Summary
Polyurethane stent placement effectively treats nasolacrimal obstruction, offering a minimally invasive option. This technique demonstrated high patency rates and successful resolution of epiphora in most patients.
Area of Science:
- Ophthalmology
- Otorhinolaryngology
Background:
- Nasolacrimal obstruction causes significant discomfort and visual impairment.
- Traditional treatments like dacryocystorhinostomy can be invasive.
Purpose of the Study:
- To evaluate the initial outcomes of treating nasolacrimal obstruction using polyurethane stents.
- To assess the efficacy and safety of this novel stent placement technique.
Main Methods:
- 74 polyurethane stents were implanted in 64 patients with nasolacrimal obstruction under fluoroscopic guidance.
- Dacryocystography and CT scans confirmed stent placement and patency.
- Clinical follow-up occurred at regular intervals up to 6 months, with a mean follow-up of 15 months.
Main Results:
- Successful stent insertion and patency were achieved in 92.1% of patients.
- Epiphora was resolved in 82.8% of cases with patent stents.
- Stent permeability was maintained in 5 cases (7.8%) despite persistent epiphora.
Conclusions:
- Polyurethane stent placement is a safe and effective non-invasive treatment for nasolacrimal obstruction.
- This technique offers improved results and patient tolerance compared to dacryocystorhinostomy.
