Effect of Functional Endoscopic Sinus Surgery on Outcomes in Chronic Rhinosinusitis​

Chronic rhinosinusitis (CRS) has a significant negative impact on quality of life (QoL). Surgical treatment of CRS is indicated when medical therapy fails to achieve adequate symptom control. This review summarizes the latest information on the outcomes after endoscopic sinus surgery (ESS) with relation to QoL, revision rates, olfaction, absenteeism, asthma control, use of systemic medications, quality of sleep and complications. We also provide an update regarding the factors that can impact outcomes.

CRS has classically been divided into two phenotypes depending on the presence or absence of nasal polyps. However, this is an oversimplification as many factors impact disease burden and outcome after treatment. It has been demonstrated that in many cases, ESS fails to meet the expectations of the patients. Evidence based patient counselling is key to help surgeons guide their patients in the best possible way to make well-informed decisions. Repeatedly it has been demonstrated that ESS improves QoL, improves olfaction, leads to better asthma control and less use of systemic antibiotics. However, various patient characteristics including phenotype, disease burden, comorbidities, age, gender and surgical technique can influence the outcome after ESSIt is of paramount importance to include a follow-up period when discussing revision rates. Based on available data, the genuine revision rate is probably 15-20% after five to ten years of follow-up. The revision rate is also affected by various factors and comorbidities.
