is a minimally invasive procedure indicated for medically refractory chronic sinusitis (CRS). As with any surgical procedure, there are potential risks and complications.ObjectiveThe purpose of this study is to report skull base, orbital, and hemorrhagic-associated complication rates following ESS.MethodsA retrospective query on the TriNetX platform identified patients diagnosed with CRS who subsequently underwent ESS in the last 20 years. Outcomes analyses were performed to determine the incidence of skull base (cerebrospinal fluid rhinorrhea, bacterial meningitis, dural tear), orbital (diplopia, optic nerve injury, blindness, epiphora, orbital hemorrhage, canthotomy/canthoplasty), and hemorrhagic (epistaxis, carotid artery injury, blood transfusion) complications within 30 days postoperatively. Kaplan-Meier Analysis estimated survival probability from each complication type. Outcome rates were also compared between female and male patients.ResultsA total of 116 669 patients from 55 healthcare organizations fit the study criteria. The average age at surgery was 47.9 ± 17.9 years. The gender distribution of the cohort was 50% female and 48% male. The risk of skull base, orbital, and hemorrhagic complications within 30 days of the surgery was found to be 0.212%, 0.741%, and 3.00%, respectively. Kaplan-Meier Analysis revealed that survival probability from each complication type was 99.783%, 99.260%, and 96.903%, respectively. Comparison of outcome risks stratified by gender revealed no major differences for skull base and orbital complications; however, males exhibited a significantly higher risk of hemorrhagic complications (3.2% vs 2.8%, P < .0001).ConclusionsThe study supports ESS as a safe procedure for the management of CRS. Though rare, hemorrhagic complications are more common than orbital and skull base complications. Hemorrhagic complications are also more common in men than women. These findings provide insights for counseling patients about ESS risks and benefits.
