Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The aims of the study are: 1)to assess pre and post-operative Quality of Life (QOL) as measured by the Sino-Nasal Outcomes Test(SNOT)-20 questionnaire and 2)determine the significance of response shift on treatment effect. This is a prospective cohort study. The investigators will recruit patients who are within a 6 month post-functional endoscopic sinus surgery (FESS) timeframe and completed a pre-operative SNOT-20. The investigators will ask subjects to complete two more SNOT-20 forms and a Transition Quality of Life (QOL) scale. The SNOT-20 forms will be labelled "pre" and "post" operative. The "pre" should be completed based on subject's memory of their condition prior to surgery and "post" based on how they feel now.
