Long-term results of endonasal dacryocystorhinostomy.

The aim of this study is to review the long-term results of endonasal endoscopic dacryocystorhinostomy (DCR) according to our experience as well as to evaluate potential prognostic factors for long-term outcomes. The files of 165 patients who underwent endonasal DCR at a tertiary referral centre between 1991 and 2001 were retrospectively assessed. Furthermore, these cases were clinically evaluated at least 5 years after surgery and completed a subjective result evaluation questionnaire. A cure was reported by a total of 112 (67.9%) subjects and significant improvement without need for further treatment was noted in 23 cases (13.9%). Thirty (18.2%) cases were considered as failures. The overall successful outcome according to the subjective symptom evaluation was 81.8%. Poor correlation between clinical findings and subjective report of symptoms was found. None of the prognostic factors that were assessed affected outcomes significantly. In conclusion, long-term success rates for endonasal DCR seem to be comparable to previously published short-term results.
