Operative and postoperative outcomes in elderly patients undergoing endoscopic sinus surgery

Chronic rhinosinusitis (CRS) is increasingly common in the elderly population (≥ 65 years old). Compared to their younger counterparts, differences exist in the etiology of CRS and outcomes of Endoscopic Sinus Surgery (ESS) for elderly patients. The aim of this study is to determine if differences in surgical outcomes are present between these two patient populations to facilitate patient pre-operative counseling by their healthcare providers.

Retrospective chart review conducted at a single tertiary care center for patients undergoing ESS between June 2014 and June 2019. Patients were classified into two cohorts (adult and elderly) based on age (< 65 and ≥ 65 years old). Demographics, surgical, and postoperative variables were extracted from our institution's electronic medical records. ANOVA and t-test analysis were performed to determine the presence of significant differences between the two cohorts. SNOT-22 scores were used to determine QOL improvements.

Compared to the adult cohort, elderly patients had significant QOL improvement after surgical treatment (p = 0.001), but had a similar successful response to treatment (p = 0.74). Elderly patients had no difference in the incidence of operative/perioperative complications (p = 0.89) or intraoperative or postoperative bleeding (p = 0.301, p = 0.62), but had an increased incidence of postoperative infection (p = 0.000).

ESS remains an effective treatment modality for the management of CRS, and a safe practice for elderly patients despite the increase in complexity of their medical comorbidities and polypharmacy. QOL improvements are significant, though patient counseling should take into account that improvements may not be as pronounced as in younger patients.
