Summary
Endonasal Dacryocystorhinostomy (EnDCR) is effective for chronic dacryocystitis. Silicon intubation in EnDCR shows a high success rate, potentially improving outcomes by maintaining rhinostomy patency.
Area of Science:
- Ophthalmology
- Otorhinolaryngology
Background:
- Chronic dacryocystitis often requires surgical intervention.
- Endonasal Dacryocystorhinostomy (EnDCR) is a minimally invasive surgical approach.
Purpose of the Study:
- To evaluate the efficacy of EnDCR in the Indian population.
- To assess the role and impact of silicon intubation in EnDCR outcomes.
Main Methods:
- Prospective case series involving 290 patients undergoing EnDCR.
- Comparison between 240 cases without silicon intubation and 50 cases with silicon intubation.
- Outcomes assessed subjectively and objectively with average follow-up periods of 18.6 and 5.2 months, respectively.
Main Results:
- EnDCR without silicon intubation achieved a success rate of 93.3%.
- EnDCR with silicon intubation demonstrated a success rate of 96%.
- Silicon intubation showed a slightly higher success rate.
Conclusions:
- EnDCR is a safe and effective procedure for chronic dacryocystitis.
- Silicon intubation appears to aid in maintaining the patency of the rhinostomy, potentially improving success rates.
- EnDCR with silicon intubation offers advantages in managing nasolacrimal duct obstruction.
