硅胶管环形植入治疗泪小管断裂的临床应用【摘要】目的:探讨硅胶管环形植入在泪小管断裂吻合术中的应用,并评价其临床价值。方法:对33例(33眼)外伤性泪小管断裂患者,在手术显微镜下寻找鼻侧断端,利用自制探针引导硅胶管呈环形骑跨于上下泪小管,吻合汨小管周围组织2~3针,使汨道恢复正常解剖结构。硅胶管留置3~6个月。结果:拔管后随访6~12个月。33例患者全部成功置管吻合,其中治愈32例(96.97%),好转1例(3.03%)o结论:硅胶管环形植入治疗泪小管断裂,安全有效,成木低,成功率高,可为其他泪道置管术提供有益的借鉴与参考。【关键词】硅胶管;环形植入;泪小管断裂中图分类号R777.2文献标识码B文章编号1674-6805(2015)33-0022-03TheClinicalApplicationofAnnularSiliconeTubeInsertionintheTreatinentofCanaliculiLaceration/CAILi-mei,CAIFu~xu,CHENMin,etal.//ChineseandForeignMedicalResearch,2015,13(33):22-24[Abstract】Objective:Toinvestigatetheapplicationofannularsiliconetubeinsertionontherepairofcanaliculilaceration,andestimateitsclinicaleffect・Method:33patients(33eyes)oftraumaticcanaliculuslacerationwereselected,thenasalsideofdisruptedcanaliculilacrimalisundersurgerymicroscopewaslocatedandthesiliconetubeannularoverridingonthecanaliculilacrimalisbyself-madeprobewasused,andsurroundingtissuesofthelacrimalcanaliculusfor2-3needleswasanastomosed,thelacrimalpassagewasreformeditsnormalanatomicstructure.Allthesiliconetubeswereindwelledfor3-6months.Result:Allthepatientswerefollowedup6~12monthsafterthetubeswerepulledout.The33cases(33eyes)ofcanalicularlacerationpatientswereal1successfullyanastomosedbysi1iconetubeinsertion.Ofwhich,32caseswerecured(96.97%),and1casewasimproved(3.03%)•Conclusion:Itisansafeandeffectivemethodoflacrimalcanaliculusanastomosisoperation,withlowcostandhighrateofsuccess,andwillprovidehelpfulreferencetootherlacrimalpassageintubation.[Keywords】Siliconetube;Annularinsertion;CanalicularlacerationFirst-author'saddress:AffiliatedHospitalofPutianUniversily,Putian351100,Chinadoi:10.14033/j.cnki.cfmr.2015.33.010泪小管断裂在眼外伤中是一种常见病,如未及时修补,瘢痕愈合、泪道阻塞可导致终身溢汨,严重影响了患者口常工作与生活。显然,及时正确处理很有必要,冃前泪小管断裂吻合术是行之有效的治疗方法,而所植入支撑物的舒适度与留置时间的长短常常决定了手术的成败[1]。近年来,笔者所在科采用的硅胶管环形植入在外伤性泪小管断裂吻合术中取得了良好成效,现做如下报告。1资料与方法1.1一般资料2011年1月-2015年1月笔者所在医院共收治33例(33眼)泪小管断裂患者,其中上泪小管断裂3例,下泪小管断裂30例,男25例,女8例,年龄16〜65岁,平均37岁。致伤原因有拳击伤、车祸伤、锐器伤、摔伤等,接受手术时间均在受伤后12h之内,且为新鲜未经清创缝合等处理。1.2器械设备泪小点扩张器、泪道探针、医用硅胶管(外径l・0mm、内径约0.4mm的空心硅胶软管)、引导探针(实心,长约12cm.管径约0.5mm,两端呈泪滴状隆起)及与之相匹配的环状拉钩。1.3手术方法将浸有0.1%肾上腺素与2%利多卡因混合液的棉签插入下鼻道,收缩鼻腔黏膜。清洗伤口,常规消毒铺巾,取2%利多卡因与0.75%布比卡因等比例混合,行滑车及眶下神经阻滞麻醉。手术显微镜直视下寻找泪小管的两游离断端。颖侧断端易于寻找,自泪小点以泪道探针探查即可找到,关键是鼻侧断端的寻找:根据与泪小点距离越远泪小管距睑缘走行越深,来推断泪小管鼻侧断端大概位置[2],显微镜下可见泪小管鼻侧断端呈乳白色“小喇叭”状膜性开口,并进行泪道冲洗证实通畅[3]。以较常见的下泪小管断裂为例,找到泪小管鼻侧断端后,将引导探针自下泪小管鼻侧断端探入,经泪总管、泪囊、鼻泪管顺行至下鼻道,再由环状拉钩将探针牵引至鼻腔外,末端套上硅胶管,用6-0缝线打结扎紧,涂少许红霉索眼膏润滑,向上...
