This study aimed to evaluate the efficacy and safety of steroid‐eluting stent implantation on the surgical outcomes of patients with ECRSwNP. Ninety‐five patients completed the trial. At postoperative weeks 4, 8, and 12, the Lund‐Kennedy scores were significantly lower on the treatment side than on the control side (all p < 0.01). Steroid‐eluting stents reduce postoperative sinus mucosal oedema, and eosinophilic inflammation, with persistent effects after stent disintegration, and are a good supplementary postsurgical treatment in patients with ECRSwNP.
