Treatment of recurrent nasolacrimal duct obstruction by inverted lacrimal intubation combined with drug administration within the tube

Objective To investigate clinical therapeutic effect of lacrimal intubation combined with drug administration within the tube on recurrent nasolacrimal duct obstruction.Methods 13 cases(15 eyes) of recurrent nasolacrimal duct obstruction were selected.Under topical anesthesia of lacrimal and nasal mucosa,a self-designed silicone tube with a plug on the nasal end was implanted retrogradly through nasal cavity.Mitomycin C and sensitive antibiotics were administrated into the tube and then the nasal end of the tube was stuffed.inverted irrigation was performed after the operation.The drugs remained in the tube had a direct and long-term effect on the mucosa of dacryocyst and nasolacrimal duct. Results For the 13 cases(15 eyes) of recurrent nasolacrimal duct obstruction,inverted lacrimal intubation combined with administration of mitomycin C within the tube can effectively control granulation and scar growth.By selecting sensitive antibiontics remained in the tube,satisfactory therapeutic effects have been got. Conclusion Recurrent nasolacrimal duct obstruction can be effectively cured by inverted lacrimal intubation combined with direct administration of mitomycin C and sensitive antibiotics.
