目的：分析鼻内镜下泪囊鼻腔吻合术手术疗效的影响因素。方法：纳入2021年1月—2023年7月在成都中医药大学附属医院眼科行鼻内镜下泪囊鼻腔吻合术(endoscopic dacryocystorhinostomy, En-DCR)治疗的单眼慢性泪囊炎患者90例(90只眼)。所有患者均进行泪道CT造影检查及鼻内镜下泪囊鼻腔吻合术，术后随访6个月，评估手术疗效，分析手术疗效的影响因素。结果：本研究显示，慢性泪囊炎患者中女性占比为90%，平均年龄为(49.97±13.10)岁。单因素分析结果显示，术中是否置入引流管、下鼻甲肥厚与EnDCR手术疗效有关(P < 0.05)。Logistic多因素回归分析结果显示，下鼻甲肥厚为En-DCR手术疗效的危险因素(P < 0.05)。结论：慢性泪囊炎多发生于中老年女性。下鼻甲肥厚为En-DCR手术疗效的危险因素。

Objective: To analyze the influencing factors for effect of endoscopic dacryocystorhinostomy. Methods: A total of 90 patients (90 eyes) diagnosed with unilateral chronic dacryocystitis undergoing endoscopic dacryocystorhinostomy in the Department of ophthalmology, Hospital of Chengdu University of Traditional Chinese Medicine from January 2021 to July 2023 were included. All patients underwent lacrimal duct CT imaging and endoscopic dacryocystorhinostomy, and were followed up for 6 months to evaluate the efficacy of surgery. Results: This study showed that 90% of patients with chronic dacryocystitis were female, and the average age of patients was (49.97±13.096) years. The results of univariate analysis showed that there was a correlation between intraoperative drainage tube placement and inferior turbinate hypertrophy and the efficacy of En-DCR (P < 0.05). The results of Logistic regression analysis showed that inferior turbinate hypertrophy was a risk factor for the efficacy of En-DCR (P < 0.05). Conclusions: Dacryocystitis mostly occurs in middle-aged and elderly women. Inferior turbinate hypertrophy are the influencing factors of surgical effect. Chronic dacryocystitis mostly occurs in middle-aged and elderly women. Inferior turbinate hypertrophy is a risk factor affecting the curative effect of En-DCR surgery.
