The Gastric Reflux Test (Multichannel Intraluminal Impedance Test) is performed to detect and record the number of times stomach contents come back into the esophagus and the relation of these episodes to symptoms (for example, when a child cries, arches, coughs, gags, vomits, has chest pain). Acid reflux, if it reaches the upper portion of the swallowing tube (esophagus) and voice box region, can cause additional swelling of the floppy tissue seen in LM. All babies reflux, but children with laryngomalacia may have more than other babies. There is a strong link between GERD and laryngomalacia. The X-rays can screen for other possible causes of noisy breathing in the upper airway, windpipe, chest and lungs. Your doctor may recommend more studies if these tests are abnormal. Some children may have an additional problem that may contribute to the noisy breathing. While looking at the voice box, your doctor may ask you to feed your baby from a bottle to see how well your baby does with feeding, especially if there is a history of choking on food or spitting up. If your child is seen in the Laryngomalacia Clinic at Cincinnati Children's Hospital Medical Center, the lighted tube is connected to a television camera so that the parent or caregiver can see what the voice box looks like. At the same time, they will look for any other throat / voice box problems that may contribute to the noisy breathing. The doctor looks at the position of the tissue above the voice box to determine if it is floppy. This test involves placement of a lighted tube through the nose or mouth to look at the voice box.

This test is required to confirm a diagnosis. However, the condition is confirmed by a clinical examination and flexible laryngoscopy. Your child’s doctor may suspect that your child has LM by simply gathering his / her medical history.

The part of the nervous system that gives tone to the airway is most likely underdeveloped.

The cause and reason why the tissue is floppy are unknown.

It is the most common birth defect of the voice box (larynx).

It is the most frequent cause of noisy breathing (stridor) in infants and children.

Laryngomalacia (LM) is best described as floppy tissue above the vocal cords thatįalls into the airway when a child breathes in. What Is Laryngomalacia (lə-ring′gō- mə-lā′shə)?
