Abstract

PURPOSE
The purpose of this study is to analyze the various forms of nasolacrimal duct obstruction in patients after they took dacryocystography and to find out the relations between the dacryocystographic finding and the results of the treatment. METHODS: From March 2001 to April 2002, 48 patients out of 53 cases who suffered from epipora were diagnosed to have nasolacrimal duct obstruction. The nasolacrimal duct obstruction was classified complete obstruction and partial obstruction that was divided into regular inner surface, irregular inner surface and secondary dilatation. Dacryocystorhinostomy was performed on the patients with complete obstruction and the others with partial obstruction got silicone tube intubation according to the dacryocystography. Success rate that was estimated as patient's satisfaction(0-3) was compared, and success was defined as score 1 or more. RESULTS: The Numbers of complete obstruction and partial obstruction were 25 and 28 respectively. As for the patients with partial obstruction, patients with regular inner surface(2.43+/-0.93) showed better statistical(P=0.00) results than those who had irregular inner surface(1.75+/-1.28) or secondary dilatation(1.00+/-0.89). However, the location of the obstruction was insignificant in the course of treatment. CONCLUSIONS: Dacryocystorhinostomy is preferred to silicone tube intubation in nasolacrimal duct obstruction patients. It is more appropriate to conduct dacryocrystorhinostomy on patients who have secondary nasolacrimal duct dilatation due to nasolacrimal duct obstruction on dacryocystography.
