LACRIMAL TRAUMA OVERVIEW
Jump To
Overview
Lacrimal trauma involved damage to the normal tear duct drainage. It can occur from all sorts of blunt or penetrating injuries, such as dog bites, blows from the fist, car accidents, etc. These can cause canalicular lacerations, lacrimal sac injuries, and/or nasolacrimal duct injuries.
Treatment
At Idaho Eyelid and Facial Plastic Surgery, repair may require relocation of the eyelid as well as the conduit. Placement of a silastic tubing (or a stent) helps conduit alignment and prevent narrowing after the repair. There are two types of stents, namely bi-canalicular stents and mono-canalicular stents. Bi-canalicular stents involve placement of a silicone stent in both the traumatized and the untraumatized canalicular system. Mono-canalicular stents involves placement a silicone stent only in the traumatized canalicular system thereby avoiding potential damage to the untraumatized canalicular system.
