Outcomes of 8 × 8 mm osteotomy in powered external dacryocystorhinostomy.

ABSTRACT:

Purpose

To study the endoscopic ostium characteristics and outcome of 8 × 8 mm osteotomy in external dacryocystorhinostomy (DCR) using the microdrill system.

Methods

This prospective interventional pilot study was performed on 40 eyes of 40 patients with primary acquired nasolacrimal duct obstruction (NLDO) from June 2021 to September 2021 in patients undergoing external DCR. An 8 × 8 mm osteotomy was performed using round, cutting burr attached to a microdrill system. Success was defined as patent ostium on lacrimal syringing (anatomical) and a Munk score <3 (functional) at 12 months. Postoperative endoscopic ostium evaluation was done using a modified DCR ostium (DOS) scoring system at 12 months.

Results

The mean age of the study participants was 42.41 ± 11.77 years
