Long-term Results of the External Dacryocystorhinostomy - A Retrospective Study from 1991-2000 at the University Eye Hospital in Halle
Horix D., Struck H. G.,
Martin-Luther-Universität, Klinik und Poliklinik für Augenheilkunde (Halle/Saale)
Purpose: By means of a retrospective study the indication and the functional prognosis of external dacryocystorhinostomy were determined and compared with the results in the literature.
Method: From 1991 to 2000, a total of 203 patients underwent transcutaneous dacryocystorhinostomy at the University Eye Hospital in Halle (228 operations). We evaluated to medical data and asked the patients the satisfaction with the operation, the other necessary treatments and the recent symptoms via questionnaire.
Results: Of 203 patients, 142 were female (70%) and 61 male (30 %). Mean age at the time of the surgery was 51.3 years, oldest 93.0 years and youngest 1.3 years. Mean follow-up time was 3.8 years varying from 1.0 to 10.9 years. We sent 223 questionnaires with a feedback of 146 utilizable answers (65.5 %). Because a reoperation was necessarily, we didn`t send a questionnaire for 5 failed operations. After 121 operations (82.8 %) the patients were symtomfree or seldom they had a little epiphora in the wind and cold weather. 8 patients (5.5 %) had scare problems (painfulness, paraesthesia, bad esthetical result).
Conclusions: The functional success rate was 80.1 % in a postoperative mean follow-up time of 3.8 years. This long term patency rate is comparable with the results for the external dacryocystorhinostomy in the literature from 80 to 100 %. Other alternative surgical procederes have to measure to these high success rates.
