睑外伤常致下泪小管断裂,我们自1991年7月至1993年11月应用缝针将丝线引入上下泪小管并留置2～3月.共治疗19例,取得满意效果.随访观察17例,时间为3～20月.冲洗泪道通畅,无溢泪症状15例,通而不畅,见风有轻度溢泪者2例.手术方法患眼表面麻醉,切口周围浸润麻醉.扩张上泪点,由此穿入1/2圆6×14弯成弓形圆针之尾端(带针孔端),持针器夹持圆针之尖端,顺上泪小管至上下泪小管交接处转入下泪小管(注意进针时无明显阻力),由下泪小管鼻侧断端穿出后,针孔穿4号丝线退针,将线置留于泪小管内.扩张下泪点,由此穿入圆针尾端,经下泪小管颞侧断端穿出,针孔穿入留于鼻侧断端的4号丝线,退针,将4号丝线自下泪点拉出,拉紧此线,泪小管断端对合并缝合2针,再缝合皮肤伤口,留置线固定于额部.术后每日换药2次,活动留置线1次,7天拆除皮肤伤口缝线,2～3月后拆除泪小管内留置线,冲洗泪道,通畅为痊愈.
Eyelid injury often caused by tear canaliculus rupture, we from July 1991 to November 1993 application of silk needle into the upper and lower canaliculi and indwelling 2 to 3 months, a total of 19 cases were treated with satisfactory results. Follow-up observation of 17 cases, Time for 3 to 20 months .Purification lacrimal duct patency, no symptoms of spilled tears in 15 cases, but not smooth, see the wind with mild spilled in 2 cases .Surgery on the surface of the eye anesthesia, anesthesia around the incision infiltration. Point, thus penetrating 1/2 round 6 × 14 curved into the end of an arcuate round needle (with pinhole end), needle holder clamp the tip of the round needle, along the lacrimal duct to the tear canal junction into Under the lacrimal canaliculus (pay attention to no obvious resistance when entering the needle), punctate the nasal lacrimal duct and punctate the end of the piercing, the needle piercing on the 4th silk retracting needle, place the line in the lacrimal duct and dilate the punctum, thus Penetrate the end of the round needle, pierced through the punctate end of the temporal canal of the lacrimal canal, penetrate the No. 4 silk thread left in the nasal stump, withdraw the needle, pull out the No. 4 thread from the tear point, tighten this Line, the end of the canaliculus stitches combined stitching 2 needles, and then sutured the skin wounds, indwelling line fixed in the forehead .One day dressing 2 times a day, activity indwelling line 1, 7 days to remove the skin wound suture, 2 to 3 Month after removal of lacrimal duct stay line, Wash lacrimal duct patency was recovered.
