先天性泪囊突出的研究进展

The research progress of congenital dacryocystocele

先天性泪囊突出是由于鼻泪管远端（Hasner瓣膜）和近端（Rosenmuller瓣膜）的同时堵塞引起泪囊继发性扩张而形成，典型临床表现为泪囊区皮下青紫色肿物，其与儿童常见先天性泪囊炎有很大区别。此病有自愈倾向，保守治疗有一定疗效，但易引发严重的感染、呼吸窘迫等危及生命的并发症。近来研究倾向于先行保守治疗，无效后再行手术治疗。

Congenital dacryocystocele is formed when the nasolacrimal duct is obstructed at both the proximal and terminal ends, i.e. at the valve of Rosenmuller and the valve of Hasner, which results in the secondary dilatation of lacrimal sac. The main clinical manifestation is a bluish mass at lacrimal sac area. It is different from the common congentital dacryocystitis during childhood. There is self-healing tendency and effectiveness of conservative treatment for congenital dacyocystocele, but it is subject to the complication of the serious infection and life-threatening respiratory distress. Recent research is inclined to conservative treatment initially, then surgery if conservative treatment failed.
