婴幼儿先天性泪囊炎鼻泪管探通术操作体会

目的：探讨先天性泪囊炎鼻泪管探通术的阻塞性质与疗效预测的关系及其并发症的分析。方法：对474例3-47个月（平均25个月）婴幼儿先天性泪囊炎患儿作鼻泪管探通术的治疗进行回顾性分析。结果：在474例9494只眼）患儿中，存在膜性阻力的有360眼，治愈356眼，占98.89%；不存在阻力有122眼，治愈107眼，占85.25%；遇到狭窄的有12眼，治愈8眼，占66.67%；发生泪小管撕裂有3眼，皮下水肿1眼，未发生出血，感染，眼球损伤和窒息等并发症。结论：发现鼻泪管探通术的阻塞性质与疗效有密切关系。另外，婴幼儿鼻泪管探通术要求技术熟练，动作轻巧和固定良好，才能把并发症的发生率降到最低。

Probing of Lacrimal Passage on Congenital Dacryocystitis

Purpose: To investigate the effects of probing of lacrimal passage on congenitaldacryocystitis.Methods: 474 consecutive infants with congenital dacryocystitis were treated withprobing of lacrimal passage. The data were retrospectively analyzed.Results: In 474 eyes, there were 360 and 122 eyes with or without membranous blockrespectively, and 356 (98. 89% ) and 107 eyes(85. 25% ) with or without membranousresistance were respectively cured with probing of lacrimal passage; there were 12 eyeswith stenosis and 8 eyes (66. 67% ) were cured. In operation, 1 and 3 eyes wererespectively suffered from subcutaneous edema and laceration of canaliculus, but therewas no baby suffered from infection or asphyxia.Conclusions: The effects of probing of lacrimal passage were related to the causes ofobstruction of lacrimal passage, and it is very important to scrupulously feel in probinglacrimal passage.
