Abstract

Purpose
To investigate the surgical outcomes of endonasal dacryocystorhinostomy with canalicular trephination in patients with canalicular obstruction.
Methods
We retrospectively analyzed the medical records of 37 eyes from 32 patients who were diagnosed with canalicular obstruction between May 2010 and July 2022 and underwent endonasal dacryocystorhinostomy with canalicular trephination to evaluate the success rate and complications.
Results
In the total patient group, 81.1% achieved complete success in which epiphora completely disappeared, 13.5% had partial success in which epiphora remained but improved, and 5.4% experienced failure in which tearing persisted or worsened. Complications included one case of dacryocystorhinostomy bony opening granuloma and one case of dacryocystorhinostomy bony opening inflammation.
Conclusions
Endonasal dacryocystorhinosomy with canalicular trephination is an effective method for treating canalicular obstruction, offering a high success rate and few complications. It can be considered before resorting to conjunctivodacryocystorhinostomy, which is a more conventional treatment.
