目的 评估复发性鼻窦炎（RRS）患者行修正性内镜鼻窦手术（ESS）术中植入全降解鼻窦药 物支架（SES）对术区创面恢复的短期疗效。方法 选择由同一术者完成手术的复发性鼻窦炎患者，自身 对照方法在 ESS 术中随机分为支架侧（支架组）和对照侧（对照组）。术后 30、90 d，由独立评估小组根 据内镜检查结果评估支架侧和对照侧术区恢复情况，进行内镜评分和确定是否需要进行术后干预（手 术和口服激素干预）。结果 共计纳入的 30 例复发性鼻窦炎患者，术后 30 d，支架组相比对照组术后需 要干预的比例降低了50%（χ2 = 5.514，P = 0.007 0），其中手术干预下降50%（χ2 = 4.921，P = 0.043 9），口服激素 干预下降了50%（χ2 = 5.292，P = 0.022 7），额窦口通畅度提高60%（χ2 = 5.343，P = 0.034）；术后90 d，支架组 相比对照组术后需要干预的比例下降 50%（χ2 = 5.414，P = 0.024 5），其中手术干预下降 42.8%（χ2 = 4.887， P = 0.033 9），口服激素干预下降了 66.7%（χ2 = 5.492，P = 0.042 7），额窦口通畅度提高 44.4%（χ2 = 4.343， P = 0.044），炎症评分（VAS）差异有统计学意义（χ2 = 5.242，P = 0.035）。结论 RRS 术中置入 SES 提高 了额窦术后的通畅性，降低了 ESS 术后再干预的可能和术后的炎性反应，SES 治疗复发性鼻窦炎 的短期效果有效。

Objective Evaluation of the short term efficacy of fully degraded sinus drug ⁃stents（SES） implanted during modified endoscopic sinus surgery （ESS）in patients with Recurrent Rhinosinusitis （RRS）. Methods Patients with recurrent sinusitis who were operated by the same surgeon were selected and randomly divided into stent side and control side after ESS by self⁃control method. At 30 and 90 days after surgery ，an independent evaluation team evaluated the recovery of the stent and control sites based on the endoscopic findings， performed endoscopic scores（VAS），and determined the need for postoperative intervention（surgery and oral hormone intervention）. Results A total of 30 patients with recurrent sinusitis were included in this study. At 30 days after surgery，the proportion of patients requiring postoperative intervention in the stent group decreased by 50% compared with the control group（χ2 = 5.514，P = 0.007 0），including 50% for surgical intervention（χ2 = 4.921， P = 0.043 9）and 50% for oral hormone intervention（χ2 = 5.292，P = 0.022 7）. The patency of frontal sinus was increased by 60%（χ2 = 5.343，P = 0.034）. At 90 days post⁃ESS，the proportion of postoperative intervention in the stent group decreased by 50% compared with the control group（χ2 = 5.414，P = 0.024 5），among which，surgical intervention decreased by 42.8%（χ2 = 4.887，P = 0.033 9），and oral hormone intervention decreased by66.7% （χ2 = 5.492，P = 0.042 7）. The patency of frontal sinus opening was increased by 44.4%（χ2 = 4.343，P = 0.044）， and the inflammation score（VAS）was significantly different（χ2 = 5.242，P = 0.035）. Conclusion The implan⁃ tation of SES in RRS improves the postoperative patency of frontal sinus，reduces the possibility of reintervention after ESS and postoperative inflammatory response，and the short⁃term effect of SES in the treatment of recurrent sinusitis is effective.
