Summary
Powered endoscopic dacryocystorhinostomy (DCR) without mucosal flap preservation effectively manages acquired nasolacrimal duct obstruction, achieving high rates of epiphora resolution and anatomical patency.
Area of Science:
- Ophthalmology
- Otolaryngology
Background:
- Acquired nasolacrimal duct obstruction causes epiphora.
- Endoscopic dacryocystorhinostomy (DCR) is a surgical treatment.
Purpose of the Study:
- To evaluate outcomes of powered endoscopic DCR without preserving mucosal flaps.
- To assess the efficacy in managing acquired nasolacrimal duct obstruction.
Main Methods:
- Retrospective review of 27 procedures in 20 patients (May 2003-Oct 2006).
- Inclusion criteria: epiphora secondary to acquired nasolacrimal duct obstruction.
- Outcome measures: subjective epiphora improvement and lacrimal irrigation for patency.
Main Results:
- 100% of procedures showed mild intermittent or complete epiphora resolution.
- 93% of procedures achieved complete epiphora resolution.
- 100% anatomical patency confirmed by lacrimal irrigation in available patients at 16-month follow-up.
Conclusions:
- Powered endoscopic DCR without mucosal flap preservation yields comparable outcomes to published methods.
- This technique is a successful approach for acquired nasolacrimal duct obstruction management.
