The objective of this study was to quantify the effect of endoscopic sinus surgery on pulmonary function in patients with cystic fibrosis and chronic rhinosinusitis.
The PubMed, MEDLINE, Cochrane Library, and Embase databases were searched for studies published in English, without any language and time restrictions from their inception to March 1, 2020. Studies examining pulmonary function outcomes in patients with cystic fibrosis and chronic rhinosinusitis following endoscopic sinus surgery were included. Primary outcomes were pulmonary function tests, including forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), FEV1/FVC, peak expiratory flow (PEF), and forced expiratory flow between 25% and 75% of vital capacity (FEF ).
A total of 12 studies with 570 patients were included for data extraction and meta-analysis. For FEV (%), the summarized mean difference (MD) was -6.92 (95% confidence interval [CI] = -19.67 to 5.83, P = .29) and 0.70 (95% CI = -3.81 to 5.21, P = .76) for the postoperative results after 6 months and 12 months, respectively. The pooled MDs for FVC (%) and FEV1/FVC ratio (%) for the postoperative results after 6 months were 0.60 (95% CI = -4.12 to 5.31, P = .80) and -1.29 (95% CI = -6.14 to 3.55, P = .60).
Endoscopic sinus surgery in chronic rhinosinusitis patients with cystic fibrosis did not improve the pulmonary function in chronic rhinosinusitis patients with cystic fibrosis. More prospective studies and meta-analyses addressing the same topic are needed in the future. Laryngoscope, 2020.
