Evaluating failed dacryocystorhinostomy using computed tomography dacryocystography: a preliminary analysis of bony ostium characteristics in an Asian population.

ABSTRACT:

Background

Although dacryocystorhinostomy (DCR) is the standard treatment for nasolacrimal duct obstruction, some surgeries are unsuccessful, and the reasons are not fully understood. By comparing successful and unsuccessful cases, this study investigated how computed tomography dacryocystography (CT-DCG) can help explain why these surgeries fail.

Methods

This retrospective study included 34 failed and 16 successful DCR cases. The bony ostium was analyzed using CT-DCG with 3-dimensional (3D) reconstructions. The ostium position, dimensions (width, height, total area, and shortest side), shape regularity, and presence of obstructing residual bone were measured and assessed. Preoperative nasal endoscopy was performed, and intraoperative findings were documented to supplement t
