Balloon Dacryocystoplasty with Pushed Monocanalicular Intubation as a Primary Management for Primary Acquired Nasolacrimal Duct Obstruction

Abstract Though dacryocystorhinostomy (DCR) has long served as the gold treatment for primary nasolacrimal duct obstruction (PANDO), balloon dacryocystoplasty (DCP) and silicone stent intubation were applied especially in partial PANDO in the attempts to avoid osteotomy and reduce invasiveness. Herein, we present the results of the combined procedures with balloon DCP and pushed monocanalicular intubation in complete PANDO, and comparison of the combination to balloon DCP alone. We retrospectively reviewed 72 eyes of 56 patients, including 37 eyes of 29 patients in the combination group and 35 eyes of 28 patients in the balloon DCP alone group. There was no significant difference in the success rate between antegrade balloon DCP with and without pushed MCI in general. Nevertheless, interestingly the former procedure was associated with significantly higher surgical success rate than the latter in younger patients.
