Long-term Control in Rhinosinusitis After Functional Endoscopic Sinus Surgery (FESS)

Long-term Control in Rhinosinusitis After FESS: Cross-sectional Observational Study on Control in Rhinosinusitis at a Mean Interval of 3 Years After FESS

State-of-the-art documents like ARIA and european position paper on rhinosinusitis (EPOS) provide clinicians with evidence-based treatment algorithms for allergic rhinitis (AR) and chronic rhinosinusitis (CRS) respectively (1)(2) . The currently available medications can alleviate symptoms associated with AR and RS, and most patients with RS benefit from endoscopic sinus surgery (ESS). In real life, a significant percentage of patients with AR and CRS continue to experience bothersome symptoms despite adequate treatment. This group with so-called severe chronic upper airway disease (SCUAD) represents a therapeutic challenge (3).
