Fusiform Anastomosis Technique with a Single Longitudinal Incision in the Lacrimal Sac in External Dacryocystorhinostomy.

Background: In the present study, we aimed to evaluate the surgical outcomes of the fusiform anastomosis technique in external dacryocystorhinostomy (ex-DCR) that we designed in the form of a physiological tube, which sufficiently covered the bone ostium with the mucosa.

Material And Methods: This was a retrospective observational study that included 145 eyes of 131 patients who underwent ex-DCR due to nasolacrimal duct obstruction. The patients were divided into two groups.
