Objective: This study aimed to elucidate the revision rate, time to revision, and factors associated with revision of endoscopic sinus surgery (ESS) in Taiwan.
Design: Retrospective study.
Setting: Population-based analysis.
Participant: We identified all in-hospital patients, aged >20 years, who underwent ESS between 2000 and 2008 from the Taiwan National Health Insurance Research Database, and followed up with them until 2018.
Main outcome measures: Factors associated with revision surgery were analyzed using multivariable Cox proportional hazard model.
Results: Overall, 66 592 patients were identified (mean age, 46.3 years; 62% males). The revision rate was 14.5% (9644/66 592) and time to revision surgery was 5.9 years. Multivariable Cox proportional hazard model showed that young age, male gender (hazard ratio [HR] = 1.18; 95% confidence interval [CI], 1.13-1.23), having nasal polyposis (HR = 1.17; 95% CI, 1.12-1.22), having allergic rhinitis (HR = 1.08; 95% CI, 1.04-1.13), having asthma (HR = 1.26; 95% CI, 1.14-1.39), and surgical time of >4 h (HR = 1.11; 95% CI, 1.06-1.16) were associated with increased risk of revision surgery. Concurrent septal surgery (HR = 0.81; 95% CI, 0.76-0.87), turbinate surgery (HR = 0.91; 95% CI, 0.85-0.97), or septal and turbinate surgery (HR = 0.68; 95% CI, 0.64-0.73) were associated with decreased risks of revision surgery.
Conclusion: In Taiwan, risk factors for revision ESS are young age, male gender, having nasal polyposis, having allergic rhinitis, having asthma, and long surgical times. Concurrent septal or turbinate surgery decreases the risk of revision.
