Endoscopic dacryocystorhinostomy is an effective treatment for persistent epiphora in adults and children, demonstrating high success rates and a low complication profile. This minimally invasive procedure offers excellent outcomes comparable to traditional methods.
Area of Science:
- Ophthalmology
- Otorhinolaryngology
Background:
- Nasolacrimal duct obstruction causes persistent epiphora, impacting quality of life.
- Endoscopic dacryocystorhinostomy (DCR) is a minimally invasive surgical option.
Purpose of the Study:
- To evaluate the efficacy and safety of endoscopic dacryocystorhinostomy.
- To report outcomes over a 14-year period in a large patient cohort.
Main Methods:
- Retrospective case series of 624 endoscopic DCR procedures in 442 patients (1999-2014).
- Data collected included demographics, complications, and follow-up outcomes.
- Patients were stratified by age (adults/children) and epiphora type (congenital/acquired/functional).
Main Results:
- High anatomical success rates: 90.1% in adults and 91.5% in children.
- Functional success was observed in 91% of adult functional epiphora cases.
- Overall complication rate was low at 3.2%.
Conclusions:
- Endoscopic dacryocystorhinostomy is a safe and effective treatment for persistent epiphora in both adults and children.
- The procedure achieves success rates comparable to the traditional external approach.
- Offers good outcomes for congenital, acquired, and functional nasolacrimal duct obstruction.
