What this Trial Is About

Researchers are examining the effects of endoscopic sinus surgery on individuals with cystic fibrosis who also have chronic rhinosinusitis (CRS). This observational study compares patients who undergo sinus surgery to those who receive only medical treatment for CRS. The study aims to understand how surgery impacts pulmonary health, quality of life, and other related outcomes in this population. Participants will be grouped into those who have endoscopic sinus surgery and those who continue with medical therapy without surgery. The study follows patients over time, capturing changes from baseline through 3, 6, 9, and 12 months. Both groups are observed to provide a comparison of pulmonary function, hospitalizations, quality of life, and sense of smell. During the study, participants will undergo evaluations at multiple time points including baseline, 3, 6, 9, and 12 months. These assessments include pulmonary function tests, tracking hospital days, quality of life questionnaires, and olfaction measurements. The research team will monitor these outcomes to understand the longer-term effects of sinus surgery versus medical management in cystic fibrosis patients, with total participation lasting up to one year.
