Probing of the nasolacrimal duct is a common procedure in children with congenital stenosis. Although simple probing of the nasolacrimal duct is successful in a majority of patients, a number of failures occur. In those temporary intubation of the nasolacrimal duct with a silicone drain may solve the problem. We performed silicone intubation in 11 infants under nasal endoscopic control. By this improved visualization of the inferior meatus, the procedure was facilitated. In four children the probe was unable to pierce the nasal mucosa and stayed in the submucosal space. An incision of the nasal mucosa was needed before the probe could be passed into the nasal lumen. We believe that this situation, inability to pierce the nasal mucosa, may explain a number of failures of simple probing. It is therefore advisable, especially if initial probing has failed, to repeat the procedure under endoscopic control.
鼻泪管探查术是先天性狭窄患儿的常见手术。尽管大多数患者单纯鼻泪管探查术可成功，但仍有一些失败病例。对于这些患者，使用硅胶引流管进行鼻泪管临时插管可能解决问题。我们在鼻内镜控制下对11例婴儿进行了硅胶插管。通过改善下鼻道的可视化，手术得以顺利进行。在4名儿童中，探针无法穿透鼻黏膜而停留在黏膜下间隙。在探针能够进入鼻内管腔之前，需要切开鼻黏膜。我们认为，这种无法穿透鼻黏膜的情况可能解释了一些单纯探查失败的原因。因此，尤其是在初次探查失败的情况下，建议在内镜控制下重复该手术。
