title: [Endonasal dacryocystorhinostomies with transillumination and intubation in patients with combined pathologies of the nose and after revision].
abstract: BACKGROUND
  The results of endonasal dacryocystorhinostomies (DCR) with transillumination and intubation are presented.
  
  
  METHODS
  In the period from 1999 to 2009 follow-up examinations of 50 endonasal DCRs were carried out. All patients over 18 were included. The files were systematically evaluated. The follow-up examinations were performed after a minimum of 6 months with anamnesis of epiphora.
  
  
  RESULTS
  50 endonasal DCRs were performed on 40 patients. Initial surgery was performed on 27 lacrimal ducts, 16 patients had already had operations. Corrective surgery was required in 8 cases (7 endonasal DCRs, 1 external DCRs). 78 % women and 22 % men were included. The median age at the time of operation was 48 years; the median duration of preoperative symptoms was 24 months. In 42 % of the cases a chronic dacryocystitis was found. Pre-existing conditions were sarcoidosis in three cases and one case of Wegener's granulomatosis. As well as lacrimal duct obstruction, additional pathologies were treated in the same session [septoplasty (n = 12), sinus operations (n = 10), and cauterisation of the nasal concha (n = 7), removal of a dacryocele (n = 1), conchectomy (n = 1)]. 20 operations were performed on the right side, 26 on the left side and two bilateral. The median duration of the operation was 51 minutes. No operative complications were encountered. The length of stay in hospital was on average four days. The median of follow-up was 23 months. The success rate was 78 %.
  
  
  CONCLUSIONS
  The success rate of endonasal DCRs is about 70 to 95 %. Thus, the achieved rate in this study is acceptable, especially as 16 of 40 patients underwent revision surgery. Probably this is attributed to the technique of transillumination. The safe intraoperative localisation of the lacrimal sac with a light probe seems to have a positive effect on the removal of obstructions.
