Abstract

Purpose: A fresh-frozen human cadaveric feasibility study to investigate the feasibility of probing and stenting the nasolacrimal ducts (NLDs) of human cadavers with a novel flexible bicanalicular nasolacrimal stent.

Methods: A custom-designed bicanalicular nasolacrimal stent was made by connecting a 250 mm long, 0.9 mm diameter silicone tube to a 200 mm long stainless-steel, snake-chain probe at each end. The punctum was dilated, and the snake-chain stent fed into the nasolacrimal drainage system. The emergence of the stents from the terminal end of the NLD and retrieval with a ball probe was conducted under endoscopic guidance.

Results: Bicanalicular nasolacrimal stenting with intranasal retrieval under endoscopic guidance was successfully achieved in six NLDs of three adult cadaveric nasolacrimal drainage systems.

Conclusion: Despite being soft and flexible, the snake-chain silicon stent passes smoothly and freely through cadaveric human NLD and is easily retrieved from the nasal cavity. This novel NLD stent design may make stenting of the NLD easier and less traumatic.

用于鼻泪管插管的新型蛇链金属探针硅插管装置：尸体可行性研究。

目的：一项新鲜冷冻人体尸体可行性研究，旨在探讨使用新型柔性双腔鼻泪管支架对人体尸体的鼻泪管（NLD）进行探查和支架植入的可行性：方法：通过将一根长 250 毫米、直径 0.9 毫米的硅胶管与一根长 200 毫米的不锈钢蛇链探针两端连接起来，制作了一个定制的双腔鼻泪管支架。扩张穿刺孔后，蛇链支架进入鼻泪管引流系统。在内窥镜引导下，支架从鼻泪管末端伸出，并用球形探针取出：结果：在内窥镜引导下，在三个成人尸体鼻泪管引流系统的六个鼻泪管中成功实现了双腔鼻泪管支架植入和鼻内取出：结论：尽管蛇链硅支架柔软而有弹性，但它能顺利而自由地通过人体尸体的 NLD，并很容易从鼻腔内取出。这种新颖的鼻泪管支架设计可使鼻泪管支架置入手术更容易，创伤更小。
