We examined the location of the internal orifice of congenital lacrimal fistula using a dacryoendoscope in 5 patients. A suture inserted from the skin orifice and passing into the lacrimal drainage system through the fistula track was identified using a dacryoendoscope. Consequently, the suture passed into the lacrimal sac in all patients. Although the internal orifice had been reported to be predominantly located in the common canaliculus, the methods previously used for identification of the internal orifice were less accurate. The results in our study suggest a higher incidence of congenital lacrimal fistulae connected with the lacrimal sac.
我们使用泪道内镜检查了 5 例先天性泪瘘的内口位置。使用泪道内镜，从皮肤瘘口插入缝线，穿过瘘道进入泪道引流系统，可识别缝线进入泪囊的位置。因此，所有患者的缝线均进入泪囊。尽管内口主要位于共同管内，但以前用于识别内口的方法准确性较低。我们的研究结果表明，与泪囊相连的先天性泪瘘发生率更高。
