| Abstract |
|
Endonasal DCR has been reported for the advantages of lack of a cutaneous scar and short operating time but that the surgical success rates were lower than conventional method. We have performed endonasal DCR and had follow-up of at least 6 months in 107 patients who had been diagnosed with lacrimal pathway obstruction, and also surveyed the age, sex, sac size and nasal cavity abnormality to evaluate the factors related to success rate. Primary success rates were 82.2%(88eyes) and higher success rates were noted in younger age, man and large sac but not significant. But. the cases associated with nasal cavity abnormality as septal deviation, middle turbinate hypertrophy, ethmoiditis and polyp showed poor surgical results due to membranous ostium closure, formation of granuloma within the ostium, and formation of cicatrix with the middle turbinate.(P<0.05) Improvement of success rate may be owing to appropriate preoperative evaluation, proper management of nasal cavity abnormality preoperatively and intraoperatively, and show consider the conventional method in cases of that lower success rate are predict. |
