[Results of dacryocystorhinostomy according to Toti from 2000 to 2012].

Background: The aim of this study was to describe the efficiency, long-term success, patient satisfaction and recurrence rate after dacryocystorhinostomy according to Toti in a retrospective analysis.

Material And Methods: At the Eye Clinic of the Paracelsus Medical University Salzburg 188 eyes of 176 patients with stenosis/obstruction of lacrimal duct were surgically treated between January 2000 and December 2012. Of these patients 173 eyes had no surgery before DCR according to Toti and 15 eyes had already been operated with diverse dacryocystorhinostomies. All patients underwent dacryocystorhinostomy according to Toti. Pre- and postoperative clinical finings were analysed retrospectively. Postoperative long-term results regarding patient satisfaction, absence of inflammation, epiphora and annoyance through local scar building had been evaluated with a questionnaire in a cross-sectional analysis.

Results: The primary success rate of DCR according to Toti was 91,9 % and the secondary success rate 98,3 % in patients without surgery preoperatively. Classifying by localisation of stenosis, better results could be reached in patients with postsaccal stenosis/obstructions (94,3 %) than in those with presaccal obstructions (77,8 %) or with mixed pre- and postsaccal stenosis/obstructions (86,7 %). Also in the patient group with previous surgery primary and secondary success rates of 93,3 % could be achieved after DCR according to Toti.

Conclusions: This study confirms that DCR according to Toti is a highly successful technique minimising epiphora and discomfort. The best success rate was found in patients with postsaccal stenosis/obstructions. The local scar was not found to be disturbing.
