ABSTRACT
@#AIM: To investigate the application of expanded sponge and sodium hyaluronate in dacryocystorhinostomy under nasal endoscope.<p>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).<p>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(<i>P</i><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(<i>P</i><0.05).<p>CONCLUSION: The application of expanded sponge and sodium hyaluronate in the application of intranasal dacryocystorhinostomy can significantly improve the surgical effect and reduce complications.
