title: Lacrimal silicone intubation for anatomically successful but functionally failed external dacryocystorhinostomy.
abstract: OBJECTIVE
  To investigate the efficacy of lacrimal silicone intubation for the management of epiphora in patients who have previously undergone anatomically successful dacryocystorhinostomy (DCR).
  
  
  METHODS
  The authors recruited 13 patients (4 male, 9 female) who had persistent epiphora after an anatomically successful primary external DCR and conducted lacrimal silicone intubation through the dacryocystorhinostomy site.
  
  
  RESULTS
  Mean patient age was 54.2 years (range 42-80) and mean follow-up was 13.8 months (range 6-30). Epiphora was resolved in all 13 patients following silicone intubation. Spontaneous tube extrusion occurred in three patients, but a new one was easily reintubated.
  
  
  CONCLUSIONS
  Lacrimal silicone intubation is a simple safe and effective procedure for patients with epiphora even after anatomically successful DCR.
