To describe a new endoscopic procedure to restore the passage of tears in an obstructed lacrimal drainage system and to compare its efficacy with the standard external dacryocystorhinostomy (SE-DCR).
Patients with complete and partial primary acquired nasolacrimal duct obstruction (PANDO) were randomly allocated to 2 treatment groups using completely randomized design. The first group was treated using endoscopic lacrimal duct recanalization (ELDR), while the second group was treated using SE-DCR. Follow-up was conducted for at least 6 months and evaluated for anatomical and functional patency. Complications were also noted for both groups.
A total of 86 patients underwent ELDR, 60 of whom had complete PANDO, while 26 patients had partial PANDO. Eighty patients underwent SE-DCR; 58 had complete PANDO, and 22 had partial PANDO. The combined success rate in terms of anatomical patency for ELDR was 93.02% (95% confidence interval [CI], 0.88–98) compared with 93.75% (95% CI, 0.87–90) for SE-DCR (p = 0.85). Meanwhile, the combined success rate (functional patency) for ELDR is 84.88% (95% CI, 0.77–93) versus 90.00% (95% CI, 0.83–97) for SE-DCR (p = 0.32).
ELDR using microendoscope is as efficacious as SE-DCR, without its associated major complications.
Endoscopic lacrimal duct recanalization using microendoscope is effective with a high success rate comparable with standard external dacryocystorhinostomy.
