Canalicular Lacerations

Overview

  • Canalicular lacerations are breaks (interruptions) in the normal tear duct drainage system. If not repaired promptly, tearing will usually lead to.
  • This systems originates with the puncta (there is one in both the upper and the lower eyelid) and is a conduit for tears to travel from the eyelid through the nasolacrimal sac into the nose.
  • Tension, from trauma such as a blow from the fist, can lead to in an eyelid laceration which involves the canalicular system.
  • Repair requires re-approximation of the eyelid as well as re-approximation of the conduit; this is best achieved with a stent such as with silastic and fine sutures such as 6,7, or 8-0 vicryls.

Treatment

There are several different means to repair such an injury. Placement of a stent (silastic tubing) helps maintain proper alignment of the conduit and prevent stricture after the repair.

  • Bi-canalicular stent
    This places places a silicone stent in both the traumatized (lacerated) canalicular system as well as the normal. One disadvantage of this technique is the potential damage to the "good" canalicular system.
  • Mono-canalicular stent
    This places places a silicone stent ONLY in the traumatized (lacerated) canalicular system and thus avoids potential damage to the "good" canalicular system. A mini-Monoka or Monoka monocanalicular stent is typically used

    These three photos show a canalicular laceration and its repair with a Monoka monocanalicular stent.
