Laryngomalacia
Laryngomalacia is a congenital condition that affects the opening of the windpipe, causing obstructions to occur. This condition develops because of the floppy tissue that surrounds the voice box, as it collapses and restricts proper airflow. This can lead to a distinctive high-pitch wheezing sound when breathing, feeding difficulties, or shortness of breath. Laryngomalacia tends to be more common among newborns and infants, but it may also affect older children and adults. Most children often outgrow the process as the tissue around the voice box strengthens as they grow. In severe cases, treatments such as surgery or breathing support may be necessary to help alleviate symptoms. It is essential for parents to contact their child’s medical provider if they experience any concerns regarding their breathing or feeding.
Symptoms of Laryngomalacia
What are the common symptoms of laryngomalacia?
The common symptoms of laryngomalacia include stridor (a high-pitched wheezing sound when breathing in), difficulty breathing, feeding difficulties, nasal flaring, retractions (pulling in of the chest during breathing), and cyanosis (bluish tint to the skin and mucous membranes).
What factors cause laryngomalacia in infants?
The exact cause of laryngomalacia is unknown, but factors such as genetics, abnormal neuromuscular control of the larynx, premature birth, and exposure to maternal smoking during pregnancy may contribute to its development.
How does laryngomalacia affect a child`s breathing?
Laryngomalacia can affect a child`s breathing by causing obstruction in the airway, leading to difficulty in breathing, and impact on feeding. It results mainly from the collapse of the larynx.
Is gastroesophageal reflux a possible cause of laryngomalacia?
Gastroesophageal reflux (GER) can be a possible cause of laryngomalacia. However, studies have shown that the incidence of GER in infants with laryngomalacia is no higher than in infants without laryngomalacia.
What are the potential consequences of untreated laryngomalacia?
Untreated laryngomalacia can result in worsening symptoms, failure to thrive, and recurrent respiratory tract infections. Severe cases may require emergency intervention such as intubation or a tracheostomy. Early diagnosis and treatment can lead to better outcomes for affected infants.
Diagnosis of Laryngomalacia
What diagnostic tools are commonly used to identify laryngomalacia?
Diagnostic tools commonly used to identify laryngomalacia include laryngoscopy, bronchoscopy, and videofluoroscopy. Laryngoscopy is considered the gold standard for diagnosis, as it provides direct visualization of the larynx and can identify the characteristic signs of laryngomalacia, such as inward collapse of the arytenoid cartilages during inspiration. However, other tests may be necessary to evaluate the severity and extent of the condition, particularly in cases where the findings on laryngoscopy are inconclusive.
Is laryngoscopy considered a reliable diagnostic test for laryngomalacia?
Chest X-rays are not generally helpful in diagnosing laryngomalacia, as the condition primarily affects the upper respiratory tract and does not typically cause changes in lung function or structure. However, X-rays may be ordered to rule out other underlying lung or cardiac conditions that can present with similar symptoms.
Can a chest X-ray help diagnose laryngomalacia?
The major signs and symptoms used to diagnose laryngomalacia include inspiratory stridor, which is a high-pitched, wheezing sound that occurs during breathing, particularly during sleep or periods of increased activity; retractions, in which the chest wall may visibly pull inward during inspiration due to the effort required to move air through the narrowed airway; and feeding difficulties, which may occur due to the increased effort required to suck and swallow with a compromised airway.
What are the major signs and symptoms used to diagnose laryngomalacia?
MRI scans are not typically used to diagnose laryngomalacia, as they do not offer significant advantages over other diagnostic modalities and can be more costly and time-consuming. However, they may be ordered in cases where other diagnostic tests are inconclusive or additional evaluation of the airway anatomy is necessary.

Treatments of Laryngomalacia
What are the primary treatment options for laryngomalacia?
The primary treatment options for laryngomalacia depend on the severity of the condition. Mild cases may improve on their own without any intervention, while more severe cases may require medical or surgical treatment. Conservative treatment options may include feeding changes or thickening of liquids, as well as positional management. In some cases, medication may be prescribed to reduce acid reflux, if that is contributing to the symptoms. In severe cases, surgery may be necessary to alleviate symptoms and increase airway function.
How can positioning be used to manage laryngomalacia symptoms?
Positioning can be used as a non-invasive way to manage laryngomalacia symptoms. Laryngomalacia affects the way the muscles around the glottis and larynx work, and this can cause breathing difficulties or noisy breathing. Reclining positions can help relieve the pressure on the chest and throat, allowing for better airflow. Additionally, sleeping with the head and chest elevated may reduce the symptoms of acid reflux, which can contribute to laryngomalacia. Positioning is often used in combination with other treatment options, especially for mild cases.
