To study the morphology and histopathological features of closed ostium and to know the efficacy of the combined approach is the purpose of the present case study. Patient subjected for endoscopic dacryocystorhinostomy combined with silicone stent intubation. Silicone tube left intact and the patient followed up for six months. Successful patency of the lower lacrimal drainage system achieved with complete resolution of epiphora after six months of follow up. Patency tested by lacrimal sac syringing and the ostium morphology studied by transnasal endoscope. Endoscopic dacryocystorhinostomy with silicone intubation and lacrimal sac syringing on weekly basis was beneficial and successful in achieving and maintaining the patency of lower lacrimal drainage system in failed external dacryocystorhinostomy.
