To evaluate the value of silicone intubation and ring-fixed method in canalicular laceration. ●METHODS: A retrospective study of 36 cases with laceration of lacrimal canaliculus. For all the patients, microscope was used to find the broken ends of the lacrimal canaliculus, and then straight insertion was performed to the distant and near broken ends through the upper and lower lacrimal points, then passed the dacryocyst to insert nasolacrimal canal and ended up in inferior nasal meatus. Thus, clinical data about forming annular support to treat laceration of lacrimal canaliculus was presented here. ● RESULTS: All 36 patients with traumatic canalicular laceration were anastomosed successfully and all patients healed without infection. The surgery went well, intubation was smoothly, all patients were followed - up for another 6mo after the stent was removed. The accidental fall off of the stent was not observed during the follow - up. During the follow - up 10 - 18mo after extubation, when the stent was removed, 32 cases (88. 9%) recovered to normal lacrimal drainage function;4 cases ( 11. 1%) remained epiphora with obstructed lacrimal passage. All cases were no lower eyelid ectropion. ●CONCLUSlON: For the patients with inferior canalicular laceration, the silicone intubation and ring-fixed method is effective, low irritation and less complication.%目的：探讨环形双泪道硅胶引流管植入术在治疗泪小管断裂的应用价值。 方法：回顾性研究Ⅰ期泪小管断裂患者36例,全部患者在显微镜下寻找到泪小管两断端后经上、下泪点直接插入远、近两侧断端泪小管,再经泪囊插入鼻泪管至下鼻道,形成环形支撑治疗泪小管断裂的临床资料。 结果：患者36例术中全部成功吻合,无感染,术中插管顺利,留置6mo,观察10~18mo,留置的引流管无意外脱落。拔管后,32例(88.9%)治愈,无溢泪,泪道通畅,4例(11.1%)好转,轻度溢泪,泪道通而不畅,均无下睑外翻。 结论：利用环形双泪道硅胶引流管植入术治疗泪小管断裂具有治愈率高、刺激性小、并发症少等优点。