Are there any medications that can be used to treat laryngomalacia?
Medications can be used to manage laryngomalacia symptoms, but they will not cure the underlying condition. Some infants with laryngomalacia have acid reflux, and medications such as proton pump inhibitors or H2 receptor blockers can help reduce the symptoms of acid reflux. Other medications, such as bronchodilators or corticosteroids, may be used to reduce inflammation in the airway or improve breathing. It is important to consult a medical professional before giving any medication to an infant with laryngomalacia.
Can surgery be used as a treatment for severe cases of laryngomalacia?
Surgery may be used as a treatment for severe cases of laryngomalacia. The most common surgery for laryngomalacia is supraglottoplasty, which involves removing a portion of the floppy tissue around the glottis and larynx. This surgery can alleviate symptoms and improve airflow, but it is a significant procedure and requires general anesthesia. Other surgical options may include tracheostomy or other procedures to manage airway obstruction.
What post-operative care is necessary after laryngomalacia surgery?
After laryngomalacia surgery, careful post-operative care is necessary to prevent complications and ensure a successful recovery. This may include monitoring vital signs, assessing breathing and swallowing, and managing pain. Some infants may require supplemental oxygen or respiratory support after surgery. It is important to follow the instructions of the medical team and attend follow-up appointments to ensure that the infant is recovering properly. In some cases, speech therapy or feeding therapy may be recommended to help the infant re-learn how to use the muscles around the throat and larynx. Source:
Prognosis of Laryngomalacia
What is the typical long-term outcome of Laryngomalacia?
The typical long-term outcome of Laryngomalacia varies depending on the severity of the condition and its underlying cause. In most cases, children with mild to moderate Laryngomalacia will outgrow the condition by the age of 18-24 months. However, some children may experience persistent symptoms into early childhood, such as snoring, sleep disruption, and feeding difficulties. In more severe cases, Laryngomalacia can lead to complications such as chronic respiratory failure, apnea, and aspiration pneumonia, which can cause long-term health problems.
Does Laryngomalacia have a favorable prognosis?
Laryngomalacia generally has a favorable prognosis when properly diagnosed and managed. Early recognition and intervention can lead to a positive outcome, with most children experiencing a complete resolution of symptoms. However, the severity of the condition and the presence of underlying medical conditions can affect the prognosis, making it important to monitor and manage symptoms over the long-term.
What factors can affect the prognosis of Laryngomalacia?
Factors that can affect the prognosis of Laryngomalacia include the severity of the condition, the age at which symptoms appear, the presence of underlying medical conditions, and the effectiveness of treatment. Infants with severe forms of Laryngomalacia, or those with associated medical conditions such as Down Syndrome, are at increased risk of complications and may require more intensive treatment and monitoring.
Is prompt treatment crucial for a positive Laryngomalacia prognosis?
Prompt treatment is crucial for a positive Laryngomalacia prognosis, as early intervention can prevent complications and improve outcomes. Treatment may include conservative measures such as positioning and feeding modifications, or more aggressive interventions such as surgical procedures or medication therapy. Regular follow-up with a medical provider is also important to monitor symptoms and adjust treatment as needed.
Can Laryngomalacia resolve on its own without treatment, affecting its prognosis?
Laryngomalacia may resolve on its own without treatment in some cases, particularly in mild cases. However, for more severe forms of the condition or those with underlying medical conditions, treatment and monitoring are crucial for a positive prognosis. It is important to discuss any concerns or symptoms with a medical provider, as untreated Laryngomalacia can lead to complications and long-term health problems.
Prevention of Laryngomalacia
How can laryngomalacia be prevented?
Prevention of laryngomalacia is challenging due to its unknown cause. However, it is believed that genetics and environmental factors can play a role. Therefore, there are currently no specific preventative measures for laryngomalacia. 2. Feeding practices are not known to directly prevent laryngomalacia. However, proper feeding techniques, such as holding the baby properly during feedings, can help reduce symptoms and prevent complications. 3. Some studies have suggested that sleeping on the back may reduce the risk of developing laryngomalacia. However, it is important to follow safe sleep guidelines, including putting the baby on their back to sleep, to prevent Sudden Infant Death Syndrome (SIDS). 4. Environmental factors, such as exposure to second-hand smoke and pollution, can play a role in the development of laryngomalacia. Therefore, avoiding these environmental factors may help reduce the risk, but further research is needed. 5. There are currently no vaccines available for the prevention of laryngomalacia. However, maintaining proper hygiene and ensuring that the child receives all recommended vaccines can reduce the risk of other illnesses and infections that may exacerbate laryngomalacia symptoms.
