This prospective cohort study evaluated chronic rhinosinusitis patients aged 5-18 years undergoing endoscopic sinus surgery in terms of quality of life. General and chronic rhinosinusitis surveys were completed by the parents and the child pre-ESS and at 30-90 days post-operatively. They found that general quality of life was improved pre-operatively and sinus symptoms improve significantly one to three months after sinus surgery. Parents reported statistically worse chronic rhinosinusitis symptom scores than the children.
