Abstract

Objective: To describe the clinical characteristics and evaluate the surgical outcomes of traumatic canalicular laceration repair using silicone tube stenting at Viet Tiep Friendship Hospital.

Methods: Cross-sectional descriptive study was conducted on 30 patients with traumatic canalicular laceration who underwent canalicular repair using silicone tube stenting from January 2025 to March 2026 at the Department of Ophthalmology, Viet Tiep Friendship Hospital.

Results: Traffic accidents were the most common cause of canalicular laceration, accounting for 16/30 cases (53.3%), followed by domestic accidents with 11/30 cases (36.7%). Violence and occupational accidents were less frequent, accounting for 6.7% and 3.3%, respectively. Lower canalicular laceration predominated, occurring in 29/30 eyes (96.7%), whereas only 1 eye (3.3%) had upper canalicular laceration; no cases of simultaneous laceration of both canaliculi were observed. Regarding the site of injury, laceration of the inner one-third was most common, observed in 20 eyes (66.7%), followed by the middle one-third in 7 eyes (23.3%) and the outer one-third in 3 eyes (10.0%). Postoperative functional outcomes were good in 24 eyes (80.0%), fair in 4 eyes (13.3%), and poor in 2 eyes (6.7%). Anatomically, 27 eyes (90.0%) demonstrated patent lacrimal drainage on irrigation, with fluid passing normally into the throat, whereas 3 eyes (10.0%) had lacrimal obstruction. In terms of cosmetic outcome, 25 eyes (83.3%) achieved satisfactory anatomical restoration, while 5 eyes (16.7%) did not meet the criteria due to punctal eversion or failure of the punctum to appose the lacrimal lake.

Postoperative complications were infrequent. Four of 30 patients (13.3%) experienced foreign body sensation and irritation caused by the silicone tube tip contacting the globe, and 1 of 30 patients (3.3%) had early silicone tube extrusion approximately one month after surgery.

Conclusion: Traumatic canalicular laceration repair using silicone tube stenting is an effective treatment method that provides good restoration of lacrimal drainage function, anatomy, and cosmesis. Some silicone tube-related complications, such as foreign body sensation, irritation, or tube extrusion, may occur; however, their incidence is low and they are largely preventable.
