The efficacy of minimally invasive repair for laceration of inferior lacrimal canaliculus

Objective To evaluate the clinical efficacy of minimally invasive repair and anastomosis of inferior lacrimal canaliculus laceration. Methods The data of 83 eyes of 83 patients with inferior lacrimal canaliculus laceration in this hospital from Dec. 2015 to Apr. 2018 were retrospectively analyzed. The study included 29 cases in the observation group and 54 cases in the control group. All cases performed surgery under the operating microscope, and the broken end of the nasal side were directly probed along the wound edge during operation. The control group adopted the ordinary anastomosis method of dual anterograde intubation with silicone stent. The observation group adopted minimally invasive anastomosis method. The lacrimal duct stent was placed into the lacrimal duct to anastomose the inferior lacrimal canaliculus laceration. All cases were followed up for 6 months. Results The operation time of the observation group was significantly shorter than that of the control group, and the difference was statistically significant (P=0.000). There was no significant difference in the recovery rate between the two groups (P=0.807). The incidence rate of puncta slitting in the observation group were significantly lower than that in the control group (P=0.046). Conclusion The minimally invasive repair for inferior lacrimal canaliculus rupture does not cause secondary injury, and the efficacy is definite.
