Insights
A rare cause of airway obstruction in children, impacted foreign bodies in the subglottis are often misdiagnosed as croup. Early consideration is crucial for timely diagnosis and treatment of pediatric stridor.
Area of Science:
- Pediatric Otolaryngology
- Pediatric Emergency Medicine
- Respiratory Tract Foreign Bodies
Background:
- Subglottic foreign bodies are an uncommon cause of upper airway obstruction in children.
- Diagnosis is frequently delayed due to lack of a clear history.
- This condition can mimic common pediatric respiratory illnesses like laryngotracheobronchitis (croup).
Purpose of the Study:
- To highlight the importance of considering subglottic foreign bodies in the differential diagnosis of pediatric stridor.
- To emphasize the challenges in diagnosing this rare condition.
- To improve recognition and reduce diagnostic delays.
Main Methods:
- Case review and literature synthesis.
- Analysis of clinical presentation and diagnostic challenges.
- Review of typical and atypical presentations of subglottic foreign bodies.
Main Results:
- Delayed diagnosis is common, often leading to prolonged symptoms.
- Misdiagnosis as croup or laryngotracheobronchitis is frequent.
- Subglottic foreign bodies present a diagnostic challenge despite rarity.
Conclusions:
- Subglottic foreign bodies should be a key consideration in children presenting with stridor.
- A high index of suspicion is necessary, especially when history is unclear.
- Prompt investigation can prevent complications associated with delayed diagnosis and treatment.
Abstract:
An impacted foreign body in the subglottis is a rare cause of upper airway obstruction in children. More often than not the diagnosis is delayed; especially where proper history is not forthcoming. This peculiar condition can masquade as laryngotracheobronchitis or a croup. Though it is rare, a foreign body in the subglottis should be kept in mind in the investigation of a child with stridor.

Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
