Objective To evaluate the intraoperative and postoperative effects of new type and modified probe in fractured lacrimal duct anastomosis.Methods Forty-nine patients with lower canalicular laceration were included in this study.The operation comparison was performed between the modified probe in a manner of synchronous intubation and the traditional pigtail probe.The differences of intraoperative effects were observed,and the clinical effects were assessed at postoperative 3,12 months.Results The average intubation time was(10.05±1.51)min in the observation group and(32.30±4.70)min in the control group,the difference was statistically significant(t=23.63,P0.01),the average whole operation time was(32.91±3.98)min in the Observation group and(53.74±5.48)min in the control group,the difference was statistically significant(t=15.71,P0.01).The rates of anatomic and functional success were 100.0%(22cases)and 90.9%(20cases)in the observation group,which were significantly higher than 70.4%(19cased)and 59.3%(16cases)in the control group,the difference was statistically significant(χ2=5.77,P0.05;χ2=6.23,P0.05).The punctal dilator was used by 18 times in the observation group and by 13 times in the control group,the difference was statistically significant(χ2=5.91,P0.05),nevertheless no punctal incision was used.The rates of anatomic and functional success detected at 3postoperative months,intraoperative once success and final success rates and postoperative complications showed no statistically significant differences(P0.05).Conclusion The modified probe provides a synchronous intubation new type operation mode,which simplifies the operation procedure,increases the operative success rate and partially reduces the occurrence of postoperative complications.
