We want to evaluate the influence of the size of the osteotomy on the postsurgical outcomes.
A retrospective study was performed in patients who underwent TCL-DCR from January 1, 2008, to March 1, 2019. The patients were divided into two groups: the patients in one group were subjected to LP surgery with an osteotomy diameter equal to 9 mm ± 1 mm (group A), and the patients in the other group were subjected to surgery with an osteotomy diameter equal to 14 mm ± 1 mm (group B).
A total of 159 lacrimal pathways (LPs) were operated on in group A with a success rate (SR) of 66.6%. Thirty-three LPs were operated on in group B with an SR of 81.8%.
An osteotomy diameter equal to 14 mm ± 1 mm achieved better postoperative results than an osteotomy diameter equal to 9 mm ± 1 mm.
•The main reason for TCL-DCR postoperative failure is the stenosis of the ostium.•A larger osteotomy diameter was the key to improving our SR.•Osteotomy diameters equal to 14 mm ± 1 mm achieved better postoperative outcomes.
