title: [Transcanalicular laser-assisted dacryocystorhinostomy: initial results].
abstract: OBJECTIVE
  To describe the technique and initial results of laser-assisted dacryocystorhinostomy performed through the canaliculi.
  
  
  METHODS
  Ten patients with nasolacrimal duct obstruction underwent transcanalicular laser-assisted dacryocystorhinostomy. A silicone tube was inserted through the canaliculi and the ostium into the nasal cavity where it will be kept for 6 months.
  
  
  RESULTS
  All ten operations were performed without negative occurrences. One patient presented displacement of the silicone tube one day after surgery. Nine of the ten patients reported disappearance of epiphora at the end of the first week following surgery. During the first month, one of these patients presented with epiphora due to obstruction of the lacrimal-nasal fistula and another lost the silicone tube in the first month following surgery.
  
  
  CONCLUSIONS
  Transcanalicular laser-assisted dacryocystorhinostomy is a potentially useful method to perform dacryocystorhinostomy.
