[Lacrimal duct obstruction treated with lacrimonasal stent].

Abstract

OBJECTIVE:

To analyze a series of patients with lacrimal duct obstruction treated with polyurethane stents.

MATERIAL AND METHODS:

We studied 125 cases of lacrimal duct obstruction corresponding to 115 patients, of whom 30 were males (26.08%) and 85 females (73.91%). The obstruction involved the right side in 51 cases (40.8%) and the left side in 74 (59.2%). Mean age was 65 +/- 14.64 years. Symptoms included chronic epiphora in 65 patients (52%), acute lacrimal sac inflammation in 33 (26.4%), mucocele in 6 (4.8%) and recurrent conjunctivitis in 4 (3.2%). Seventeen patients came to us diagnosed with lacrimal duct obstruction. Time of follow up was one year.

RESULTS:

Stents were successfully implanted in 120 cases (96%). Surgical complications included pain in 5.83%, eyelid inflammation in 5%, nasal bleeding in 0.83% and false duct in 0.83%. Functional success was achieved in 82 patients (68.3%), and surgical failure occurred in 38 patients (31.7%). Mean time of stent failure was 178 days. In these cases, inner granulation tissue was found in 63.15% of the cases and mucoid material in 36.85%. The most common postoperative complication was mucocele formation, which ocurred in 7.5% of the patients.

CONCLUSIONS:

In our experience, polyurethane stent implantation is a good alternative for treating nasolacrimal obstruction, but not as effective as endonasal or external dacryocystorhinostomy.
