Abstract:

Objective To investigate the curative effects of lacrimal duct drill combined with lacrimal duct intubation on the chronic dacryocystitis. Design Retrospective case series. Participants 98 chronic dacryocystitis cases in Affiliated Hospital of Hainan Medical University from June 2015 to February 2017. Methods 98 cases were divided into observation group and control group with 49 cases in each group accorded to the random draw envelope principle. The control group was given lacrimal duct drill, the observation group was treated with lacrimal duct drill combined with the lacrimal duct intubation. Curative effect, ocular surface changes score and complications were recorded and compared between the two groups. The follow-up duration was 3 months. Main Outcome Measures curative effect, ocular surface changes score and complications. Results After 3 months, the cure rate of the observation group and the control group was 98% and 85.7%, respectively (P=0.008). The ocular surface change scores at postoperative 3 months in the observation group and the control group was 18.00±4.22 and 23.88±3.91 respectively, which were significantly lower than that of preoperation(P=0.000, 0.013), and the score in the observation group was significantly lower than that in the control group (P=0.018). The complication (lacrimal laceration, granulation formation, nasal bleeding) rate was 4.1% in the observation group, 18.4% in the control group(P=0.010). Conclusion Combined with lacrimal intubation, lacrimal duct drill can improve the cure rate and reduce the incidence of postoperative complications for the chronic dacryocystitis patients, which can also improve ocular symptoms.
