title: Eyelid Lacerations Due to Dog Bite in Children.
abstract: OBJECTIVE
  To evaluate the nature and extent of lacrimal apparatus injury in children after eyelid laceration from a dog bite.
  
  
  METHODS
  A retrospective chart review of all eyelid lacerations treated between 1990 and 2012 at Boston Children's Hospital, Boston, Massachusetts, was conducted. Seventy-three patients who sustained an eyelid laceration due to dog bite were identified and were matched 5:1 with a randomly selected cohort of 365 patients from the group of 1,177 patients who had sustained eyelid lacerations from other causes during the same time period.
  
  
  RESULTS
  Of the 73 patients who sustained an eyelid laceration due to a dog bite, 26 (35.62%) had damage to the lacrimal apparatus. This was statistically significant when compared to patients who sustained eyelid lacerations from other causes, in which 13 (3.56%) patients had damage to the lacrimal apparatus (P < .000001). The inferior canaliculus was the most commonly involved site of lacrimal apparatus trauma as a result of a dog bite. Success was defined as lack of epiphora at the time of the last follow-up. Early surgical management of eyelid lacerations with lacrimal apparatus involvement had a success rate of 82%.
  
  
  CONCLUSIONS
  Eyelid lacerations due to dog bites have a greater prevalence of involvement of the lacrimal apparatus and especially the inferior canaliculus than lacerations due to other causes in children. Clinicians should have a high index of suspicion for lacrimal apparatus involvement and be prepared for surgical repair, if indicated.
