When to see a doctor
If you experience severe or worsening symptoms, seek immediate medical attention. Always consult with a healthcare professional for proper diagnosis and treatment.
Causes & Risk Factors
Several factors can contribute to Laryngomalacia.
Laryngomalacia develops when the cartilage supporting the larynx fails to mature properly during fetal development.
Laryngomalacia develops when the cartilage supporting the larynx fails to mature properly during fetal development. Think of it like a garden hose that should be firm enough to stay open when water flows through it. In laryngomalacia, the "hose" - the cartilage around the voice box - remains too soft and flexible, causing it to collapse when air tries to pass through.
The exact reason why some babies develop this condition while others don't remains unclear to medical researchers.
The exact reason why some babies develop this condition while others don't remains unclear to medical researchers. Most cases appear to be isolated developmental variations rather than inherited genetic disorders. The immature cartilage particularly affects the area above the vocal cords called the supraglottis, which includes structures like the epiglottis and aryepiglottic folds.
In some instances, laryngomalacia occurs alongside other congenital conditions affecting the airway or digestive system.
In some instances, laryngomalacia occurs alongside other congenital conditions affecting the airway or digestive system. Gastroesophageal reflux disease (GERD) can worsen laryngomalacia symptoms by causing swelling and inflammation in the already compromised airway. This creates a cycle where breathing difficulties make reflux worse, and reflux makes breathing problems more severe.
Risk Factors
- Male gender (boys affected twice as often as girls)
- Premature birth
- Low birth weight
- Gastroesophageal reflux disease (GERD)
- Other congenital airway abnormalities
- Neurological conditions affecting muscle tone
- Family history of laryngeal disorders
- Certain genetic syndromes
- Maternal smoking during pregnancy
Diagnosis
How healthcare professionals diagnose Laryngomalacia:
- 1
Diagnosing laryngomalacia typically begins when parents notice unusual breathing sounds in their newborn.
Diagnosing laryngomalacia typically begins when parents notice unusual breathing sounds in their newborn. Pediatricians can often suspect the condition based on the characteristic stridor and breathing patterns, but confirming the diagnosis requires specialized examination. The distinctive inspiratory stridor - the fluttery sound that occurs when breathing in - provides the first clue.

The gold standard for diagnosis is flexible laryngoscopy, a procedure where a thin, flexible scope with a tiny camera is gently inserted through the nose to visualize the larynx.
The gold standard for diagnosis is flexible laryngoscopy, a procedure where a thin, flexible scope with a tiny camera is gently inserted through the nose to visualize the larynx. This allows doctors to see the floppy tissue collapsing into the airway during breathing. The procedure can be performed in the office and provides immediate visual confirmation of the diagnosis. During the exam, doctors look for the characteristic omega-shaped epiglottis and inward collapse of the aryepiglottic folds.

Additional tests may include sleep studies if breathing problems interfere with rest, swallowing studies if feeding difficulties are present, and pH monitoring to check for acid reflux.
Additional tests may include sleep studies if breathing problems interfere with rest, swallowing studies if feeding difficulties are present, and pH monitoring to check for acid reflux. Doctors also assess the severity by observing how the condition affects feeding, growth, and daily activities. Mild cases might only produce noise, while severe cases can cause significant breathing distress and feeding problems that require immediate attention.
Complications
- Most children with laryngomalacia experience mild symptoms that resolve naturally as they grow, but severe cases can lead to several complications if left untreated.
- Feeding difficulties represent the most common complication, as the increased breathing effort required during eating can cause babies to tire quickly, choke, or refuse feeds altogether.
- This can result in poor weight gain, dehydration, and failure to thrive that may require nutritional support or feeding modifications.
- Respiratory complications can develop when the airway obstruction becomes severe enough to interfere with normal oxygen levels.
- Chronic breathing difficulties may lead to increased work of breathing, fatigue, and in rare cases, episodes of low oxygen that cause blue discoloration around the lips or face.
- Sleep disturbances are common, as the breathing difficulties often worsen when children lie flat, leading to restless nights for both babies and parents.
- With proper treatment, these complications typically resolve completely, and children go on to develop normal breathing, feeding, and growth patterns.
Prevention
- Since laryngomalacia stems from developmental variations that occur during fetal growth, there are no proven methods to prevent the condition entirely.
- The immature cartilage development happens early in pregnancy, before many women even know they're expecting.
- However, maintaining good prenatal health may support optimal fetal development overall.
- Pregnant women can focus on general measures that promote healthy fetal development: taking prenatal vitamins with folic acid, avoiding smoking and alcohol, maintaining a healthy diet, and attending regular prenatal appointments.
- While these steps don't specifically prevent laryngomalacia, they support the best possible conditions for normal organ development.
- For families with a child diagnosed with laryngomalacia, preventing complications becomes the primary focus.
- Managing associated gastroesophageal reflux through proper feeding techniques, positioning, and medication when prescribed can prevent worsening of symptoms.
- Protecting children from respiratory infections through good hygiene and avoiding exposure to sick individuals helps prevent additional airway inflammation that could worsen breathing difficulties.
Treatment for laryngomalacia depends entirely on the severity of symptoms and how much the condition interferes with a baby's daily life.
Treatment for laryngomalacia depends entirely on the severity of symptoms and how much the condition interferes with a baby's daily life. For mild cases that only cause noisy breathing without feeding problems or breathing distress, doctors typically recommend watchful waiting. Most children naturally outgrow the condition as their laryngeal cartilage strengthens and matures over the first two years of life.
When gastroesophageal reflux accompanies laryngomalacia, treating the reflux often significantly improves breathing symptoms.
When gastroesophageal reflux accompanies laryngomalacia, treating the reflux often significantly improves breathing symptoms. Doctors may prescribe acid-blocking medications, recommend feeding modifications like smaller more frequent meals, and suggest keeping babies upright after feeding. These conservative measures can reduce airway inflammation and make breathing easier.
Severe laryngomalacia that causes feeding difficulties, poor weight gain, or significant breathing problems requires surgical intervention.
Severe laryngomalacia that causes feeding difficulties, poor weight gain, or significant breathing problems requires surgical intervention. The most common procedure is supraglottoplasty, where surgeons trim away the excess floppy tissue that collapses into the airway. This outpatient surgery has a high success rate, with most children experiencing immediate improvement in breathing and feeding. The procedure is performed through the mouth using specialized instruments, leaving no external scars.
Post-surgical care focuses on monitoring for complications and ensuring proper healing.
Post-surgical care focuses on monitoring for complications and ensuring proper healing. Most babies can go home the same day or after an overnight observation. Parents learn to recognize signs of airway swelling or breathing difficulties that might require immediate medical attention. Long-term outcomes are excellent, with the vast majority of children developing normal voice and breathing patterns.
Living With Laryngomalacia
Parents of babies with laryngomalacia often find the noisy breathing alarming at first, but learning about the condition helps reduce anxiety and build confidence in managing daily care. Most families discover that certain positions make breathing easier for their child - keeping babies upright during and after feeding, using a slightly elevated sleeping position, and staying calm during episodes of increased stridor can all help. Many parents become expert at distinguishing between their child's normal breathing sounds and signs that might require medical attention.
