摘要
目的介绍一种硅胶管双路置入法在下泪小管断裂吻合术中的应用。方法选取外径1mm、内径0．6-0．7mm、长12cm的医用细硅胶管自制∩形管。另取直径0．14mm长20cm的鱼线两端打结做成鱼线环。硅胶管对折套在鱼线环上，双管拉入再抽成单管，经三次：（1）下鼻道→鼻泪管→泪囊→泪小管鼻侧断端，（2）泪小管鼻侧断端→泪小管颞侧断端→下泪小点，（3）下泪小点→上泪小点→泪囊→鼻泪管→下鼻道，硅胶管呈∩形将断裂泪小管串联吻合，置入硅胶管后泪小管断端周围可不用缝线缝合。将其应用于外伤性泪小管断裂21例（21只眼）。结果术后3月拔管，随访半年至1年，治愈16例占76．19％；好转5例占23．81％。结论本文的方法取材容易，材料便宜，硅胶管固定牢固，泪小管断端对合牢靠，不影响美观，并发症少，疗效好，值得推广应用。
Objective To introduce the method of silicone tube double-passage intubation in anastomosis for inferior lacrimal canalicular laceration. Methods A thin silicone medical tube （outside diameter of 1mm, inner diameter 0.6-0.7mm, length 12cm） was made into a N-shaped tube and a fishing line （diameter 0.14mm, length 20cm） was selected, both ends tied into a fishing knot. The silicone tube was folded and set in ring of the fishing line. Two-tube were pulled to a single tube, going three times through： （1） the inferior meatus → nasal lacrimal duct →lacrimal sac →canalicular nasal side cut ends, （2） the canalicular nasal side cut ends →canalicular temporal side cut ends →inferor lacrimal point, （3） the inferior lacrimal puncta →the superior lacrimal puncta →1ac- rimal sac→ inferior meatus. The N-shaped silicone tube showed a series coincides of fracture canalicular. After placing the silicone tube, the canalicular cut ends around were not sutured. Twenty-one cases （21 eyes） of traumatic canalicular laceration were treated by silicone tube double-passage intubation. Results After 3 months the silicone tubes were pulled. Following-up six months to a year, 16 cases （76.19% of the total） were cured and 5 cases （23.81%） were improved. Conclusions With the silicon tube easy to access, cheap and firmly fixed, the canalicular ends coherent firmly, and the appearance unaffected, the Silicon tube double-passage intubation is satisfactory .and worthy of promotion and generalization.
