Epiphora in infancy is most commonly the result of failure of canalisation of the nasolacrimal duct and most cases resolve spontaneously within 12 months. Lacrimal probing is the standard operative treatment when conservative expectant management fails. While this carries a high success rate, it does not reliably localise the site of obstruction, can create a false passage and may induce traumatic stenosis in the lacrimal passages. Nasendoscopy in conjunction with the lacrimal probing overcomes these problems as the procedure is performed under direct vision. The precise site of opening of the nasolacrimal duct is ascertained, the nature of obstruction established and the risks of false passage creation minimised. We report this technique of endoscopic assessment of lacrimal probing, and the outcome results of twenty such procedures performed on thirteen children.
婴儿溢泪最常见的原因是鼻泪管管道化失败，大多数病例在12个月内可自行缓解。当保守的观察治疗失败时，泪道探通术是标准的手术治疗方法。虽然该方法成功率较高，但不能可靠地定位阻塞部位，可能形成假道，并可能导致泪道创伤性狭窄。鼻内镜联合泪道探通术可克服这些问题，因为该手术是在直视下进行的。可确定鼻泪管开口的精确位置，明确阻塞的性质，并将形成假道的风险降至最低。我们报告这种内镜评估泪道探通术的技术，以及对13名儿童进行的20例此类手术的结果。
