Abstract：Objective: To investigate the viability of removing foreign bodies located in the distal part of the upper lacrimal duct and meanwhile restoring the normal flow of tear drainage. Methods: From May 2008 to October 2021, a retrospective analysis was conducted in 17 patients (17 eyes) who underwent endoscopic transnasal dacryocystorhinostomy for the removal of foreign bodies in the distal part of the upper lacrimal duct at Eye Hospital,Wenzhou Medical University. Surgical outcomes were recorded, including whether the foreign bodies were removed, the type of foreign bodies, the success rate of tear drainage reconstruction, and surgical complications. Results: Atotal of 17 cases (7 right and 10 left eyes) with an average age of 38.5 ± 12.2 years (ranging from 21 to 60 years) and a duration of symptoms of 21.5 ± 4.8 days (ranging from 2 to 65 days). All surgeries were successfully completed without any complications, and all foreign bodies were successfully removed. The types of foreign body removed included circular metal foreign bodies in 7 eyes, broken small silicone tips in 5 eyes, broken pig bristles in 4 eyes, and broken probe small metal in 1 eyes.The postoperative follow-up period ranged from 12 to 24 months, with a mean of 16.1 ± 3.8 months. At the fnal review, none of the patients complained of tearing or pus discharge, and all had normal tear drainage by lacrimal irrigation. There were no obvious complications observed, such as stenosis or obstruction of the upper lacrimal duct, atresia of dacryocystonasal anastomosis, or any nasal disorders.Conclusions: Endoscopic transnasal dacryocystorhinostomy appears to be a viable method to remove foreign bodies located in the distal part of upper lacrimal duct, and it is recommended for clinical use.
