Analysis of Age as a Possible Prognostic Factor for Transcanalicular Multidiode Laser Dacryocystorhinostomy

الملخص EN

Purpose.

To assess the prognostic value of age on the outcome of transcanalicular multidiode laser dacryocystorhinostomy (TCL-DCR) in patients with acquired nasolacrimal duct obstruction (NLDO).

Methods.

The medical records of TCL-DCR performed between March 2009 and September 2013 were reviewed retrospectively.

Inclusion criteria include over 20 years of age, similar mean follow-up period, and similar mean duration of stenting.

The main outcome is surgical success.

The effect of age on success rate is also evaluated.

Results.

The anatomical success was 52% in Group 1 (20–30 years), 56% in Group 2 (31–40 years), 64% in Group 3 (41–50 years), 76% in Group 4 (51–60 years), and 88% in Group 5 (over 60 years).

The statistical difference among Group 1 and Group 5, in terms of surgical success rate, was found to be significant ( P = 0 .

00 9 ).

Additionally, the 20–30-year-old patients had a failure rate 6.76 times higher than that of the over-60-year-old patients ( P = 0 .

00 9 ; 95% CI, 1.605–28.542).

Conclusion.

TCL-DCR is a surgical treatment option for NLDO for which a skin incision can be avoided.

The success rate of TCL-DCR for younger population is lower when compared with elderly population.
