Abstract
Dacryocystorhinostomy (DCR) is a surgical procedure that restores communication between the tear sac and the adjacent nasal cavity. Our work consists of a comparative study of the results of external dacryocystorhinostomy (EX-DCR) versus endoscopic endonasal dacryocystorhinostomy (EN-DCR), whose rate of therapeutic failure by endoscopic route estimated at 20% against only 7% in the case of external surgery.

The endonasal approach to the tear ducts presents itself as a new physiological and aesthetic approach that is just as reliable as the external route and which benefits from suitable instrumentation with an operating method as standardized as the external route
Our work consists of a comparative study of the results of dacryocystorhinostomy by external route versus by endonasal route
Summary
Dacryocystorhinostomy (DCR) is a surgical procedure that restores communication between the tear sac and the adjacent nasal cavity. This definitive short-circuit of the lacrymonasal duct is obtained by removing the portion of bone and the mucous membrane interposed between these two natural cavities. External dacryocystorhinostomy has shown its long-term efficacy with a success rate of over 90%. The endonasal approach to the tear ducts presents itself as a new physiological and aesthetic approach that is just as reliable as the external route and which benefits from suitable instrumentation with an operating method as standardized as the external route. Our work consists of a comparative study of the results of dacryocystorhinostomy by external route versus by endonasal route
