Abstract:

Objective   To investigate the efficacy and practicability of through nasolacrimal duct dilating with mitomycin C in treatment of nasolacrimal duct obstruction. Methods  60 patients  were randomly divided into two groups: Group A received mitomycin C and Group B received a silicone stent.After nasolacrimal duct dilating,   mitomycin C was used in Group A, and a silicone stent was retrogradely placed in Group B. Results   Followed up for 6 months, efficacy of the two groups was not significantly different through a Chi square test. Conclusion   Nasolacrimal duct dilating with mitomycin C has similar clinical efficacy with retrograde placement of a silicone stent.  It  has many advantages, such as simple operation, cheap charge, short treatmenttime, small trauma, and quick resumption.
