Abstract
The authors report the case of a 7-year old child with failed probing with stent intubation, who was found to have an unusual curvature of the nasolacrimal duct on the symptomatic side. CT imaging revealed a permanent maxillary canine tooth adjacent to the duct. It appeared that the relationship of the tooth bud to the curved nasolacrimal duct was most likely responsible for the symptoms of epiphora on this anomalous side.
摘要
作者报告了一例 7 岁儿童经支架插管探查失败的病例，该儿童在症状侧发现鼻泪管异常弯曲。CT 成像显示有一颗永久性上颌尖牙紧邻该管道。似乎是牙胚与弯曲的鼻泪管的关系导致了这一侧异常溢泪的症状。
