Insights
Endoscopic endonasal dacryocystorhinostomy effectively treats blocked tear ducts in children when other methods fail. The procedure provided significant symptom relief and restored tear duct patency in most young patients.
Area of Science:
- Ophthalmology
- Pediatric Surgery
- Rhinology
Background:
- Nasolacrimal duct blockage is a common condition in children.
- Conventional treatments like medical therapy and probing may not always be successful.
- Surgical intervention is sometimes necessary for refractory cases.
Purpose of the Study:
- To evaluate the efficacy and safety of endoscopic endonasal dacryocystorhinostomy (EEDCR) in pediatric patients.
- To assess symptom resolution and nasolacrimal duct patency following EEDCR.
- To determine the role of EEDCR in children with intractable nasolacrimal duct blockage.
Main Methods:
- A prospective interventional study was conducted.
- Twenty pediatric patients (2-12 years) with refractory nasolacrimal duct blockage were included.
- Nasolacrimal duct patency was confirmed via syringing; success was measured by symptom resolution and duct patency at 6 months.
Main Results:
- Complete symptomatic relief was achieved in 85% of patients at 6 months.
- Partial relief was reported in 5%, with no relief in 10%.
- Nasolacrimal duct patency was observed in 85% of patients, with partial patency in 10% and blockage in 5%.
Conclusions:
- Endoscopic endonasal dacryocystorhinostomy is a safe and effective surgical option for pediatric nasolacrimal duct blockage.
- EEDCR offers a high success rate in children unresponsive to medical therapy and probing.
- This minimally invasive approach provides a viable solution for improving quality of life in affected children.
Abstract:
We conducted a prospective interventional study to evaluate the role of endoscopic endonasal dacryocystorhinostomy in children. Our study population was made up of 20 patients-18 boys and 2 girls, aged 2 to 12 years (mean: 5.3)-who presented with signs and symptoms suggestive of nasolacrimal duct blockage that was refractory to conventional medical treatment. In all cases, blockage was confirmed by nasolacrimal duct syringing that demonstrated regurgitation from the opposite punctum. The primary outcome measures for success were resolution of symptoms and duct patency on lacrimal irrigation. At 6 months, 17 patients (85%) experienced complete symptomatic relief, 1 (5%) had partial relief, and 2 (10%) reported no relief. Moreover, the nasolacrimal duct was patent in 17 patients, partially patent in 2, and blocked in 1. We conclude that endoscopic endonasal dacryocystorhinostomy is a safe and effective procedure in children with nasolacrimal duct blockage when medical therapy and probing have been unsuccessful.
