Introduction
Laryngomalacia is a common condition in newborns and infants, characterized by noisy breathing (stridor) due to the softening of tissues in the larynx (voice box). It is the most frequent cause of stridor in infants, affecting approximately 60-70% of babies with congenital airway issues. Most cases are mild and resolve without intervention by 12-18 months of age.
Symptoms
- Noisy breathing (stridor): A high-pitched sound heard during inhalation, often worsening with crying, feeding, or lying on the back.
- Feeding difficulties: Poor latch, choking, or gasping during feeds.
- Mild retractions: Visible pulling in of the chest or neck muscles while breathing.
- Rare complications: Cyanosis (bluish skin) or severe respiratory distress (seek immediate care if these occur).
Causes
- Congenital immaturity: Underdeveloped cartilage and tissues in the larynx collapse inward during breathing.
- Neuromuscular factors: Weak muscle tone around the airway may contribute.
- Association with reflux: Gastroesophageal reflux (GERD) can worsen symptoms.
Diagnosis
- Physical exam: A pediatrician listens for stridor and observes breathing patterns.
- Flexible laryngoscopy: An ENT specialist uses a tiny camera to view the larynx and confirm the diagnosis.
- Rule out other conditions: Differentiate from tracheomalacia, croup, or vocal cord paralysis.
Treatment
- Mild cases: Reassurance and monitoring. Most infants outgrow it by 18 months.
- Positioning: Keep the baby upright during feeds and sleep (follow safe sleep guidelines).
- Acid reflux management: Medications (e.g., antacids) if GERD exacerbates symptoms.
- Severe cases (1-5%): Surgery (supraglottoplasty) to trim excess tissue and improve airflow.
When to Seek Help
Contact a doctor immediately if your baby:
- Struggles to breathe (flaring nostrils, rapid breathing).
- Turns blue (cyanosis) or becomes lethargic.
- Fails to gain weight or shows signs of dehydration.
Parent Tips
- Feed upright: Use angled bottles and burp frequently.
- Monitor growth: Track weight gain with your pediatrician.
- Avoid smoke exposure: Smoke can worsen respiratory symptoms.
Common Questions
- Will it affect speech?: No, unless severe complications arise.
- Can adults develop it?: Rarely; usually linked to neuromuscular disorders.
- Recurrence risk: Extremely low once resolved.
Outlook
Most infants thrive with minimal intervention. Surgery, if needed, has a 90% success rate. Regular follow-ups ensure proper growth and airway development.

Final Note
While laryngomalacia can be alarming, it is typically manageable. Trust your pediatrician’s guidance and stay vigilant for any concerning signs.
