What is the most common cause of a congenital stridor?
Laryngomalacia
What is the most common cause of an exacerbation of laryngomalacia?
An intercurrent respiratory tract infection
Outline how the diagnosis of laryngomalacia may be confirmed?
Flexible laryngoscopy; demonstrates prolapse over the airway of an omega(Ω)-shaped epiglottis
What is meant by stridor?
Stridor is an inspiratory sound secondary to narrowing of the upper airway
Outline the main difference between stridor and a wheeze?
Stridor is caused by upper respiratory tract narrowing whereas a wheeze is caused by lower respiratory tract narrowing
What procedures need to be avoided in children with stridor?
- Anything that may cause the child upset (blood tests, cannulas etc.) as it may cause deterioration<br></br>- The upper airway must not be examined either to prevent total obstruction

It is carried out between 5-8 days so as to give the baby enough time to latch and begin feeding normally, this will alow detection of metabolic disorders
