Pediatric flexible bronchoscopy frequently reveals upper airway malacia disorders, which are the most common finding. Early diagnosis of these congenital and acquired abnormalities can prevent unnecessary long-term treatments for chronic respiratory issues in children.
Area of Science:
- Pediatric Pulmonology
- Airway Endoscopy
- Respiratory Distress
Background:
- Upper airway obstruction requires rapid anatomical evaluation to determine severity and respiratory distress.
- Airway endoscopy is crucial for both diagnosing and treating pediatric airway conditions.
Purpose of the Study:
- To document upper airway abnormalities detected during flexible bronchoscopy in pediatric patients.
- To analyze findings from two major Turkish pediatric pulmonology centers.
Main Methods:
- Retrospective analysis of 1076 pediatric cases with pulmonary/airway disease.
- Flexible bronchoscopy performed between 2007 and 2011.
Main Results:
- Upper airway malacia disorders were the most common finding (79.6%).
- Other frequent pathologies included laryngeal edema (12.9%), external tracheal compression (12.3%), and subglottic stenosis (4.0%).
- Symptom duration varied significantly by diagnosis, being shortest for vocal cord paralysis.
Conclusions:
- Congenital and acquired upper airway abnormalities, particularly malacia, should be considered in children with chronic respiratory problems.
- Prompt diagnosis allows for discontinuation of unnecessary long-term antibiotic or antiasthmatic therapies.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
