泪小管断裂的诊治进展

Progress in diagnosis and treatment of lacrimal canalicular laceration

泪小管断裂是泪道系统最常见的创伤类型,通常伤情复杂,治疗较为困难.泪小管断裂需要精细对位吻合,否则将导致永久性溢泪,且会出现内眦畸形、睑外翻等并发症,给患者的身心带来极大的影响.近年来,关于泪小管断裂诊治的研究及临床治疗取得了较大进展.本文针对临床医生较为关注的病因、手术指征、修复时机、断端定位、置管方法及取管时间等方面做简要综述.

Lacrimal canalicular laceration is the most common wound type in lacrimal duct system,which is complicated and the treatment is difficult.Lacrimal canalicular laceration requires precise contrapuntal anastomosis,otherwise permanent epiphora and complications such as inner canthus deformity and eyelid ectropion will occur,which will bring great physical and mental effects to patients.In recent years,great progress has been made in the research and clinical treatment of lacrimal canalicular laceration.This paper briefly reviewed the etiology,surgical indications,repair time,localization of broken ends,catheterization methods and time of catheter removal.
