目的：探究高位泪囊鼻腔吻合术（DCR）联合RS泪道再通管治疗慢性泪囊炎（CD）的临床效果。方法：选择110例于2021年1月至2023年1月至本院进行CD治疗的患者，根据治疗方法分为对照组（高位DCR+纳吸棉）、观察组（高位DCR+RS泪道再通管）各55例，比较两组患者的临床相关指标、临床疗效、生活质量和并发症发生情况。结果：观察组的解剖成功率（96.36%）和功能成功率（92.73%）均明显高于对照组（83.64%，76.36%）（P＜0.05）；观察组总有效率显著高于观察组（观察组98.18%vs对照组78.18%）（P＜0.05）；治疗前，两组简明健康状况调查表（SF-36）经比较无明显差异（P＜0.05），术后6个月，两组评分均升高，且观察组高于对照组（P＜0.05）；两组总并发症比较无统计学意义（观察组10.91%；对照组20.00%）（P＞0.05）。结论：高位DCR联合RS泪道再通管能够有效改善CD患者临床症状，提高生活质量，增强临床疗效，且不增加并发症发生率。

Objective: To explore the clinical effect of high dacryocystonasal anastomosis (DCR) combined with RS lacrimal duct recanalization in the treatment of chronic dacryocystitis (CD). Methods: A total of 110 patients who came to our hospital for CD treatment from January 2021 to January 2023 were randomly divided into control group (high DCR+ absorption-cotton) and observation group (high DCR+RS lacrimal duct recanalization) with 55 cases in each group by random number table method. The clinical indicators, clinical efficacy, quality of life and complications of the two groups were compared. Results: The anatomical success rate (96.36%) and functional success rate (92.73%) of the observation group were significantly higher than those of the control group (83.64%, 76.36%) (P<0.05).; The total effective rate of observation group was significantly higher than that of observation group (observation group 98.18% vs control group 78.18%) (P<0.05); Before treatment, there was no significant difference between the two groups in the Concise Health Status Questionnaire (SF-36) (P<0.05). 6 months after surgery, the scores of both groups were increased, and the observation group was higher than the control group (P<0.05).; There was no statistical significance in the total complications between the two groups (observation group 10.91%; Control group 20.00%) (P>0.05) Conclusion: High DCR combined with RS lacrimal duct recanalization can effectively improve the clinical symptoms of CD patients, improve the quality of life, enhance clinical efficacy, and do not increase the incidence of complications
