AIM:To identify the risk factors of epiphora in patients with anatomical patency after surgical repair of canalicular ***:This retrospective case series included 178 cases of canalicular laceration repair from 2005 to *** data collected from each patient included age,sex,type of injury,distance from the distal lacerated end of the canaliculus to the punctum,the severity score for the structural abnormity of the medial canthus,the duration of stent placement,and the timing of *** risk factors for epiphora were evaluated using Logistic regression ***:Among the 178 cases,45(25.3%)with lacrimal patency after irrigation had symptomatic epiphora at the final ***'sex,age,type of injury,duration of stent placement,timing of surgery,and concurrent trauma were not found to be significantly associated with symptomatic epiphora after surgical repair of the lacerated canaliculus(P>0.05).A distance of more than 5 mm from the distal cut end to the punctum was closely and significantly associated with symptomatic epiphora after surgical repair of the lacerated canaliculus(P<0.01).Symptomatic epiphora was significantly more frequent in patients with higher severity scores for structural abnormities of the medial canthus(P<0.01).CONCLUSION:Our results indicate that the risk factors for postoperative symptomatic epiphora include a further distance between the distal cut end and the lacrimal punctum and a higher severity score for structural abnormities of the medial *** findings could be used to prognosticate postoperative symptomatic epiphora.

Objective： To study the therapeutic efficiency and effecacy of laser-directing approach on searching for the nasal broken end of lacerated lacrimal canaliculus in anastomosis for canalicular laceration. Methods ： Forty-nine patients （ 49 eyes ） suffering from traumatic inferior canalicular laceration were divided into control group and laser-directing group. The distance between the lacrimal puncture and the nasal broken end of lacerated lacrimal canaliculus was more than 6 ram. During the course of management of eyelid trauma, the patients were treated by canalicular anastomosis operation with traditional method and laser-directing method in searching for the nasal broken end of lacerated lacrimal canaliculus respectively. The silicone tube of 1 mm diameter was intubated in the lacrimal passage as a stent for 4 to 6 months. Results： In the laser-directing group, the mean time in searching for the nasal broken end of lacerated lacrimal canaliculus was （5.75 ± 1.49） minutes and the mean time of operation was （49.21 ±3.37） minutes; both were significantly shorter than that of the control group （P 〈 0.01 ）. The cure rate of the laser-directing group was 96.55 %, higher than that of the control group but without statistical significance （ P 〉 0.05 ）. Conclusions： The laser-directing method is much quicker and more convenient to searching for the nasal broken end of the lacerated lacrimal canaliculus than the traditional approach, and patients suffer less pain and damaging in canalicular anastomosis operation.
