title: [Endonasal dacryocystorhinostomy: technique and results].
abstract: BACKGROUND
  Endonasal dacryocystorhinostomy has recently become an important alternative to the classical external Toti procedure.
  
  
  OBJECTIVE
  To analyse the outcome after endonasal dacryocystorhinostomy.
  
  
  METHODS
  For this purpose 28 of 34 patients treated by endonasal dacryocystorhinostomy between May 1994 and November 1998 were investigated.
  
  
  RESULTS
  After an average follow-up of 28 months, 23 of the 28 patients (82%) are free of symptoms. Two additional patients became symptom-free after revision surgery. The total success rate is 89%. The only complications seen were 2 cases of asymptomatic synechiae and one case of mild hyposmia.
  
  
  CONCLUSIONS
  Endonasal dacryocystorhinostomy is a rapid, safe, and elegant method for the treatment of post-saccal nasolacrimal duct obstructions.
