The value of Lund-Mackay score in predicting the effect of simultaneous surgery of chronic dacryocystitis with chronic sinusitis

AIM: To explore the value of Lund-Mackay score in the surgical treatment of chronic dacryocystitis with chronic sinusitis.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
