Is Laryngomalacia hereditary?

Here you can see if Laryngomalacia can be hereditary. Do you have any genetic components? Does any member of your family have Laryngomalacia or may be more predisposed to developing the condition?

Is Laryngomalacia hereditary?

Laryngomalacia is a condition characterized by the softening of the tissues of the larynx, leading to breathing difficulties in infants. While the exact cause is unknown, it is generally not considered to be hereditary. Laryngomalacia is believed to result from an underdeveloped larynx during fetal development. It is important to consult with a healthcare professional for a proper diagnosis and guidance on managing the condition.



Is Laryngomalacia hereditary?


Laryngomalacia is a medical condition that affects the larynx, or voice box, in infants. It is characterized by the softening of the tissues in the larynx, which can cause the airway to collapse during breathing. This can result in noisy breathing, stridor (a high-pitched sound during inhalation), and other respiratory difficulties.


When it comes to the hereditary nature of laryngomalacia, it is important to understand that the condition is primarily considered to be acquired rather than inherited. This means that it is not typically passed down from parents to their children through genetic factors.


Laryngomalacia is believed to be caused by an underdeveloped larynx in infants. The exact reasons behind this underdevelopment are not fully understood, but several factors may contribute to its occurrence. These factors include:



  • Premature birth: Babies born prematurely are more likely to develop laryngomalacia due to their larynx being less developed.

  • Anatomy: Some infants may have anatomical abnormalities that affect the structure and function of the larynx, increasing the risk of laryngomalacia.

  • Neuromuscular conditions: Certain neuromuscular disorders can impact the muscles and nerves involved in laryngeal function, potentially leading to laryngomalacia.

  • Gastroesophageal reflux (GERD): In some cases, the reflux of stomach acid into the throat can irritate the larynx and contribute to the development of laryngomalacia.


While laryngomalacia is not typically considered a hereditary condition, it is important to note that there may be a genetic predisposition for certain anatomical or developmental factors that increase the likelihood of laryngomalacia. This means that if a parent or close family member has had laryngomalacia, there may be a slightly higher chance of their child developing the condition as well.


It is crucial to consult with a healthcare professional, such as a pediatrician or otolaryngologist, for a proper diagnosis and guidance if laryngomalacia is suspected in an infant. They can evaluate the specific circumstances and provide appropriate treatment options, which may include observation, medical management, or, in rare cases, surgical intervention.
