Powered endoscopic dacryocystorhinostomy (DCR) offers success rates comparable to the external approach, with favorable long-term outcomes and no external scar. This technique is a viable alternative for primary and revision cases.
Area of Science:
- Ophthalmology
- Otorhinolaryngology
Background:
- Dacryocystorhinostomy (DCR) is a surgical procedure to restore tear drainage.
- Endoscopic and external approaches are common DCR methods.
Purpose of the Study:
- To review recent literature on powered endoscopic dacryocystorhinostomy (DCR).
- To describe the powered endoscopic DCR approach and compare its outcomes to external DCR.
Main Methods:
- Literature review of recent studies.
- Meta-analysis of DCR outcomes.
- Comparison of endoscopic DCR (powered and laser-assisted) with external DCR.
Main Results:
- Powered endoscopic DCR success rates are comparable to external DCR.
- Laser-assisted endoscopic DCR showed a lower success rate.
- Long-term results of powered endoscopic DCR are favorable in primary and revision cases.
Conclusions:
- Powered endoscopic DCR is comparable to external DCR.
- It avoids external scarring and allows for simultaneous procedures.
- The study describes the powered endoscopic approach and methods to optimize success.
