Abstract

Background: Endoscopic sinus surgery is a well-established treatment for chronic rhinosinusitis in patients with cystic fibrosis, though its benefits seem to be limited to improving sinonasal symptoms rather than affecting lung function. Objective: This study aims to identify clinical and demographic factors that may influence sinonasal and pulmonary outcomes after surgery. Methods: This is a six-year retrospective analysis of adult cystic fibrosis patients who underwent endoscopic sinus surgery at a tertiary care center. 22-Item Sino-Nasal Outcomes Test scores and mean forced expiratory volume data at baseline and three to six months after surgery were analyzed using t-test and stepwise regression with the following covariates: age, gender, lung transplant, revision surgery, and pseudomonas on sinus culture. Results: 119 surgeries were performed on 88 patients, with 69% on patients with transplant. The overall mean (Standard Deviation) improvement in 22-Item Sino-Nasal Outcomes Test score was 9.42 (18.15) for the entire cohort (P <.001). Pseudomonas on culture was associated with less improvement in sinonasal scores (P =.002). There was no significant change in forced expiratory volume after surgery (P =.94). Revision surgery (P =.004) and older age (P =.007) were associated with less favorable change of pulmonary function on stepwise regression (P =.002). There was no correlation between change in sinonasal scores and pulmonary function. Conclusion: Although surgery was associated with a clinically and statistically significant improvement in sinonasal scores in cystic fibrosis patients, patients with pseudomonas may experience less benefit. Revision surgery and older age may be associated with less favorable pulmonary outcomes. Awareness of such variables may help when deciding which cystic fibrosis patients should undergo surgery.
