Soler ZM, et al. - The experts probed into the mean change in the 22-item Sino-Nasal Outcome Test (SNOT-22) across patients who had undergone endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS). The results exhibited marked improvement after ESS. Variation was reported in the magnitude of change, which was disclosed to be affected by several factors including baseline SNOT-22 score, asthma prevalence, and length of follow-up.
