Probing of the nasolacrimal duct is a common procedure in children with congenital stenosis. Although simple probing of the nasolacrimal duct is successful in a majority of patients, a number of failures occur. In those temporary intubation of the nasolacrimal duct with a silicone drain may solve the problem. We performed silicone intubation in 11 infants under nasal endoscopic control. By this...

In our previous study the inclination of nasolacrimal canal in relation to Frankfurt horizontal plane has been analysed on 71 anatomically preparated human skulls by introducing the probe through canal. The results of that study showed that the alpha angle in the frontalplane was greater than 91 degrees in 27% of cases, i.e., nasolacrimal canals descend diverging in relation to the median plane...

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...

Objective- Radiological and anatomical study of the Lacrimal apparatus system in one-humped camel of Iran (Camelus Dromedarius).Design- Prospective studyAnimals- Five heads (cut above the third cervical vertebra) of adult Dromedary camels' cadavers were collected from the slaughterhouse of the Najafabad area of Isfahan Province, Iran. Procedures- The anatomy of the nasolacrimal duct of one- hum...

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...

IMPORTANCE Approximately 5% to 10% of patients continue to experience persistent epiphora following an anatomically successful dacryocystorhinostomy (DCR) for nasolacrimal duct obstruction or stenosis. OBJECTIVE To investigate the management and success rate of so-called "functional failure" of DCR for nasolacrimal duct obstruction by experienced lacrimal surgeons. DESIGN, SETTING, AND PART...
