Predictors of disease progression after endoscopic sinus surgery in patients with chronic rhinosinusitis.

OBJECTIVE

This study aimed to determine the predictors of disease progression after functional endoscopic sinus surgery in patients with chronic rhinosinusitis.

METHOD: A total of 281 adult chronic rhinosinusitis patients who underwent primary bilateral functional endoscopic sinus surgery between 2007 and 2017 and had at least 12 months of follow-up endoscopic evaluation were examined. Patients were divided into eosinophilic (n = 205) and non-eosinophilic chronic rhinosinusitis groups (n = 76). In order to determine adverse factors, post-operative endoscopic appearance scores were analysed in relation to the pre- and intra-operative findings using multiple regression analyses.

RESULTS

The post-operative course of eosinophilic cases deteriorated over time, like the early period for non-eosinophilic cases. Frontal sinus polyps recurred early in eosinophilic chronic rhinosinusitis. Multivariate analyses indicated young adulthood, asthma, high computed tomography score and frontal sinus polyps as significant adverse predictors.

CONCLUSION

Early, appropriate estimation of sinonasal conditions appears to be crucial for successful surgical management of chronic rhinosinusitis.
