Summary

External dacryocystorhinostomy (DCR) remains the gold standard for nasolacrimal duct obstruction, showing superior long-term success rates compared to laser-assisted endonasal and transcanalicular approaches.

Area of Science:

Ophthalmology
Otorhinolaryngology

Background:

Distal nasolacrimal duct obstruction can impair quality of life.
Surgical intervention is often necessary to restore lacrimal drainage.

Purpose of the Study:

To compare the efficacy of different surgical techniques for distal nasolacrimal duct obstruction.
To evaluate external dacryocystorhinostomy (DCR), endonasal laser-assisted DCR, and transcanalicular laser-assisted DCR.

Main Methods:

Comparative analysis of surgical techniques.
Review of personal surgical experiences and existing literature.
Evaluation based on success rates (long-term patency), perioperative conditions, and patient selection.

Main Results:

Conventional external DCR demonstrates higher success rates compared to laser-assisted endonasal and transcanalicular DCR.
External DCR offers better long-term patency for distal nasolacrimal duct obstructions.

Conclusions:

External DCR is currently the gold standard for treating distal nasolacrimal duct obstruction.
While laser-assisted techniques offer alternatives, external DCR remains the benchmark for comparison due to superior outcomes.
