Application of implantation of high-density porous polyethylene artificial nasolacrimal canal for complex orbital fracture combined with lacrimal duct obstruction

Abstract

Objective To evaluate the curative effect of high-density porous polyethylene artificial nasolacrimal canal (medpor) implantation for complex orbital fracture combined with lacrimal duct obstruction. Methods Seventeen eyes of 17 patients with traumatic lacrimal duct obstruction were treated with artificial nasolacrimal canal implantation. The patients were followed up for 6-36 months after the surgery. Results The epiphora disappeared or improved in all the patients. Postoperative complications including granulation hyperplasia and polyps growing in conjunctival side of the artificial nasolacrimal canal happened in 2 cases(11.8%) and scar covering around the nasolacrimal canal happened in 2 cases (11.8%). Conclusion Artificial nasolacrimal canal (medpor) implantation can obviously improve epiphora in patients with traumatic lacrimal duct obstruction. The method is safe and effective.
