Living with Congenital laryngomalacia

A condition in infants where soft voice box tissue collapses inward during breathing in, causing noisy breathing.

Understanding Congenital laryngomalacia

Congenital laryngomalacia is a voice box (larynx) condition in which the airway collapses inward when air is drawn in.

It usually shows up at birth or soon after. The most common sign is noisy breathing (stridor), often worse when the baby is on their back or crying. In more severe cases there can be harder breathing with the chest pulling in, poor weight gain from feeding difficulty, pauses in breathing and blue color. Most cases occur with no family history.

Signs & symptoms

Symptoms vary from person to person. GARD's summary lists these:

  • Noisy breathing (stridor)
  • Chest pulling inward when breathing
  • Poor weight gain from feeding difficulty
  • Pauses in breathing (apnea)
  • Blue skin color (cyanosis)
  • Voice changes

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include ear, nose, and throat specialists and genetic specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Cure TBM may keep lists of experts for this condition.
