INTRODUCTION Acquired nasolacrimal duct obstruction is a common disorder affecting adults. Its pathogenesis is not known. We hypothesize that facial and bony asymmetry can contribute to the unilaterality of the nasolacrimal duct obstruction. MATERIALS AND METHODS Retrospective study was done on all patients with acquired nasolacrimal duct obstruction who presented to our practice from January...

PURPOSE To evaluate the results of nasolacrimal polyurethane stent implantations for the treatment of primary acquired nasolacrimal duct obstruction, and to determine the effects of various surgical procedures, including stent removal, in subsequent nasolacrimal duct obstruction. METHODS This study included 15 patients who had nasolacrimal polyurethane implantations for the treatment of prima...

purpose: to determine long-term outcomes of probing in adult patients with nasolacrimal duct (nld) obstruction. methods: patients older than 20 years admitted in labaffinejad hospital with complete nasolacrimal duct obstruction were studied. the selected patients underwent probing under local anesthesia and cases with successful nld probing enrolled the study. patients were examined during the ...

Introduction Mucoceles are benign expansive cystic formations, composed of a mucus-secreting epithelium (respiratory or pseudostratified epithelium). Nasolacrimal mucocele occurs in a small proportion of children with nasolacrimal duct obstruction and is characterized by a cystic mass in the medial canthus with dilation of the nasolacrimal duct; although dacryocystoceles are rare in adults, the...

This was clearly demonstrated in the survey by Dotan and Nelson in this issu...

Congenital Nasolacrimal Duct Obstruction is a frequent occurrence in newborns. This article discusses the incidence, etiology and management of congenital nasolacrimal duct obstruction. Though surgical intervention may be needed at times, a conservative approach is often
