目的：分析Lund-Mackay评分预测慢性泪囊炎合并慢性鼻窦炎同期手术疗效的作用。

方法：将我院2016-05/2019-03就诊的慢性泪囊炎合并慢性鼻窦炎的患者共92例92眼纳入前瞻性单盲研究，根据Lund-Mackay评分将患者病情分为轻(22例)、中(34例)、重(36例)三组，每组随机分为同期手术组和分期手术组。比较同期手术与分期手术的手术疗效和并发症情况。

结果：轻度和中度慢性泪囊炎合并慢性鼻窦炎患者，同期和分期手术手术有效率、并发症均无差异(P>0.05)； 重度慢性泪囊炎合并慢性鼻窦炎患者，分期手术有效率高于同期手术(94% vs 61%，P<0.05)，并发症发生率低于同期手术(P<0.05)。

结论：根据Lund-Mackay评分，轻度和中度慢性泪囊炎合并慢性鼻窦炎患者建议同期手术，重度患者建议分期手术。

METHODS: Totally 92 cases(92 eyes)of chronic sinusitis with chronic dacryocystitis in our hospital from May 2016 to March 2019 were included in the prospective, single-blind study. According to Lund-Mackay score, the patients were divided into three groups: mild(22 cases), moderate(34 cases)and serious(36 cases). Each group was randomly divided into simultaneous operation group and phased operation group. We compared the operative effect and complications of simultaneous and phased operations.

RESULTS: In patients with mild and moderate chronic sinusitis combined with chronic dacryocystitis, there was no statistical difference in the efficiency and complications between simultaneous and phased operations(P>0.05). In patients with severe chronic sinusitis combined with chronic dacryocystitis, the efficiency of phased operations was higher than that of the simultaneous surgery(94% vs 61%, P<0.05), and the complications were lower than that of the simultaneous surgery(P<0.05).

CONCLUSION: According to Lund-Mackay score, patients with mild to moderate chronic sinusitis and chronic dacryocystitis are advised to undergo simultaneous surgery, while patients with severe rhinosinusitis are advised to undergo phased surgery.
