Abstract

PURPOSE: To compare the surgical results of lacrimal surgery for nasolacrimal duct obstruction with and without canalicular stenosis.
METHODS
We surveyed 175 eyes which underwent external dacryocystorhinostomy with silicone tube intubation from January 1996 through December 2000 retrospectively. Group 1 included 126 eyes in nasolacrimal duct obstruction without canalicular or commoon canalicular stenosis and group 2 included 47 eyes with canalicular or common canalicular stenosis. We checked the statistical significance with Chi-squre Test.
RESULTS
Anatomical success rate was 96.0% (121/126) in group 1 and 85.7% (42/49) in group 2; It was statistically significant (p<0.05). And functional success rate was 91.3% (115/126) in group 1 and 73.5% (36/49) in group 2; it had statistic significance (p<0.05). The surgical success rate depending on the size of sac was not statstically significant in goup 1, but it had statstic significance in total group (p<0.05). In site of stenosis, anatomical and functional success rate ware 93.1% (27/29) and 79.37% (23/29) in common canalicular stenosis. It was higer surgical success rate than the other site, but it had no statistic significance.
CONCLUSIONS
The canalicular or common canalicular stenosis is important factor in success of lacrimal surgery. Therefore it is recommendable to open the canalicular stenosis by probing prior to performing dacryocystorhinostomy.
