Abstract
- This study is a clinical observation of the nasolacrimal duct stent intubation when obstruction of the nasolacrimal system is present. Ten patients with this reported condition participated in the study from September 1993 to July 1994. A polyurethane stent of 3.5cm in length, 5 Fr in outer diameter and 4 Fr in inner diameter was introduced in a retrograde direction. Surgical Results indicated that no major complications occurred in 9 out of the 10 cases longer than 3 months follow up. Pseudolumen was found in only one of the cases. In view of these results. We would like to suggest that the placement of polyurethane nasolacrimal stents may be a simple, safe, effective method of nonsurgical treatment of obstruction of the nasolacrimal system.
