In real world practice, ESS is commonly performed in combination with septoplasty despite the lack of a RCT. The lack of level-1 evidence continues to raise questions regarding the true effectiveness and appropriateness of ESS for patients with CRS as opposed to just performing a septoplasty alone. This current gap in the literature provides a strong incentive to evaluate the role of ESS using a RCT design and is the impetus behind this research project.
