# Acute and Past Common Lacrimal Canalicular Lacerations: A Report of Two Cases

## TL;DR

This paper presents two cases of lacrimal canalicular lacerations and their treatments, offering insights into managing such rare ocular injuries.

## Contribution

The paper introduces specific treatment approaches for acute and past lacrimal canalicular lacerations, based on two clinical cases.

## Key findings

- A bicanalicular stent was successfully used to treat an acute common lacrimal canalicular laceration.
- External dacryocystorhinostomy combined with monocanalicular stent insertion was effective for a previous canalicular laceration.
- These treatments may be preferable to conjunctivodacryocystorhinostomy in initial surgeries.

## Abstract

Lacrimal canalicular lacerations can be caused by trauma to the ocular adnexa, such as a penetrating or blunt injury. Only a few cases involving the common canaliculus or lacrimal sac have been reported, and only a few reports have described the detailed course of treatment. Here, we report an acute case of common lacrimal canalicular laceration and a case of a previous common canalicular laceration. The acute case was treated with a bicanalicular stent directly inserted into the nasolacrimal duct. The case with a previous common canalicular laceration was treated with external dacryocystorhinostomy combined with monocanalicular stent insertion. These treatments may be appropriate for the initial surgery and can be selected before performing conjunctivodacryocystorhinostomy.
