Summary
Revision DCR success rates are similar across approaches when the same method is used. However, external revision is superior for primary transcanalicular laser DCRs.
Area of Science:
- Ophthalmology and Visual Science
- Otolaryngology
Background:
- Dacryocystorhinostomy (DCR) is a surgical procedure to restore tear drainage.
- Revision DCR may be necessary when initial surgery fails.
- Comparing different DCR revision techniques is crucial for optimizing outcomes.
Approach:
- This study conducted a systematic review and meta-analysis of existing DCR literature.
- Included studies specified primary and revision DCR techniques.
- Success proportions for each revision type, stratified by primary surgery, were analyzed.
Key Points:
- Overall DCR revision success rates did not significantly differ between external, endoscopic endonasal, and laser transcanalicular approaches when the same technique was used for revision.
- Primary surgery type did not significantly impact overall revision success.
- A notable exception: external revision outperformed laser transcanalicular revision for primary laser transcanalicular DCRs.
Conclusions:
- Surgeons can select their preferred DCR revision method based on comfort.
- For primary transcanalicular laser DCR failures, the external revision approach is recommended.
- Optimizing DCR revision strategies improves patient outcomes.
