The standard intervention for non-complicated, unresolved cases is simple blind probing of nasolacrimal duct. The overall success rate of one time simple probing is 75%-95 %. Simple probing is performed through a blind passage of a malleable metallic probe through punctum to nasolacrimal duct and inferior meatal space in nasal cavity.Although effective, probing may be associated with traumatic nasal bleeding, nasal mucosal damage,punctal and canalicular injury and false passage. The trauma is further concerned during stent insertion.In the past decade improvement in endoscopic instruments and techniques enabled us to visualize and smoothly manipulate anomalies in the nasal cavity and especially in the inferior meatus. Endoscopic assisted probing has been proposed as a measure to increase accuracy, efficacy and safety of nasolacrimal probing. Furthermore, by this method intranasal pathologies associated with failure of probing could be accurately diagnosed and specifically treated. To the best of our knowledge literature addressing this issue is limited to few limited case series.
