The osteotomy diameter in the transcanalicular laser dacryocystorhinostomy. Our experience in 192 lacrimal pathways.

OBJECTIVES

We want to evaluate the influence of the size of the osteotomy on the postsurgical outcomes.

METHODS

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).

RESULTS

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%.

CONCLUSION

An osteotomy diameter equal to 14 mm ± 1 mm achieved better postoperative results than an osteotomy diameter equal to 9 mm ± 1 mm.
