Insights
Endoscopic endonasal dacryocystorhinostomy is a safe and effective treatment for pediatric nasolacrimal duct obstruction resistant to probing. This study shows a high success rate, making it a viable surgical option for children.
Area of Science:
- Ophthalmology
- Pediatric Surgery
Background:
- Nasolacrimal duct obstruction (NLDO) is common in children.
- Previous treatments like probing often fail in persistent cases.
Purpose of the Study:
- To evaluate the efficacy and safety of endonasal endoscopic dacryocystorhinostomy (DCR) in pediatric patients with NLDO.
- To determine if this technique is a valid alternative for children with NLDO refractory to probing.
Main Methods:
- A clinical cohort study involving 27 children aged 2-12 years with NLDO.
- All patients had previously undergone unsuccessful probing.
- The procedure involved uncinectomy and a small lacrimal sac opening, with a 3-month follow-up.
Main Results:
- A success rate of 77.8% (21 out of 27 surgeries) was achieved.
- The sole complication reported was silicone prolapse in one patient.
Conclusions:
- Endoscopic endonasal DCR is an acceptable and safe surgical method for pediatric NLDO.
- The technique demonstrates effectiveness in cases resistant to less invasive treatments like probing.
Aim:
To verify whether our results with endonasal endoscopic dacryocystorhinostomy in children with nasolacrimal duct obstruction allow us to consider this technique a valid treatment alternative for children.
Study Design:
clinical with transversal cohort.
Material And Method:
Twenty-seven endoscopic endonasal dacryocystorhinostomies were performed in children 2 to 12 years of age for nasolacrimal duct obstruction. Previous probings in all patients were unsuccessful. The technique employed uncinectomy and a small lacrimal sac opening. Follow-up time was 3 months.
Results:
Twenty-one surgeries (77,8%) were successful. The only complication was silicone prolapse in one case.
Conclusion:
Our results confirm endoscopic endonasal dacryocystorhinostomy as an acceptable and safe method for treating children with nasolacrimal duct obstructions that are resistant to probings.

Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
