Summary

Nasolacrimal duct obstruction (NLDO) can manifest as epiphora or recurrent infections with mucopurulent discharge and may even cause social embarrassment. Dacryoendoscopic-assisted laser dacryoplasty with silicone intubation (DLDI) offers direct therapy to the obstructed site, leading to minimal collateral damage external to the target zone. Although the silicone intubation using dacryoendoscopy has increased the success rates, the success rates vary from a low of 51% to a high of 90%. The difference in success rates seems to depend on the site of obstruction, differences in the surgical technique, stringency of definitions of success, and duration of follow-up. The aim of our study was to report the results of DLDI for the management of NLDO, and to identify factors associated with DLDI failure.

Conditions

  • Lacrimal Duct Obstruction

Interventions

PROCEDURE

Dacryoendoscopic-assisted laser dacryoplasty with silicone intubation

The dacryoendoscopy was inserted into the lacrimal duct through the upper or lower lacrimal punctum. When the dacryoendoscopy reached the postsaccal obstruction, laser dacryoplasty (FOX diode laser, A.R.C. Laser, Nürnberg, Germany) was performed by widening the stenotic or obstructed section. After removing the dacryoendoscopy, a silicone tube inserted into lacrimal passage. Double bicanalicular silicone intubation was performed as previously described.
