目的：探讨膨胀海绵与透明质酸钠在鼻内窥镜下泪囊鼻腔吻合术中的应用。

方法：回顾性研究。对2016-01-01/2018-12-31我院行鼻内窥镜下泪囊鼻腔吻合术患者进行随访观察，A组153例184眼术中应用膨胀海绵与透明质酸钠，B组138例160眼术中应用泪道支架，对两组患者术后疗效进行比较。

结果：术后6mo的泪道通畅和流泪改善情况，A组总有效率为90.2%(166眼)，B组为82.5%(132眼)，有统计学差异(P<0.05)。A组重度并发症者6眼(3.3%)，B组重度并发症者20眼(12.5%)，有统计学差异(P<0.05)。

结论：鼻内窥镜下泪囊鼻腔吻合术中应用膨胀海绵与透明质酸钠较应用泪道支架疗效好，可减少并发症。

METHODS: Through the follow-up observations of the 184 eyes(153 cases)that underwent dacryocystorhinostomy under nasal endoscope in our hospital in the past 2a(2016-2018)(group A: intraoperative application of expanded sponge and sodium hyaluronate), and the comparison in efficacy of 160 eyes(138 cases)that underwent dacryocystorhinostomy under nasal endoscope in our hospital in the past 2a(group B: intraoperative lacrimal duct stent).

RESULTS:The statistics analyzed from the patency of lacrimal passage and the improvements of the lacrimation six months after surgery are as follows: the total effective rate was 90.2% in group A, which amounts to 166 eyes; and 82.5% in group B, which amounts to 132 eyes. The difference between the two was statistically significant(P<0.05). Severe complications in group A were 6 eyes, 3.3%; severe complications in group B were 20 eyes, 12.5%, and the difference was statistically significant(P<0.05).

CONCLUSION: The application of expanded sponge and sodium hyaluronate in the application of intranasal dacryocystorhinostomy can significantly improve the surgical effect and reduce complications.
