Summary
Endoscopic dacryocystorhinostomy (DCR) effectively treats persistent nasolacrimal duct obstruction (NLDO) in children when other methods fail. This minimally invasive approach offers a safe and scarless alternative for pediatric patients.
Area of Science:
- Ophthalmology
- Pediatric Surgery
- Otolaryngology
Background:
- Persistent nasolacrimal duct obstruction (NLDO) often necessitates surgical intervention.
- Traditional external dacryocystorhinostomy (DCR) is effective but results in scarring and is often avoided in children.
- Endoscopic DCR offers a less invasive alternative.
Purpose of the Study:
- To evaluate the efficacy and safety of endoscopic DCR in pediatric patients with persistent NLDO.
- To assess the success rate of endoscopic DCR after failed initial treatments.
Main Methods:
- Retrospective review of endoscopic lacrimal procedures over 3 years.
- Seventeen children (22 ducts) with persistent NLDO underwent endoscopic DCR after failed probing/intubation.
- Success defined by resolution of symptoms; follow-up ranged from 6 to 36 months.
Main Results:
- 88% of patients experienced complete resolution of tearing and discharge.
- Two patients required revision endoscopic DCR for recurrent symptoms.
- No complications were reported during the study period.
Conclusions:
- Endoscopic DCR is a safe and effective treatment for persistent NLDO in pediatric patients unresponsive to simpler procedures.
- The combined ophthalmology-otolaryngology endoscopic approach provides a successful alternative to external DCR.
- This technique is particularly beneficial for distal obstructions in children, avoiding external scarring.

01:21Tracheostomy Decannulation
Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
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...

01:29Suctioning the Nasopharyngeal Airway
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.
