[Lacrimal-nasal canal stenosis after intranasal surgery]

The etiology of the nasolacrimal duct obstruction usually reported is: idiopathic, infectious, traumatic, congenital, tumoral and others. The nasolacrimal duct stenosis after intranasal surgery is rarely reported in the literature. We describe 5 cases of iatrogenic nasolacrimal duct stenosis found in our series of 41 patients treated the last 2 years for nasolacrimal duct obstruction and we propose how to avoid this complication of intranasal surgery.
