Purpose: In the present study, we cultured specimens and evaluated the types of bacteria existing at the stent and their antibiotic sensitivities from removed nasolacrimal polyurethane stents (Song's stents) due to recurrent inflammation or Song's stent obstruction after placement of Song's stents without fluoroscopic guidance for the treatment of obstructed nasolacrimal ducts. Methods: In 11 eyes of 11 patients who received Song's stent intubation to resolve nasolacrimal duct obstruction, the Song's stents were removed due to either recurred symptoms, signs of chronic dacryocystitis, or tube obstruction. Song's stents were cultured to identify bacteria and tested for their antibiotic sensitivity. Results: The Song's stent removal was from 3 years 7 months to 17 years 1 month after intubation, thus the average duration was 10 years. The species of cultured bacteria were Pseudomonas in 7 eyes, Staphylococcus aureus in 2 eyes, and Stenotrophomonas maltophilia in 2 eyes. In antibiotics sensitivity tests, 5 of 7 eyes with Pseudomonas were resistant to trimethoprime/sulfamethoxazole (Bactrim, Roche, Basel, Switzerland) and 2 eyes with Staphylococcus aureus were resistant to penicillin. Ten eyes underwent silicone tube intubation simultaneously during Song's stent removal and 1 eye underwent Song's stent removal only. Conclusions: The most common bacteriological etiology of Song's stent obstruction or recurrent inflammation is Pseudomonas species. The use of efficient antibiotics is necessary to avoid antibiotic intolerance and simultaneous silicone tube intubation during Song's stent removal and is essential for the management of epiphora.

Purpose: This study was carried out to evaluate and investigate the long-term outcome of placement of 25 plastic nasolacrimal stents (Song`s stents) without fluoroscopic guidance for the treatment of obstructed nasolacrimal ducts. Methods: The medical records of 25 patients who had had Song`s polyurethane stents placed between 1997 and 2003 were reviewed. The patients included 17 women and 8 men who ranged in age from 22 to 79 years (mean, 57.9 years). The mean follow-up period was 54 months. Re...

Purpose: We evaluated cultured specimens from removed Jones tubes and their antibiotic sensitivities. Methods: In 16 patients who had received lacrimal bypass surgery to resolve nasolacrimal duct obstruction, the Jones tubes were removed due to either recurred symptoms, signs of chronic dacryocystitis, the tubes being obstructed, or migration of the tubes. Jones tubes were cultured to identify bacteria and tested for their antibiotic sensitivity. Results: The average duration from intubation to ...

Purpose: To evaluate the results of nasolacrimal polyurethane stent implantations for the treatment of primary acquired nasolacrimal duct obstruction, and to determine the effects of various surgical procedures, including stent removal, in subsequent nasolacrimal duct obstruction. Methods: This study included 15 patients who had nasolacrimal polyurethane implantations for the treatment of primary acquired nasolacrimal duct obstruction. Occluded stents were removed either by nasal endoscopy or du...

Purpose: This study investigated the cytological findings of the nasolacrimal duct by using the removed silicone tube in patients of nasolacrimal duct obstruction according to the surgical technique. Methods: Cytologic study was performed in 49 eyes of 41 patients who underwent silicone tube intubation or dacryocystorhinostomy from May 2002 to April 2003. By using Thin Prep 2000 (CYTYC. USA), the cells around the removed silicone tube inserted in the operation were observed by light microscope. ...

Purpose To evaluate the results of nasolacrimal polyurethane stent implantation for the treatment of primary acquired nasolacrimal duct obstruction and the effects of obstructed nasolacrimal stent on subsequent dacryocystorhinostomy (DCR). Methods This study was designed as a nonrandomized, prospective clinical trial. Stent implantation was attempted in 53 obstructed lacrimal drainage systems of 47 patients. Stent placement was performed in a retrograde fashion through the external nare over a g...

Purpose: To search the histopathologic change of the nasolacrimal duct after silicone tube intubation by the microscopic examination of removed silicone tube. Method: Sixty nasolacrimal duct oBstruction (NLDO) patients (11 congenital and 49 acquired NLDO) operated by silicone tube intubation and conventional dacryocystorhinostomy were participated. Duration of silicone tube intubation and the length of the removed silicone tube were measured. Removed silicone tubes were stained with H&E to inspe...

Abstract PURPOSE: To evaluate the efficacy of polyurethane nasolacrimal duct stents in the treatment of epiphora resulting from primary acquired nasolacrimal duct obstruction in adults. MATERIALS AND METHODS: In 25 patients (21 women and four men with mean age of 44 years, range 20 to 74 years) with nasolacrimal duct obstruction, 28 hollow polyurethane stents designed by Song and associates were placed under fluoroscopic guidance. The obstruction was complete in 20 lacrimal drainage systems and ...

Abstract Purpose To evaluate the clinical efficacy of the polyurethane (Song) stent in the treatment of nasolacrimal duct obstruction without fluoroscopic guidance, especially at the junction between the lacrimal sac and nasolacrimal duct or at the nasolacrimal duct. Design Retrospective noncomparative case series. Participants This study evaluated 59 cases of nasolacrimal duct obstruction in 53 patients, with mean epiphora of 36 months (range, 2 months–17 years). Methods Without the assistance ...

Background: The polyurethane nasolacrimal duct stent is used as an alternative to conventional techniques for treatment of lower tear duct obstruction. The aim of this study was to evaluate the clinical success rate after a follow-up of 2 years. Methods: Nasolacrimal duct stent implantation was attempted in 19 patients with nasolacrimal duct obstruction proven by digital substraction dacryocystography. The median age of the patients was 50 years, and the minimum duration of symptoms was 3 months...
