There are several well established methods to correct congenital and acquired lacrimal canalicular stenosis. The primary goal of all these surgical methods is the reopening and recanalization of a functional lacrimal pathway. Intubation by bicanalicular or monocanalicular silicone tubes has been established as a means of enhancing the redevelopment of a smooth epithelial surface and keeping the recanalized tear ducts continuously open. The use after endocanalicular surgery is mostly undisputed and unequivocally advocated after trauma but the use after either endonasal or transcutaneous dacryocystorhinostomy is still controversial as there is no clear evidence that it produces superior results. There are several systems available to place monocanalicular or bicanalicular silicone tubes. The decision to place an intubation depends mainly on the level and the type of stenosis.
有几种成熟的方法可用于矫正先天性和后天性泪小管狭窄。所有这些手术方法的主要目标都是重新开通并重建一条功能性泪道。通过双泪小管或单泪小管插入硅胶管已被确立为一种促进光滑上皮表面重新发育并保持再通的泪道持续开放的方法。泪小管手术后使用硅胶管大多并无争议，外伤后使用也明确受到提倡，但在内眦泪囊鼻腔吻合术或经皮泪囊鼻腔吻合术后使用仍存在争议，因为尚无明确证据表明其效果更佳。有多种系统可用于放置单泪小管或双泪小管硅胶管。是否进行插管主要取决于狭窄的程度和类型。
