Outcomes of Functional Endoscopic Sinus Surgery in Chronic Rhinosinusitis: A Systematic Review and Meta-Analysis.

Chronic rhinosinusitis (CRS) is a prevalent health problem that affects many people around the world and can require surgical intervention if conservative therapy fails. Functional endoscopic sinus surgery (FESS) is a minimally invasive surgical procedure commonly used to manage CRS. The success of FESS depends on various factors, and larger studies are necessary to determine its efficacy in managing CRS in this population. This systematic review and meta-analysis of the available literature aims to provide a comprehensive assessment of the effectiveness of FESS in the Middle East. We followed the standards outlined by PRISMA and the Cochrane Handbook for systematic reviews. The primary outcome of interest was the quality of life (QOL), and the secondary outcome was the recurrence of CRS. This systematic review and meta-analysis was conducted, and sensitivity analysis was performed to examine the robustness of the results. Six studies were included. The review found that the QOL significantly improved (p < 0.001). Two studies reported recurrence of CRS after FESS, and data showed that the recurrence of CRS after surgery was 6%. FESS is an effective intervention for CRS, but further research is needed on recurrence rates.
