SA.08.10 Long-term results after dacryocystorhinostomy (DCR) ab externo and ab interno Voltmer J.1, Buchner T.1, Welkoborsky H.-J.2, Wiechens B.1
1Department of Ophthalmology, Klinikum Region Hannover; 2Department of Otorhinolaryngology, Klinikum Region Hannover Objective: The present retrospective study was performed to compare long-term functional results of dacryocystorhinostomy (DCR) using various techniques: transcutaneous (Toti) with or without intubation, and endonasal (West) with intubation.
Methods: 96 patients who were operated for lacrimal duct obstruction in the Eye Hospital or ENT Hospital, Klinikum Region Hannover, between 1999 und 2003 (100 consecutive procedures) had a follow-up examination. Patients were 23 to 86 (mean 55) years old. The duration of the follow-up period was 6 to 73 (mean 36) months. Patients were divided into 4 groups. Group 1: Toti external DCR without intubation (n=52), Group 2: Toti external DCR using a Y-shaped intubation system (n=11), Group 3: Toti external DCR with bicanalicular silicone intubation (n=14), Group 4: West endonasal DCR with bicanalicular silicone intubation (n=23).
Results: At the end of follow-up the success rates (patency of the lacrimal drainage system) were:
58% in group 1,
45% in group 2,
80% in group 3,
73% in group 4.
Recurrences developed after 7 to 15 months. There were no other complications (e.g. infections or bleeding).
Conclusions: The present study shows significantly better results after external or endonasal DCR with silicone intubation than after implantation of the Y-shaped device or surgery without intubation. We recommend a silicone intubation in the context of a DCR. The Y-shaped intubation system was less favourable since it might cause tissue irritation and recurrent stenosis.
