Laryngomalacia presenting as severe uncontrolled asthma

Area of Science:

• Pediatric Pulmonology
• Otolaryngology

Background:

• Congenital laryngomalacia is the primary cause of infant stridor, typically resolving by 18 months.
• Emerging evidence suggests potential long-term structural and functional impacts.
• Late-onset stridor, sometimes post-infection, raises diagnostic questions.

Purpose of the Study:

• To explore the potential long-term consequences of congenital laryngomalacia.
• To investigate the relationship between milder/undiagnosed laryngomalacia and later respiratory symptoms.
• To differentiate laryngomalacia from conditions like childhood asthma.

Main Methods:

• Review of recent studies on laryngomalacia outcomes.
• Analysis of case reports detailing unusual presentations and late-onset stridor.
• Comparison of clinical features between laryngomalacia and adult asthma.

Main Results:

• Laryngomalacia may result in persistent respiratory symptoms into later life.
• Undiagnosed or mild forms could manifest as late-onset stridor, sometimes triggered by infections.
• Absence of airway hyperresponsiveness in some adults questions prior asthma diagnoses.

Conclusions:

• Congenital laryngomalacia can have enduring effects beyond infancy.
• Distinguishing laryngomalacia from severe asthma is crucial for accurate diagnosis and management.
• Further research is needed to understand the long-term sequelae of all laryngomalacia presentations.
