Hello and welcome to the Zero to Finals podcast. My name is Tom and in this episode I'm going to be

talking to you about Loringo Malaysia. If you want to follow along with written notes on this topic,

you can follow along at zero definals.com slash loringo Malaysia or in the respiratory section

of the Zero to Finals Pediatrics book. So let's get straight

into it. Laringo Malaysia. Loringo Malaysia is a condition that affects infants where the part of the

larynx above the vocal cords, which is called the suproglotic larynx, is structured in a way that

allows it to cause partial airway obstruction.

And this leads to a chronic stridor during inspiration when the larynx flops across the

airway as the child breathes in. Strider is a harsh whistling sound that's caused by air

being forced through an obstruction of the upper

airway. Let's talk about the structural changes that occur in laryngo-Malacia. There are two

ary-epaglotic folds at the entrance of the larynx, and they run between the epiglottis and

the aritanoid cartilages. They are either side of the airway and their

role is to constrict the opening of the airway to prevent food or fluids from entering the larynx

and the trachea. In laryngo malaysia, the Ariepaglotic folds are shortened, which pulls on

the epiglottis and changes its shape into a characteristic omega shape.

In patients who have laryngomalacia, the tissue that surrounds the superglotic larynx is softer and has

less tone, and this means it can flop across the airway. This happens particularly during

inspiration as the airway moves through the

larynx to the lungs and pulls the floppy tissue across the airway to partially occlude it.

This partial obstruction of the airway generates the whistling sound, which is stridor.

So how did it present? Well, laryngomalacia occurs in infants and it peaks around six months of
