Although the etiology of CRS is considered multi-factorial without one single unifying factor, several studies have investigated the role of a septal deviation as a predisposing factor of CRS. A systematic review and meta-analysis quantified the outcomes and concluded that there was statistical evidence for the association between CRS and septal deviation, especially those with a septal deviation angle > 10-degrees. However, the clinical relevance of septal deviation as an etiologic factor for CRS is still unknown.
