Among 100 consecutive CRSwNP patients undergoing ESS in 2021 with postoperative topical steroid irrigations, including 75 revision surgeries, SNOT\u201022 scores improved at 6\u00a0months postoperatively, with durable and consistent improvement at 24\u00a0months (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001).

SNOT\u201022 scores for primary ESS patients and patients with a preoperative CoSI score of less than 70 improved by 26.4 and 28.1 points, respectively, in contrast to patients with a preoperative CoSI of 70 or greater (14.1 points, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.029).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>It is important to define extent of surgery in CRSwNP to stratify postsurgical patients based on likelihood to benefit from revision surgery or alternative medications.
