Congenital Laryngomalacia: Pathophysiology, Clinical Spectrum, and Holistic Management

Area of Science:

• Pediatric Otolaryngology
• Neonatal Medicine
• Respiratory Physiology

Background:

• Congenital laryngomalacia is the leading cause of stridor in infants.
• It results from complex structural, neuromuscular, and inflammatory factors causing dynamic supraglottic collapse.
• Severity ranges from mild stridor to severe obstruction, impacting growth and feeding.

Purpose of the Study:

• To review the pathophysiology, diagnosis, and management of congenital laryngomalacia.
• To highlight the spectrum of disease severity and influencing factors.
• To evaluate treatment outcomes for conservative and surgical interventions.

Main Methods:

• Review of current literature on congenital laryngomalacia.
• Analysis of diagnostic modalities including flexible laryngoscopy and swallowing studies.
• Evaluation of treatment strategies: conservative management, acid suppression, and supraglottoplasty.

Main Results:

• Infant stridor is most commonly caused by congenital laryngomalacia.
• Flexible laryngoscopy is the primary diagnostic tool, with further investigations as needed.
• Conservative management, especially feeding modifications, is effective for most infants.
• Supraglottoplasty demonstrates significant efficacy and durability for severe cases.

Conclusions:

• Congenital laryngomalacia requires a multifaceted approach to management.
• Early diagnosis and tailored interventions are crucial for optimal infant outcomes.
• Surgical intervention like supraglottoplasty significantly improves quality of life for affected infants and families.
