Endonasal laser dacryocystorhinostomy--medium term results
The British Journal of Ophthalmology
|March 14, 1998
Summary
Endonasal laser dacryocystorhinostomy (ELDCR) shows variable long-term success. Adjunctive treatments are needed to improve ostial patency and long-term outcomes for ELDCR compared to external DCR.
Area of Science:
- Ophthalmology
- Otorhinolaryngology
Background:
- Endonasal laser dacryocystorhinostomy (ELDCR) offers potential benefits over traditional external DCR.
- Long-term outcomes and late rhinostomy failure rates of ELDCR are not well-established.
Purpose of the Study:
- To evaluate the 3-month and 12-month results of ELDCR.
- To assess the long-term efficacy and failure rates of ELDCR.
Main Methods:
- Retrospective review of consecutive ELDCR procedures performed between November 1993 and May 1995.
- Analysis of demographic data, surgical details, and postoperative outcomes.
Main Results:
- Without lacrimal stenting, ELDCR had a 67% success rate at 3 months, increasing to 76% at 12 months.
- With lacrimal stenting, ELDCR showed an 82% success rate at 3 months, with a 21% failure rate by 12 months.
- Lacrimal intubation improved long-term success by 8%; local risk factors for scarring reduced success rates.
Conclusions:
- ELDCR requires adjunctive treatments to maintain nasal mucosal ostia for long-term success.
- Improvements in ostial patency are necessary for ELDCR to compete with external DCR beyond cosmetic and convenience factors.
