Double Silicone Intubation for Management of Recurrent Acquired Nasolacrimal Duct Obstruction

Abstract

Background: the obstruction of the nasolacrimal excretory system may occur in the proximal puncta, canaliculi, common canaliculus, or more distally within the lacrimal sac or nasolacrimal duct. Nasolacrimal duct obstruction occurs as a congenital or acquired disease. Acquired causes can be numerous. Aim of the Work: to evaluate Dacryocystorhinostomy (DCR) with double silicone tube in the management of recurrent epiphora after failed conventional DCR. Patients and Methods: This is a prospective study which was done on 30 patients with recurrent or persistent acquired epiphora who gave positive past history of previous DCR. Results: Epiphora improved significantly in 27 out of 30 patients (90%) after six month postoperatively. Conclusions: DCR is the gold treatment intervention for acquired nasolacrimal duct obstruction (NLDO) in adults, Silicone intubation (SI) increases success rates and double SI further increases the success rates of DCR for recurrent cases and is considered safe and effective technique.
