Medial lacrimal sac excision versus conventional H-shaped lacrimal sac opening in external dacryocystorhinostomy: a comparative cohort study.

Purpose: The external dacryocystorhinostomy (Ex-DCR) is a reliable but surgically challenging procedure to overcome a nasolacrimal duct obstruction (NLDO). The aim of this study is to describe the outcomes of a modified technique of lacrimal sac opening and to compare it with the conventional Ex-DCR.

Methods: This comparative cohort study included adult patients undergoing Ex-DCR for primary acquired NLDO by or under supervision of one surgeon.
