Airway malacia, also known as tracheobronchomalacia, is a condition characterized by the weakening or collapse of the walls of the airway, which can result in various respiratory symptoms. It can affect both children and adults and can range from mild to severe. In this blog, we will explore the common symptoms of airway malacia, which include breathing difficulties, coughing, and recurrent respiratory infections.
- Difficulty Breathing: One of the primary symptoms of airway malacia is difficulty breathing, particularly during exertion or when lying flat. The weakened or collapsible airway may not stay open properly, leading to increased resistance to airflow and making it harder for air to move in and out of the lungs. This can result in shortness of breath, wheezing, and a sensation of not getting enough air. In infants, this may be observed as retractions, which are inward pulling of the chest wall during breathing, or stridor, which is a high-pitched sound that occurs during inspiration.
- Coughing: Chronic or persistent coughing can be another symptom of airway malacia. The cough may be dry or produce mucus, and it may worsen when lying flat or during physical activity. The coughing may be a reflex response to the airway collapse or irritation caused by the weakened airway walls.
- Recurrent Respiratory Infections: Airway malacia can increase the risk of recurrent respiratory infections such as bronchitis, pneumonia, and upper respiratory tract infections. The weakened airway may be more prone to trapping mucus and bacteria, leading to infections. Frequent respiratory infections can further exacerbate the breathing difficulties and coughing associated with airway malacia.
- Noisy Breathing: Airway malacia can cause noisy breathing, such as wheezing, rattling, or stridor. These sounds may be heard during breathing and can be more prominent during certain positions or activities, such as lying flat or during physical exertion.
- Difficulty Swallowing: In some cases, airway malacia can also affect swallowing. The weakened or collapsed airway may interfere with the normal swallowing process, leading to difficulties in swallowing food or liquids. This can result in choking or gagging episodes, or regurgitation of food or liquids into the airway.
- Exercise Intolerance: Due to the increased resistance to airflow and breathing difficulties associated with airway malacia, individuals may experience exercise intolerance. Physical activities that require increased breathing effort, such as exercise or playing sports, may be challenging and may cause symptoms to worsen.
It’s important to note that the severity and presentation of symptoms can vary depending on the location and extent of the airway malacia. Some individuals may have mild symptoms that do not significantly impact their daily life, while others may have more severe symptoms that affect their quality of life and require medical intervention.
If you suspect that you or your child may have airway malacia, it’s important to consult a healthcare professional for a proper diagnosis. Diagnosis typically involves a thorough medical history, physical examination, and may include imaging studies such as a flexible bronchoscopy or CT scan to evaluate the airway. Treatment options for airway malacia may include supportive measures such as positioning techniques, respiratory therapies, or medication to manage symptoms. In severe cases, surgical interventions such as airway stenting or reconstructive surgeries may be considered.
In conclusion, airway malacia is a condition characterized by weakened or collapsed airway walls, which can lead to various respiratory symptoms such as difficulty breathing, coughing, recurrent respiratory infections, noisy breathing, difficulty swallowing, and exercise intolerance. If you suspect you or your child may have airway malacia, it’s important to seek medical evaluation and discuss appropriate treatment options
